+ Frequently Asked Questions about zlib
+
+
+If your question is not there, please check the zlib home page
+http://www.zlib.org which may have more recent information.
+The lastest zlib FAQ is at http://www.gzip.org/zlib/zlib_faq.html
+
+
+ 1. Is zlib Y2K-compliant?
+
+ Yes. zlib doesn't handle dates.
+
+ 2. Where can I get a Windows DLL version?
+
+ The zlib sources can be compiled without change to produce a DLL.
+ See the file win32/DLL_FAQ.txt in the zlib distribution.
+ Pointers to the precompiled DLL are found in the zlib web site at
+ http://www.zlib.org.
+
+ 3. Where can I get a Visual Basic interface to zlib?
+
+ See

+
+ 4. compress() returns Z_BUF_ERROR.
+
+ Make sure that before the call of compress, the length of the compressed
+ buffer is equal to the total size of the compressed buffer and not
+ zero. For Visual Basic, check that this parameter is passed by reference
+ ("as any"), not by value ("as long").
+
+ 5. deflate() or inflate() returns Z_BUF_ERROR.
+
+ Before making the call, make sure that avail_in and avail_out are not
+ zero. When setting the parameter flush equal to Z_FINISH, also make sure
+ that avail_out is big enough to allow processing all pending input.
+ Note that a Z_BUF_ERROR is not fatal--another call to deflate() or
+ inflate() can be made with more input or output space. A Z_BUF_ERROR
+ may in fact be unavoidable depending on how the functions are used, since
+ it is not possible to tell whether or not there is more output pending
+ when strm.avail_out returns with zero.
+
+ 6. Where's the zlib documentation (man pages, etc.)?
+
+ It's in zlib.h for the moment, and Francis S. Lin has converted it to a
+ web page zlib.html. Volunteers to transform this to Unix-style man pages,
+ please contact us (zlib@gzip.org). Examples of zlib usage are in the files
+ example.c and minigzip.c.
+
+ 7. Why don't you use GNU autoconf or libtool or ...?
+
+ Because we would like to keep zlib as a very small and simple
+ package. zlib is rather portable and doesn't need much configuration.
+
+ 8. I found a bug in zlib.
+
+ Most of the time, such problems are due to an incorrect usage of
+ zlib. Please try to reproduce the problem with a small program and send
+ the corresponding source to us at zlib@gzip.org . Do not send
+ multi-megabyte data files without prior agreement.
+
+ 9. Why do I get "undefined reference to gzputc"?
+
+ If "make test" produces something like
+
+ example.o(.text+0x154): undefined reference to `gzputc'
+
+ check that you don't have old files libz.* in /usr/lib, /usr/local/lib or
+ /usr/X11R6/lib. Remove any old versions, then do "make install".
+
+10. I need a Delphi interface to zlib.
+
+ See the contrib/delphi directory in the zlib distribution.
+
+11. Can zlib handle .zip archives?
+
+ Not by itself, no. See the directory contrib/minizip in the zlib
+ distribution.
+
+12. Can zlib handle .Z files?
+
+ No, sorry. You have to spawn an uncompress or gunzip subprocess, or adapt
+ the code of uncompress on your own.
+
+13. How can I make a Unix shared library?
+
+ make clean
+ ./configure -s
+ make
+
+14. How do I install a shared zlib library on Unix?
+
+ After the above, then:
+
+ make install
+
+ However, many flavors of Unix come with a shared zlib already installed.
+ Before going to the trouble of compiling a shared version of zlib and
+ trying to install it, you may want to check if it's already there! If you
+ can #include <zlib.h>, it's there. The -lz option will probably link to it.
+
+15. I have a question about OttoPDF.
+
+ We are not the authors of OttoPDF. The real author is on the OttoPDF web
+ site: Joel Hainley, jhainley@myndkryme.com.
+
+16. Can zlib decode Flate data in an Adobe PDF file?
+
+ Yes. See http://www.fastio.com/ (ClibPDF), or http://www.pdflib.com/ .
+ To modify PDF forms, see http://sourceforge.net/projects/acroformtool/ .
+
+17. Why am I getting this "register_frame_info not found" error on Solaris?
+
+ After installing zlib 1.1.4 on Solaris 2.6, running applications using zlib
+ generates an error such as:
+
+ ld.so.1: rpm: fatal: relocation error: file /usr/local/lib/libz.so:
+ symbol __register_frame_info: referenced symbol not found
+
+ The symbol __register_frame_info is not part of zlib, it is generated by
+ the C compiler (cc or gcc). You must recompile applications using zlib
+ which have this problem. This problem is specific to Solaris. See
+ http://www.sunfreeware.com for Solaris versions of zlib and applications
+ using zlib.
+
+18. Why does gzip give an error on a file I make with compress/deflate?
+
+ The compress and deflate functions produce data in the zlib format, which
+ is different and incompatible with the gzip format. The gz* functions in
+ zlib on the other hand use the gzip format. Both the zlib and gzip
+ formats use the same compressed data format internally, but have different
+ headers and trailers around the compressed data.
+
+19. Ok, so why are there two different formats?
+
+ The gzip format was designed to retain the directory information about
+ a single file, such as the name and last modification date. The zlib
+ format on the other hand was designed for in-memory and communication
+ channel applications, and has a much more compact header and trailer and
+ uses a faster integrity check than gzip.
+
+20. Well that's nice, but how do I make a gzip file in memory?
+
+ You can request that deflate write the gzip format instead of the zlib
+ format using deflateInit2(). You can also request that inflate decode
+ the gzip format using inflateInit2(). Read zlib.h for more details.
+
+21. Is zlib thread-safe?
+
+ Yes. However any library routines that zlib uses and any application-
+ provided memory allocation routines must also be thread-safe. zlib's gz*
+ functions use stdio library routines, and most of zlib's functions use the
+ library memory allocation routines by default. zlib's Init functions allow
+ for the application to provide custom memory allocation routines.
+
+ Of course, you should only operate on any given zlib or gzip stream from a
+ single thread at a time.
+
+22. Can I use zlib in my commercial application?
+
+ Yes. Please read the license in zlib.h.
+
+23. Is zlib under the GNU license?
+
+ No. Please read the license in zlib.h.
+
+24. The license says that altered source versions must be "plainly marked". So
+ what exactly do I need to do to meet that requirement?
+
+ You need to change the ZLIB_VERSION and ZLIB_VERNUM #defines in zlib.h. In
+ particular, the final version number needs to be changed to "f", and an
+ identification string should be appended to ZLIB_VERSION. Version numbers
+ x.x.x.f are reserved for modifications to zlib by others than the zlib
+ maintainers. For example, if the version of the base zlib you are altering
+ is "1.2.3.4", then in zlib.h you should change ZLIB_VERNUM to 0x123f, and
+ ZLIB_VERSION to something like "1.2.3.f-zachary-mods-v3". You can also
+ update the version strings in deflate.c and inftrees.c.
+
+ For altered source distributions, you should also note the origin and
+ nature of the changes in zlib.h, as well as in ChangeLog and README, along
+ with the dates of the alterations. The origin should include at least your
+ name (or your company's name), and an email address to contact for help or
+ issues with the library.
+
+ Note that distributing a compiled zlib library along with zlib.h and
+ zconf.h is also a source distribution, and so you should change
+ ZLIB_VERSION and ZLIB_VERNUM and note the origin and nature of the changes
+ in zlib.h as you would for a full source distribution.
+
+25. Will zlib work on a big-endian or little-endian architecture, and can I
+ exchange compressed data between them?
+
+ Yes and yes.
+
+26. Will zlib work on a 64-bit machine?
+
+ It should. It has been tested on 64-bit machines, and has no dependence
+ on any data types being limited to 32-bits in length. If you have any
+ difficulties, please provide a complete problem report to zlib@gzip.org
+
+27. Will zlib decompress data from the PKWare Data Compression Library?
+
+ No. The PKWare DCL uses a completely different compressed data format
+ than does PKZIP and zlib. However, you can look in zlib's contrib/blast
+ directory for a possible solution to your problem.
+
+28. Can I access data randomly in a compressed stream?
+
+ No, not without some preparation. If when compressing you periodically
+ use Z_FULL_FLUSH, carefully write all the pending data at those points,
+ and keep an index of those locations, then you can start decompression
+ at those points. You have to be careful to not use Z_FULL_FLUSH too
+ often, since it can significantly degrade compression.
+
+29. Does zlib work on MVS, OS/390, CICS, etc.?
+
+ We don't know for sure. We have heard occasional reports of success on
+ these systems. If you do use it on one of these, please provide us with
+ a report, instructions, and patches that we can reference when we get
+ these questions. Thanks.
+
+30. Is there some simpler, easier to read version of inflate I can look at
+ to understand the deflate format?
+
+ First off, you should read RFC 1951. Second, yes. Look in zlib's
+ contrib/puff directory.
+
+31. Does zlib infringe on any patents?
+
+ As far as we know, no. In fact, that was originally the whole point behind
+ zlib. Look here for some more information:
+
+ http://www.gzip.org/#faq11
+
+32. Can zlib work with greater than 4 GB of data?
+
+ Yes. inflate() and deflate() will process any amount of data correctly.
+ Each call of inflate() or deflate() is limited to input and output chunks
+ of the maximum value that can be stored in the compiler's "unsigned int"
+ type, but there is no limit to the number of chunks. Note however that the
+ strm.total_in and strm_total_out counters may be limited to 4 GB. These
+ counters are provided as a convenience and are not used internally by
+ inflate() or deflate(). The application can easily set up its own counters
+ updated after each call of inflate() or deflate() to count beyond 4 GB.
+ compress() and uncompress() may be limited to 4 GB, since they operate in a
+ single call. gzseek() and gztell() may be limited to 4 GB depending on how
+ zlib is compiled. See the zlibCompileFlags() function in zlib.h.
+
+ The word "may" appears several times above since there is a 4 GB limit
+ only if the compiler's "long" type is 32 bits. If the compiler's "long"
+ type is 64 bits, then the limit is 16 exabytes.
+
+33. Does zlib have any security vulnerabilities?
+
+ The only one that we are aware of is potentially in gzprintf(). If zlib
+ is compiled to use sprintf() or vsprintf(), then there is no protection
+ against a buffer overflow of a 4K string space, other than the caller of
+ gzprintf() assuring that the output will not exceed 4K. On the other
+ hand, if zlib is compiled to use snprintf() or vsnprintf(), which should
+ normally be the case, then there is no vulnerability. The ./configure
+ script will display warnings if an insecure variation of sprintf() will
+ be used by gzprintf(). Also the zlibCompileFlags() function will return
+ information on what variant of sprintf() is used by gzprintf().
+
+ If you don't have snprintf() or vsnprintf() and would like one, you can
+ find a portable implementation here:
+
+ http://www.ijs.si/software/snprintf/
+
+ Note that you should be using the most recent version of zlib. Versions
+ 1.1.3 and before were subject to a double-free vulnerability.
+
+34. Is there a Java version of zlib?
+
+ Probably what you want is to use zlib in Java. zlib is already included
+ as part of the Java SDK in the java.util.zip package. If you really want
+ a version of zlib written in the Java language, look on the zlib home
+ page for links: http://www.zlib.org/
+
+35. I get this or that compiler or source-code scanner warning when I crank it
+ up to maximally-pedantic. Can't you guys write proper code?
+
+ Many years ago, we gave up attempting to avoid warnings on every compiler
+ in the universe. It just got to be a waste of time, and some compilers
+ were downright silly. So now, we simply make sure that the code always
+ works.
+
+36. Valgrind (or some similar memory access checker) says that deflate is
+ performing a conditional jump that depends on an uninitialized value.
+ Isn't that a bug?
+
+ No. That is intentional for performance reasons, and the output of
+ deflate is not affected. This only started showing up recently since
+ zlib 1.2.x uses malloc() by default for allocations, whereas earlier
+ versions used calloc(), which zeros out the allocated memory.
+
+37. Will zlib read the (insert any ancient or arcane format here) compressed
+ data format?
+
+ Probably not. Look in the comp.compression FAQ for pointers to various
+ formats and associated software.
+
+38. How can I encrypt/decrypt zip files with zlib?
+
+ zlib doesn't support encryption. The original PKZIP encryption is very weak
+ and can be broken with freely available programs. To get strong encryption,
+ use GnuPG, http://www.gnupg.org/ , which already includes zlib compression.
+ For PKZIP compatible "encryption", look at http://www.info-zip.org/
+
+39. What's the difference between the "gzip" and "deflate" HTTP 1.1 encodings?
+
+ "gzip" is the gzip format, and "deflate" is the zlib format. They should
+ probably have called the second one "zlib" instead to avoid confusion
+ with the raw deflate compressed data format. While the HTTP 1.1 RFC 2616
+ correctly points to the zlib specification in RFC 1950 for the "deflate"
+ transfer encoding, there have been reports of servers and browsers that
+ incorrectly produce or expect raw deflate data per the deflate
+ specficiation in RFC 1951, most notably Microsoft. So even though the
+ "deflate" transfer encoding using the zlib format would be the more
+ efficient approach (and in fact exactly what the zlib format was designed
+ for), using the "gzip" transfer encoding is probably more reliable due to
+ an unfortunate choice of name on the part of the HTTP 1.1 authors.
+
+ Bottom line: use the gzip format for HTTP 1.1 encoding.
+
+40. Does zlib support the new "Deflate64" format introduced by PKWare?
+
+ No. PKWare has apparently decided to keep that format proprietary, since
+ they have not documented it as they have previous compression formats.
+ In any case, the compression improvements are so modest compared to other
+ more modern approaches, that it's not worth the effort to implement.
+
+41. Can you please sign these lengthy legal documents and fax them back to us
+ so that we can use your software in our product?
+
+ No. Go away. Shoo.

+ZLIB DATA COMPRESSION LIBRARY
+
+zlib 1.2.3 is a general purpose data compression library. All the code is
+thread safe. The data format used by the zlib library is described by RFCs
+(Request for Comments) 1950 to 1952 in the files
+http://www.ietf.org/rfc/rfc1950.txt (zlib format), rfc1951.txt (deflate format)
+and rfc1952.txt (gzip format). These documents are also available in other
+formats from ftp://ftp.uu.net/graphics/png/documents/zlib/zdoc-index.html
+
+All functions of the compression library are documented in the file zlib.h
+(volunteer to write man pages welcome, contact zlib@gzip.org). A usage example
+of the library is given in the file example.c which also tests that the library
+is working correctly. Another example is given in the file minigzip.c. The
+compression library itself is composed of all source files except example.c and
+minigzip.c.
+
+To compile all files and run the test program, follow the instructions given at
+the top of Makefile. In short "make test; make install" should work for most
+machines. For Unix: "./configure; make test; make install". For MSDOS, use one
+of the special makefiles such as Makefile.msc. For VMS, use make_vms.com.
+
+Questions about zlib should be sent to <zlib@gzip.org>, or to Gilles Vollant
+<info@winimage.com> for the Windows DLL version. The zlib home page is
+http://www.zlib.org or http://www.gzip.org/zlib/ Before reporting a problem,
+please check this site to verify that you have the latest version of zlib;
+otherwise get the latest version and check whether the problem still exists or
+not.
+
+PLEASE read the zlib FAQ http://www.gzip.org/zlib/zlib_faq.html before asking
+for help.
+
+Mark Nelson <markn@ieee.org> wrote an article about zlib for the Jan. 1997
+issue of Dr. Dobb's Journal; a copy of the article is available in
+http://dogma.net/markn/articles/zlibtool/zlibtool.htm
+
+The changes made in version 1.2.3 are documented in the file ChangeLog.
+
+Unsupported third party contributions are provided in directory "contrib".
+
+A Java implementation of zlib is available in the Java Development Kit
+http://java.sun.com/j2se/1.4.2/docs/api/java/util/zip/package-summary.html
+See the zlib home page http://www.zlib.org for details.
+
+A Perl interface to zlib written by Paul Marquess <pmqs@cpan.org> is in the
+CPAN (Comprehensive Perl Archive Network) sites
+http://www.cpan.org/modules/by-module/Compress/
+
+A Python interface to zlib written by A.M. Kuchling <amk@amk.ca> is
+available in Python 1.5 and later versions, see
+http://www.python.org/doc/lib/module-zlib.html
+
+A zlib binding for TCL written by Andreas Kupries <a.kupries@westend.com> is
+availlable at http://www.oche.de/~akupries/soft/trf/trf_zip.html
+
+An experimental package to read and write files in .zip format, written on top
+of zlib by Gilles Vollant <info@winimage.com>, is available in the
+contrib/minizip directory of zlib.
+
+
+Notes for some targets:
+
+- For Windows DLL versions, please see win32/DLL_FAQ.txt
+
+- For 64-bit Irix, deflate.c must be compiled without any optimization. With
+ -O, one libpng test fails. The test works in 32 bit mode (with the -n32
+ compiler flag). The compiler bug has been reported to SGI.
+
+- zlib doesn't work with gcc 2.6.3 on a DEC 3000/300LX under OSF/1 2.1 it works
+ when compiled with cc.
+
+- On Digital Unix 4.0D (formely OSF/1) on AlphaServer, the cc option -std1 is
+ necessary to get gzprintf working correctly. This is done by configure.
+
+- zlib doesn't work on HP-UX 9.05 with some versions of /bin/cc. It works with
+ other compilers. Use "make test" to check your compiler.
+
+- gzdopen is not supported on RISCOS, BEOS and by some Mac compilers.
+
+- For PalmOs, see http://palmzlib.sourceforge.net/
+
+- When building a shared, i.e. dynamic library on Mac OS X, the library must be
+ installed before testing (do "make install" before "make test"), since the
+ library location is specified in the library.
+
+
+Acknowledgments:
+
+ The deflate format used by zlib was defined by Phil Katz. The deflate
+ and zlib specifications were written by L. Peter Deutsch. Thanks to all the
+ people who reported problems and suggested various improvements in zlib;
+ they are too numerous to cite here.

+#
+# To create a shared library, use "configure --shared"; by default a static
+# library is created. If the primitive shared library support provided here
+# does not work, use ftp://prep.ai.mit.edu/pub/gnu/libtool-*.tar.gz
+#
+# To impose specific compiler or flags or install directory, use for example:
+# prefix=$HOME CC=cc CFLAGS="-O4" ./configure
+# or for csh/tcsh users:
+# (setenv prefix $HOME; setenv CC cc; setenv CFLAGS "-O4"; ./configure)
+# LDSHARED is the command to be used to create a shared library
+
+# Incorrect settings of CC or CFLAGS may prevent creating a shared library.

+This is a patched version of zlib modified to use
+Pentium-optimized assembly code in the deflation algorithm. The files
+changed/added by this patch are:
+
+README.586
+match.S
+
+The effectiveness of these modifications is a bit marginal, as the the
+program's bottleneck seems to be mostly L1-cache contention, for which
+there is no real way to work around without rewriting the basic
+algorithm. The speedup on average is around 5-10% (which is generally
+less than the amount of variance between subsequent executions).
+However, when used at level 9 compression, the cache contention can
+drop enough for the assembly version to achieve 10-20% speedup (and
+sometimes more, depending on the amount of overall redundancy in the
+files). Even here, though, cache contention can still be the limiting
+factor, depending on the nature of the program using the zlib library.
+This may also mean that better improvements will be seen on a Pentium
+with MMX, which suffers much less from L1-cache contention, but I have
+not yet verified this.
+
+Note that this code has been tailored for the Pentium in particular,
+and will not perform well on the Pentium Pro (due to the use of a
+partial register in the inner loop).
+
+If you are using an assembler other than GNU as, you will have to
+translate match.S to use your assembler's syntax. (Have fun.)

+ * Here is the inner loop of the function. The function will spend the
+ * majority of its time in this loop, and majority of that time will
+ * be spent in the first ten instructions.
+ *
+ * Within this loop:
+ * %ebx = chainlenscanend - i.e., ((chainlen << 16) | scanend)
+ * %ecx = curmatch
+ * %edx = curmatch & wmask
+ * %esi = windowbestlen - i.e., (window + bestlen)
+ * %edi = prev
+ * %ebp = limit
+ *
+ * Two optimization notes on the choice of instructions:
+ *
+ * The first instruction uses a 16-bit address, which costs an extra,
+ * unpairable cycle. This is cheaper than doing a 32-bit access and
+ * zeroing the high word, due to the 3-cycle misalignment penalty which
+ * would occur half the time. This also turns out to be cheaper than
+ * doing two separate 8-bit accesses, as the memory is so rarely in the
+ * L1 cache.
+ *
+ * The window buffer, however, apparently spends a lot of time in the
+ * cache, and so it is faster to retrieve the word at the end of the
+ * match string with two 8-bit loads. The instructions that test the
+ * word at the beginning of the match string, however, are executed
+ * much less frequently, and there it was cheaper to use 16-bit
+ * instructions, which avoided the necessity of saving off and
+ * subsequently reloading one of the other registers.

-This is a patched version of zlib, modified to use
-Pentium-Pro-optimized assembly code in the deflation algorithm. The

-
-README.686
-match.S
-
-The speedup that this patch provides varies, depending on whether the
-compiler used to build the original version of zlib falls afoul of the
-PPro's speed traps. My own tests show a speedup of around 10-20% at
-the default compression level, and 20-30% using -9, against a version
-compiled using gcc 2.7.2.3. Your mileage may vary.
-
-Note that this code has been tailored for the PPro/PII in particular,
-and will not perform particuarly well on a Pentium.
-
-If you are using an assembler other than GNU as, you will have to
-translate match.S to use your assembler's syntax. (Have fun.)

-Added for zlib 1.1.3:
-
-The patches come from
-http://www.muppetlabs.com/~breadbox/software/assembly.html
-
-To compile zlib with this asm file, copy match.S to the zlib directory
-then do:
-
-CFLAGS="-O3 -DASMV" ./configure
-make OBJA=match.o
-
-
-Update:
-
-I've been ignoring these assembly routines for years, believing that
-gcc's generated code had caught up with it sometime around gcc 2.95
-and the major rearchitecting of the Pentium 4. However, I recently
-learned that, despite what I believed, this code still has some life
-in it. On the Pentium 4 and AMD64 chips, it continues to run about 8%
-faster than the code produced by gcc 4.1.
-
-In acknowledgement of its continuing usefulness, I've altered the
-license to match that of the rest of zlib. Share and Enjoy!

- will raise an exception.

- the internal output buffer is full. All pending output data is flushed
- when the stream is destroyed.

- Compressed data comes from a separate source stream. TDecompressionStream
- is read-only and unidirectional; you can seek forward in the stream, but not
- backwards. The special case of setting the stream position to zero is
- allowed. Seeking forward decompresses data until the requested position in
- the uncompressed data has been reached. Seeking backwards, seeking relative
- to the end of the stream, requesting the size of the stream, and writing to
- the stream will raise an exception.

- The Position property returns the number of bytes of uncompressed data that
- have been read from the stream so far.
-
- The OnProgress event is called each time the internal input buffer of
- compressed data is exhausted and the next block is read from the input stream.

+{ TCompressionStream compresses data on the fly as data is written to it, and
+ stores the compressed data to another stream.
+
+ TCompressionStream is write-only and strictly sequential. Reading from the
+ stream will raise an exception. Using Seek to move the stream pointer
+ will raise an exception.
+
+ Output data is cached internally, written to the output stream only when
+ the internal output buffer is full. All pending output data is flushed
+ when the stream is destroyed.
+
+ The Position property returns the number of uncompressed bytes of
+ data that have been written to the stream so far.
+
+ CompressionRate returns the on-the-fly percentage by which the original
+ data has been compressed: (1 - (CompressedBytes / UncompressedBytes)) * 100
+ If raw data size = 100 and compressed data size = 25, the CompressionRate
+ is 75%
+
+ The OnProgress event is called each time the output buffer is filled and
+ written to the output stream. This is useful for updating a progress
+ indicator when you are writing a large chunk of data to the compression
+ stream in a single call.}

+{ TDecompressionStream decompresses data on the fly as data is read from it.
+
+ Compressed data comes from a separate source stream. TDecompressionStream
+ is read-only and unidirectional; you can seek forward in the stream, but not
+ backwards. The special case of setting the stream position to zero is
+ allowed. Seeking forward decompresses data until the requested position in
+ the uncompressed data has been reached. Seeking backwards, seeking relative
+ to the end of the stream, requesting the size of the stream, and writing to
+ the stream will raise an exception.
+
+ The Position property returns the number of bytes of uncompressed data that
+ have been read from the stream so far.
+
+ The OnProgress event is called each time the internal input buffer of
+ compressed data is exhausted and the next block is read from the input stream.
+ This is useful for updating a progress indicator when you are reading a
+ large chunk of data from the decompression stream in a single call.}

-
-The wrapper includes support for inflating/deflating memory buffers,
-.Net streaming wrappers for the gz streams part of zlib, and wrappers
-for the checksum parts of zlib. See DotZLib/UnitTests.cs for examples.
-
-Directory structure:
---------------------
-
-LICENSE_1_0.txt - License file.
-readme.txt - This file.
-DotZLib.chm - Class library documentation
-DotZLib.build - NAnt build file
-DotZLib.sln - Microsoft Visual Studio 2003 solution file
-
-DotZLib\*.cs - Source files for the class library
-
-Unit tests:
------------
-The file DotZLib/UnitTests.cs contains unit tests for use with NUnit 2.1 or higher.
-To include unit tests in the build, define nunit before building.
-
-
-Build instructions:
--------------------
-
-1. Using Visual Studio.Net 2003:
- Open DotZLib.sln in VS.Net and build from there. Output file (DotZLib.dll)
- will be found ./DotZLib/bin/release or ./DotZLib/bin/debug, depending on
- you are building the release or debug version of the library. Check
- DotZLib/UnitTests.cs for instructions on how to include unit tests in the
- build.
-
-2. Using NAnt:
- Open a command prompt with access to the build environment and run nant
- in the same directory as the DotZLib.build file.
- You can define 2 properties on the nant command-line to control the build:
- debug={true|false} to toggle between release/debug builds (default=true).
- nunit={true|false} to include or esclude unit tests (default=true).
- Also the target clean will remove binaries.
- Output file (DotZLib.dll) will be found in either ./DotZLib/bin/release
- or ./DotZLib/bin/debug, depending on whether you are building the release
- or debug version of the library.
-
- Examples:
- nant -D:debug=false -D:nunit=false
- will build a release mode version of the library without unit tests.
- nant
- will build a debug version of the library with unit tests
- nant clean
- will remove all previously built files.

- *
- * This version (Jan-23-2003) of inflate_fast was coded and tested under
- * GNU/Linux on a pentium 3, using the gcc-3.2 compiler distribution. On that
- * machine, I found that gzip style archives decompressed about 20% faster than
- * the gcc-3.2 -O3 -fomit-frame-pointer compiled version. Your results will
- * depend on how large of a buffer is used for z_stream.next_in & next_out
- * (8K-32K worked best for my 256K cpu cache) and how much overhead there is in
- * stream processing I/O and crc32/addler32. In my case, this routine used
- * 70% of the cpu time and crc32 used 20%.
- *
- * I am confident that this version will work in the general case, but I have
- * not tested a wide variety of datasets or a wide variety of platforms.
- *
- * Jan-24-2003 -- Added -DUSE_MMX define for slightly faster inflating.
- * It should be a runtime flag instead of compile time flag...
- *
- * Jan-26-2003 -- Added runtime check for MMX support with cpuid instruction.
- * With -DUSE_MMX, only MMX code is compiled. With -DNO_MMX, only non-MMX code
- * is compiled. Without either option, runtime detection is enabled. Runtime
- * detection should work on all modern cpus and the recomended algorithm (flip
- * ID bit on eflags and then use the cpuid instruction) is used in many
- * multimedia applications. Tested under win2k with gcc-2.95 and gas-2.12
- * distributed with cygwin3. Compiling with gcc-2.95 -c inffast.S -o
- * inffast.obj generates a COFF object which can then be linked with MSVC++
- * compiled code. Tested under FreeBSD 4.7 with gcc-2.95.
- *
- * Jan-28-2003 -- Tested Athlon XP... MMX mode is slower than no MMX (and
- * slower than compiler generated code). Adjusted cpuid check to use the MMX
- * code only for Pentiums < P4 until I have more data on the P4. Speed
- * improvment is only about 15% on the Athlon when compared with code generated
- * with MSVC++. Not sure yet, but I think the P4 will also be slower using the
- * MMX mode because many of it's x86 ALU instructions execute in .5 cycles and
- * have less latency than MMX ops. Added code to buffer the last 11 bytes of
- * the input stream since the MMX code grabs bits in chunks of 32, which
- * differs from the inffast.c algorithm. I don't think there would have been
- * read overruns where a page boundary was crossed (a segfault), but there
- * could have been overruns when next_in ends on unaligned memory (unintialized
- * memory read).
- *
- * Mar-13-2003 -- P4 MMX is slightly slower than P4 NO_MMX. I created a C
- * version of the non-MMX code so that it doesn't depend on zstrm and zstate
- * structure offsets which are hard coded in this file. This was last tested
- * with zlib-1.2.0 which is currently in beta testing, newer versions of this
- * and inffas86.c can be found at http://www.eetbeetee.com/zlib/ and
- * http://www.charm.net/~christop/zlib/

+ * inffast.S is a hand tuned assembler version of:
+ *
+ * inffast.c -- fast decoding
+ * Copyright (C) 1995-2003 Mark Adler
+ * For conditions of distribution and use, see copyright notice in zlib.h
+ *
+ * Copyright (C) 2003 Chris Anderson <christop@charm.net>
+ * Please use the copyright conditions above.
+ *
+ * This version (Jan-23-2003) of inflate_fast was coded and tested under
+ * GNU/Linux on a pentium 3, using the gcc-3.2 compiler distribution. On that
+ * machine, I found that gzip style archives decompressed about 20% faster than
+ * the gcc-3.2 -O3 -fomit-frame-pointer compiled version. Your results will
+ * depend on how large of a buffer is used for z_stream.next_in & next_out
+ * (8K-32K worked best for my 256K cpu cache) and how much overhead there is in
+ * stream processing I/O and crc32/addler32. In my case, this routine used
+ * 70% of the cpu time and crc32 used 20%.
+ *
+ * I am confident that this version will work in the general case, but I have
+ * not tested a wide variety of datasets or a wide variety of platforms.
+ *
+ * Jan-24-2003 -- Added -DUSE_MMX define for slightly faster inflating.
+ * It should be a runtime flag instead of compile time flag...
+ *
+ * Jan-26-2003 -- Added runtime check for MMX support with cpuid instruction.
+ * With -DUSE_MMX, only MMX code is compiled. With -DNO_MMX, only non-MMX code
+ * is compiled. Without either option, runtime detection is enabled. Runtime
+ * detection should work on all modern cpus and the recomended algorithm (flip
+ * ID bit on eflags and then use the cpuid instruction) is used in many
+ * multimedia applications. Tested under win2k with gcc-2.95 and gas-2.12
+ * distributed with cygwin3. Compiling with gcc-2.95 -c inffast.S -o
+ * inffast.obj generates a COFF object which can then be linked with MSVC++
+ * compiled code. Tested under FreeBSD 4.7 with gcc-2.95.
+ *
+ * Jan-28-2003 -- Tested Athlon XP... MMX mode is slower than no MMX (and
+ * slower than compiler generated code). Adjusted cpuid check to use the MMX
+ * code only for Pentiums < P4 until I have more data on the P4. Speed
+ * improvment is only about 15% on the Athlon when compared with code generated
+ * with MSVC++. Not sure yet, but I think the P4 will also be slower using the
+ * MMX mode because many of it's x86 ALU instructions execute in .5 cycles and
+ * have less latency than MMX ops. Added code to buffer the last 11 bytes of
+ * the input stream since the MMX code grabs bits in chunks of 32, which
+ * differs from the inffast.c algorithm. I don't think there would have been
+ * read overruns where a page boundary was crossed (a segfault), but there
+ * could have been overruns when next_in ends on unaligned memory (unintialized
+ * memory read).
+ *
+ * Mar-13-2003 -- P4 MMX is slightly slower than P4 NO_MMX. I created a C
+ * version of the non-MMX code so that it doesn't depend on zstrm and zstate
+ * structure offsets which are hard coded in this file. This was last tested
+ * with zlib-1.2.0 which is currently in beta testing, newer versions of this
+ * and inffas86.c can be found at http://www.eetbeetee.com/zlib/ and
+ * http://www.charm.net/~christop/zlib/

- Decode literal, length, and distance codes and write out the resulting
- literal and match bytes until either not enough input or output is
- available, an end-of-block is encountered, or a data error is encountered.
- When large enough input and output buffers are supplied to inflate(), for
- example, a 16K input buffer and a 64K output buffer, more than 95% of the
- inflate execution time is spent in this routine.
-
- Entry assumptions:
-
- state->mode == LEN
- strm->avail_in >= 6
- strm->avail_out >= 258
- start >= strm->avail_out
- state->bits < 8
-
- On return, state->mode is one of:
-
- LEN -- ran out of enough output space or enough available input
- TYPE -- reached end of block code, inflate() to interpret next block
- BAD -- error in block data
-
- Notes:
-
- - The maximum input bits used by a length/distance pair is 15 bits for the
- length code, 5 bits for the length extra, 15 bits for the distance code,
- and 13 bits for the distance extra. This totals 48 bits, or six bytes.
- Therefore if strm->avail_in >= 6, then there is enough input to avoid
- checking for available input while decoding.
-
- - The maximum bytes that a single length/distance pair can output is 258
- bytes, which is the maximum length that can be coded. inflate_fast()
- requires strm->avail_out >= 258 for each loop to avoid checking for
- output space.

+; Copyright (C) 1995-1996 Jean-loup Gailly and Gilles Vollant.
+; File written by Gilles Vollant, by modifiying the longest_match
+; from Jean-loup Gailly in deflate.c
+;
+; http://www.zlib.net
+; http://www.winimage.com/zLibDll

+; ml.exe is also distributed in http://www.masm32.com/masmdl.htm
+; and in VC++2003 toolkit at http://msdn.microsoft.com/visualc/vctoolkit2003/
+;
+; this file contain two implementation of longest_match
+;
+; longest_match_7fff : written 1996 by Gilles Vollant optimized for
+; first Pentium. Assume s->w_mask == 0x7fff
+; longest_match_686 : written by Brian raiter (1998), optimized for Pentium Pro
+;
+; for using an seembly version of longest_match, you need define ASMV in project
+; There is two way in using gvmat32.asm
+;
+; A) Suggested method
+; if you want include both longest_match_7fff and longest_match_686
+; compile the asm file running
+; ml /coff /Zi /Flgvmat32.lst /c gvmat32.asm
+; and include gvmat32c.c in your project
+; if you have an old cpu (386,486 or first Pentium) and s->w_mask==0x7fff,
+; longest_match_7fff will be used
+; if you have a more modern CPU (Pentium Pro, II and higher)
+; longest_match_686 will be used
+; on old cpu with s->w_mask!=0x7fff, longest_match_686 will be used,
+; but this is not a sitation you'll find often
+;
+; B) Alternative
+; if you are not interresed in old cpu performance and want the smaller
+; binaries possible
+;
+; compile the asm file running
+; ml /coff /Zi /c /Flgvmat32.lst /DNOOLDPENTIUMCODE gvmat32.asm
+; and do not include gvmat32c.c in your project (ou define also
+; NOOLDPENTIUMCODE)
+;
+; note : as I known, longest_match_686 is very faster than longest_match_7fff
+; on pentium Pro/II/III, faster (but less) in P4, but it seem
+; longest_match_7fff can be faster (very very litte) on AMD Athlon64/K8
+;

+Building instructions for the DLL versions of Zlib 1.2.3
+========================================================
+
+This directory contains projects that build zlib and minizip using
+Microsoft Visual C++ 7.0/7.1, and Visual C++ .
+
+You don't need to build these projects yourself. You can download the
+binaries from:
+ http://www.winimage.com/zLibDll
+
+More information can be found at this site.
+
+
+Build instructions for Visual Studio 7.x (32 bits)
+--------------------------------------------------
+- Uncompress current zlib, including all contrib/* files
+- Download the crtdll library from
+ http://www.winimage.com/zLibDll/crtdll.zip
+ Unzip crtdll.zip to extract crtdll.lib on contrib\vstudio\vc7.
+- Open contrib\vstudio\vc7\zlibvc.sln with Microsoft Visual C++ 7.x
+ (Visual Studio .Net 2002 or 2003).
+
+Build instructions for Visual Studio 2005 (32 bits or 64 bits)
+--------------------------------------------------------------
+- Uncompress current zlib, including all contrib/* files
+- For 32 bits only: download the crtdll library from
+ http://www.winimage.com/zLibDll/crtdll.zip
+ Unzip crtdll.zip to extract crtdll.lib on contrib\vstudio\vc8.
+- Open contrib\vstudio\vc8\zlibvc.sln with Microsoft Visual C++ 8.0
+
+Build instructions for Visual Studio 2005 64 bits, PSDK compiler
+----------------------------------------------------------------
+at the time of writing this text file, Visual Studio 2005 (and
+ Microsoft Visual C++ 8.0) is on the beta 2 stage.
+Using you can get the free 64 bits compiler from Platform SDK,
+ which is NOT a beta, and compile using the Visual studio 2005 IDE
+see http://www.winimage.com/misc/sdk64onvs2005/ for instruction
+
+- Uncompress current zlib, including all contrib/* files
+- start Visual Studio 2005 from a platform SDK command prompt, using
+ the /useenv switch
+- Open contrib\vstudio\vc8\zlibvc.sln with Microsoft Visual C++ 8.0
+
+
+Important
+---------
+- To use zlibwapi.dll in your application, you must define the
+ macro ZLIB_WINAPI when compiling your application's source files.
+
+
+Additional notes
+----------------
+- This DLL, named zlibwapi.dll, is compatible to the old zlib.dll built
+ by Gilles Vollant from the zlib 1.1.x sources, and distributed at
+ http://www.winimage.com/zLibDll
+ It uses the WINAPI calling convention for the exported functions, and
+ includes the minizip functionality. If your application needs that
+ particular build of zlib.dll, you can rename zlibwapi.dll to zlib.dll.
+
+- The new DLL was renamed because there exist several incompatible
+ versions of zlib.dll on the Internet.
+
+- There is also an official DLL build of zlib, named zlib1.dll. This one
+ is exporting the functions using the CDECL convention. See the file
+ win32\DLL_FAQ.txt found in this zlib distribution.
+
+- There used to be a ZLIB_DLL macro in zlib 1.1.x, but now this symbol
+ has a slightly different effect. To avoid compatibility problems, do
+ not define it here.
+

-The first thing we do is to initialize the <em>zlib</em> state for compression using
-<tt>deflateInit()</tt>. This must be done before the first use of <tt>deflate()</tt>.
-The <tt>zalloc</tt>, <tt>zfree</tt>, and <tt>opaque</tt> fields in the <tt>strm</tt>
-structure must be initialized before calling <tt>deflateInit()</tt>. Here they are
-set to the <em>zlib</em> constant <tt>Z_NULL</tt> to request that <em>zlib</em> use
-the default memory allocation routines. An application may also choose to provide
-custom memory allocation routines here. <tt>deflateInit()</tt> will allocate on the
-order of 256K bytes for the internal state.
-(See <a href="zlib_tech.html"><em>zlib Technical Details</em></a>.)
-<p>
-<tt>deflateInit()</tt> is called with a pointer to the structure to be initialized and
-the compression level, which is an integer in the range of -1 to 9. Lower compression
-levels result in faster execution, but less compression. Higher levels result in
-greater compression, but slower execution. The <em>zlib</em> constant Z_DEFAULT_COMPRESSION,
-equal to -1,
-provides a good compromise between compression and speed and is equivalent to level 6.
-Level 0 actually does no compression at all, and in fact expands the data slightly to produce
-the <em>zlib</em> format (it is not a byte-for-byte copy of the input).
-More advanced applications of <em>zlib</em>
-may use <tt>deflateInit2()</tt> here instead. Such an application may want to reduce how
-much memory will be used, at some price in compression. Or it may need to request a
-<em>gzip</em> header and trailer instead of a <em>zlib</em> header and trailer, or raw
-encoding with no header or trailer at all.
-<p>
-We must check the return value of <tt>deflateInit()</tt> against the <em>zlib</em> constant
-<tt>Z_OK</tt> to make sure that it was able to
-allocate memory for the internal state, and that the provided arguments were valid.
-<tt>deflateInit()</tt> will also check that the version of <em>zlib</em> that the <tt>zlib.h</tt>
-file came from matches the version of <em>zlib</em> actually linked with the program. This
-is especially important for environments in which <em>zlib</em> is a shared library.
-<p>
-Note that an application can initialize multiple, independent <em>zlib</em> streams, which can
-operate in parallel. The state information maintained in the structure allows the <em>zlib</em>
-routines to be reentrant.

-With the pleasantries out of the way, now we can get down to business. The outer <tt>do</tt>-loop
-reads all of the input file and exits at the bottom of the loop once end-of-file is reached.
-This loop contains the only call of <tt>deflate()</tt>. So we must make sure that all of the
-input data has been processed and that all of the output data has been generated and consumed
-before we fall out of the loop at the bottom.
-<pre><b>
- /* compress until end of file */
- do {
-</b></pre>
-We start off by reading data from the input file. The number of bytes read is put directly
-into <tt>avail_in</tt>, and a pointer to those bytes is put into <tt>next_in</tt>. We also
-check to see if end-of-file on the input has been reached. If we are at the end of file, then <tt>flush</tt> is set to the
-<em>zlib</em> constant <tt>Z_FINISH</tt>, which is later passed to <tt>deflate()</tt> to
-indicate that this is the last chunk of input data to compress. We need to use <tt>feof()</tt>
-to check for end-of-file as opposed to seeing if fewer than <tt>CHUNK</tt> bytes have been read. The
-reason is that if the input file length is an exact multiple of <tt>CHUNK</tt>, we will miss
-the fact that we got to the end-of-file, and not know to tell <tt>deflate()</tt> to finish
-up the compressed stream. If we are not yet at the end of the input, then the <em>zlib</em>
-constant <tt>Z_NO_FLUSH</tt> will be passed to <tt>deflate</tt> to indicate that we are still
-in the middle of the uncompressed data.
-<p>
-If there is an error in reading from the input file, the process is aborted with
-<tt>deflateEnd()</tt> being called to free the allocated <em>zlib</em> state before returning
-the error. We wouldn't want a memory leak, now would we? <tt>deflateEnd()</tt> can be called
-at any time after the state has been initialized. Once that's done, <tt>deflateInit()</tt> (or
-<tt>deflateInit2()</tt>) would have to be called to start a new compression process. There is
-no point here in checking the <tt>deflateEnd()</tt> return code. The deallocation can't fail.

-The inner <tt>do</tt>-loop passes our chunk of input data to <tt>deflate()</tt>, and then
-keeps calling <tt>deflate()</tt> until it is done producing output. Once there is no more
-new output, <tt>deflate()</tt> is guaranteed to have consumed all of the input, i.e.,
-<tt>avail_in</tt> will be zero.
-<pre><b>
- /* run deflate() on input until output buffer not full, finish
- compression if all of source has been read in */
- do {
-</b></pre>
-Output space is provided to <tt>deflate()</tt> by setting <tt>avail_out</tt> to the number
-of available output bytes and <tt>next_out</tt> to a pointer to that space.
-<pre><b>
- strm.avail_out = CHUNK;
- strm.next_out = out;
-</b></pre>
-Now we call the compression engine itself, <tt>deflate()</tt>. It takes as many of the
-<tt>avail_in</tt> bytes at <tt>next_in</tt> as it can process, and writes as many as
-<tt>avail_out</tt> bytes to <tt>next_out</tt>. Those counters and pointers are then
-updated past the input data consumed and the output data written. It is the amount of
-output space available that may limit how much input is consumed.
-Hence the inner loop to make sure that
-all of the input is consumed by providing more output space each time. Since <tt>avail_in</tt>
-and <tt>next_in</tt> are updated by <tt>deflate()</tt>, we don't have to mess with those
-between <tt>deflate()</tt> calls until it's all used up.
-<p>
-The parameters to <tt>deflate()</tt> are a pointer to the <tt>strm</tt> structure containing
-the input and output information and the internal compression engine state, and a parameter
-indicating whether and how to flush data to the output. Normally <tt>deflate</tt> will consume
-several K bytes of input data before producing any output (except for the header), in order
-to accumulate statistics on the data for optimum compression. It will then put out a burst of
-compressed data, and proceed to consume more input before the next burst. Eventually,
-<tt>deflate()</tt>
-must be told to terminate the stream, complete the compression with provided input data, and
-write out the trailer check value. <tt>deflate()</tt> will continue to compress normally as long
-as the flush parameter is <tt>Z_NO_FLUSH</tt>. Once the <tt>Z_FINISH</tt> parameter is provided,
-<tt>deflate()</tt> will begin to complete the compressed output stream. However depending on how
-much output space is provided, <tt>deflate()</tt> may have to be called several times until it
-has provided the complete compressed stream, even after it has consumed all of the input. The flush
-parameter must continue to be <tt>Z_FINISH</tt> for those subsequent calls.
-<p>
-There are other values of the flush parameter that are used in more advanced applications. You can
-force <tt>deflate()</tt> to produce a burst of output that encodes all of the input data provided
-so far, even if it wouldn't have otherwise, for example to control data latency on a link with
-compressed data. You can also ask that <tt>deflate()</tt> do that as well as erase any history up to
-that point so that what follows can be decompressed independently, for example for random access
-applications. Both requests will degrade compression by an amount depending on how often such
-requests are made.
-<p>
-<tt>deflate()</tt> has a return value that can indicate errors, yet we do not check it here. Why
-not? Well, it turns out that <tt>deflate()</tt> can do no wrong here. Let's go through
-<tt>deflate()</tt>'s return values and dispense with them one by one. The possible values are
-<tt>Z_OK</tt>, <tt>Z_STREAM_END</tt>, <tt>Z_STREAM_ERROR</tt>, or <tt>Z_BUF_ERROR</tt>. <tt>Z_OK</tt>
-is, well, ok. <tt>Z_STREAM_END</tt> is also ok and will be returned for the last call of
-<tt>deflate()</tt>. This is already guaranteed by calling <tt>deflate()</tt> with <tt>Z_FINISH</tt>
-until it has no more output. <tt>Z_STREAM_ERROR</tt> is only possible if the stream is not
-initialized properly, but we did initialize it properly. There is no harm in checking for
-<tt>Z_STREAM_ERROR</tt> here, for example to check for the possibility that some
-other part of the application inadvertently clobbered the memory containing the <em>zlib</em> state.
-<tt>Z_BUF_ERROR</tt> will be explained further below, but
-suffice it to say that this is simply an indication that <tt>deflate()</tt> could not consume
-more input or produce more output. <tt>deflate()</tt> can be called again with more output space
-or more available input, which it will be in this code.
-<pre><b>
- ret = deflate(&strm, flush); /* no bad return value */
- assert(ret != Z_STREAM_ERROR); /* state not clobbered */
-</b></pre>
-Now we compute how much output <tt>deflate()</tt> provided on the last call, which is the
-difference between how much space was provided before the call, and how much output space
-is still available after the call. Then that data, if any, is written to the output file.
-We can then reuse the output buffer for the next call of <tt>deflate()</tt>. Again if there
-is a file i/o error, we call <tt>deflateEnd()</tt> before returning to avoid a memory leak.
-<pre><b>
- have = CHUNK - strm.avail_out;
- if (fwrite(out, 1, have, dest) != have || ferror(dest)) {
- (void)deflateEnd(&strm);
- return Z_ERRNO;
- }
-</b></pre>
-The inner <tt>do</tt>-loop is repeated until the last <tt>deflate()</tt> call fails to fill the
-provided output buffer. Then we know that <tt>deflate()</tt> has done as much as it can with
-the provided input, and that all of that input has been consumed. We can then fall out of this
-loop and reuse the input buffer.
-<p>
-The way we tell that <tt>deflate()</tt> has no more output is by seeing that it did not fill
-the output buffer, leaving <tt>avail_out</tt> greater than zero. However suppose that
-<tt>deflate()</tt> has no more output, but just so happened to exactly fill the output buffer!
-<tt>avail_out</tt> is zero, and we can't tell that <tt>deflate()</tt> has done all it can.
-As far as we know, <tt>deflate()</tt>
-has more output for us. So we call it again. But now <tt>deflate()</tt> produces no output
-at all, and <tt>avail_out</tt> remains unchanged as <tt>CHUNK</tt>. That <tt>deflate()</tt> call
-wasn't able to do anything, either consume input or produce output, and so it returns
-<tt>Z_BUF_ERROR</tt>. (See, I told you I'd cover this later.) However this is not a problem at
-all. Now we finally have the desired indication that <tt>deflate()</tt> is really done,
-and so we drop out of the inner loop to provide more input to <tt>deflate()</tt>.
-<p>
-With <tt>flush</tt> set to <tt>Z_FINISH</tt>, this final set of <tt>deflate()</tt> calls will
-complete the output stream. Once that is done, subsequent calls of <tt>deflate()</tt> would return
-<tt>Z_STREAM_ERROR</tt> if the flush parameter is not <tt>Z_FINISH</tt>, and do no more processing
-until the state is reinitialized.
-<p>
-Some applications of <em>zlib</em> have two loops that call <tt>deflate()</tt>
-instead of the single inner loop we have here. The first loop would call
-without flushing and feed all of the data to <tt>deflate()</tt>. The second loop would call
-<tt>deflate()</tt> with no more
-data and the <tt>Z_FINISH</tt> parameter to complete the process. As you can see from this
-example, that can be avoided by simply keeping track of the current flush state.
-<pre><b>
- } while (strm.avail_out == 0);
- assert(strm.avail_in == 0); /* all input will be used */
-</b></pre><!-- -->
-Now we check to see if we have already processed all of the input file. That information was
-saved in the <tt>flush</tt> variable, so we see if that was set to <tt>Z_FINISH</tt>. If so,
-then we're done and we fall out of the outer loop. We're guaranteed to get <tt>Z_STREAM_END</tt>
-from the last <tt>deflate()</tt> call, since we ran it until the last chunk of input was
-consumed and all of the output was generated.
-<pre><b>
- /* done when last data in file processed */
- } while (flush != Z_FINISH);
- assert(ret == Z_STREAM_END); /* stream will be complete */
-</b></pre><!-- -->
-The process is complete, but we still need to deallocate the state to avoid a memory leak
-(or rather more like a memory hemorrhage if you didn't do this). Then
-finally we can return with a happy return value.
-<pre><b>
- /* clean up and return */
- (void)deflateEnd(&strm);

-(up through versions 1.2.x), the method-dependent memory allocations are deferred to the first call of

+The first thing we do is to initialize the <em>zlib</em> state for compression using
+<tt>deflateInit()</tt>. This must be done before the first use of <tt>deflate()</tt>.
+The <tt>zalloc</tt>, <tt>zfree</tt>, and <tt>opaque</tt> fields in the <tt>strm</tt>
+structure must be initialized before calling <tt>deflateInit()</tt>. Here they are
+set to the <em>zlib</em> constant <tt>Z_NULL</tt> to request that <em>zlib</em> use
+the default memory allocation routines. An application may also choose to provide
+custom memory allocation routines here. <tt>deflateInit()</tt> will allocate on the
+order of 256K bytes for the internal state.
+(See <a href="zlib_tech.html"><em>zlib Technical Details</em></a>.)
+<p>
+<tt>deflateInit()</tt> is called with a pointer to the structure to be initialized and
+the compression level, which is an integer in the range of -1 to 9. Lower compression
+levels result in faster execution, but less compression. Higher levels result in
+greater compression, but slower execution. The <em>zlib</em> constant Z_DEFAULT_COMPRESSION,
+equal to -1,
+provides a good compromise between compression and speed and is equivalent to level 6.
+Level 0 actually does no compression at all, and in fact expands the data slightly to produce
+the <em>zlib</em> format (it is not a byte-for-byte copy of the input).
+More advanced applications of <em>zlib</em>
+may use <tt>deflateInit2()</tt> here instead. Such an application may want to reduce how
+much memory will be used, at some price in compression. Or it may need to request a
+<em>gzip</em> header and trailer instead of a <em>zlib</em> header and trailer, or raw
+encoding with no header or trailer at all.
+<p>
+We must check the return value of <tt>deflateInit()</tt> against the <em>zlib</em> constant
+<tt>Z_OK</tt> to make sure that it was able to
+allocate memory for the internal state, and that the provided arguments were valid.
+<tt>deflateInit()</tt> will also check that the version of <em>zlib</em> that the <tt>zlib.h</tt>
+file came from matches the version of <em>zlib</em> actually linked with the program. This
+is especially important for environments in which <em>zlib</em> is a shared library.
+<p>
+Note that an application can initialize multiple, independent <em>zlib</em> streams, which can
+operate in parallel. The state information maintained in the structure allows the <em>zlib</em>
+routines to be reentrant.

+With the pleasantries out of the way, now we can get down to business. The outer <tt>do</tt>-loop
+reads all of the input file and exits at the bottom of the loop once end-of-file is reached.
+This loop contains the only call of <tt>deflate()</tt>. So we must make sure that all of the
+input data has been processed and that all of the output data has been generated and consumed
+before we fall out of the loop at the bottom.
+<pre><b>
+ /* compress until end of file */
+ do {
+</b></pre>
+We start off by reading data from the input file. The number of bytes read is put directly
+into <tt>avail_in</tt>, and a pointer to those bytes is put into <tt>next_in</tt>. We also
+check to see if end-of-file on the input has been reached. If we are at the end of file, then <tt>flush</tt> is set to the
+<em>zlib</em> constant <tt>Z_FINISH</tt>, which is later passed to <tt>deflate()</tt> to
+indicate that this is the last chunk of input data to compress. We need to use <tt>feof()</tt>
+to check for end-of-file as opposed to seeing if fewer than <tt>CHUNK</tt> bytes have been read. The
+reason is that if the input file length is an exact multiple of <tt>CHUNK</tt>, we will miss
+the fact that we got to the end-of-file, and not know to tell <tt>deflate()</tt> to finish
+up the compressed stream. If we are not yet at the end of the input, then the <em>zlib</em>
+constant <tt>Z_NO_FLUSH</tt> will be passed to <tt>deflate</tt> to indicate that we are still
+in the middle of the uncompressed data.
+<p>
+If there is an error in reading from the input file, the process is aborted with
+<tt>deflateEnd()</tt> being called to free the allocated <em>zlib</em> state before returning
+the error. We wouldn't want a memory leak, now would we? <tt>deflateEnd()</tt> can be called
+at any time after the state has been initialized. Once that's done, <tt>deflateInit()</tt> (or
+<tt>deflateInit2()</tt>) would have to be called to start a new compression process. There is
+no point here in checking the <tt>deflateEnd()</tt> return code. The deallocation can't fail.

+The inner <tt>do</tt>-loop passes our chunk of input data to <tt>deflate()</tt>, and then
+keeps calling <tt>deflate()</tt> until it is done producing output. Once there is no more
+new output, <tt>deflate()</tt> is guaranteed to have consumed all of the input, i.e.,
+<tt>avail_in</tt> will be zero.

+ /* run deflate() on input until output buffer not full, finish

+Output space is provided to <tt>deflate()</tt> by setting <tt>avail_out</tt> to the number
+of available output bytes and <tt>next_out</tt> to a pointer to that space.
+<pre><b>
+ strm.avail_out = CHUNK;
+ strm.next_out = out;
+</b></pre>
+Now we call the compression engine itself, <tt>deflate()</tt>. It takes as many of the
+<tt>avail_in</tt> bytes at <tt>next_in</tt> as it can process, and writes as many as
+<tt>avail_out</tt> bytes to <tt>next_out</tt>. Those counters and pointers are then
+updated past the input data consumed and the output data written. It is the amount of
+output space available that may limit how much input is consumed.
+Hence the inner loop to make sure that
+all of the input is consumed by providing more output space each time. Since <tt>avail_in</tt>
+and <tt>next_in</tt> are updated by <tt>deflate()</tt>, we don't have to mess with those
+between <tt>deflate()</tt> calls until it's all used up.
+<p>
+The parameters to <tt>deflate()</tt> are a pointer to the <tt>strm</tt> structure containing
+the input and output information and the internal compression engine state, and a parameter
+indicating whether and how to flush data to the output. Normally <tt>deflate</tt> will consume
+several K bytes of input data before producing any output (except for the header), in order
+to accumulate statistics on the data for optimum compression. It will then put out a burst of
+compressed data, and proceed to consume more input before the next burst. Eventually,
+<tt>deflate()</tt>
+must be told to terminate the stream, complete the compression with provided input data, and
+write out the trailer check value. <tt>deflate()</tt> will continue to compress normally as long
+as the flush parameter is <tt>Z_NO_FLUSH</tt>. Once the <tt>Z_FINISH</tt> parameter is provided,
+<tt>deflate()</tt> will begin to complete the compressed output stream. However depending on how
+much output space is provided, <tt>deflate()</tt> may have to be called several times until it
+has provided the complete compressed stream, even after it has consumed all of the input. The flush
+parameter must continue to be <tt>Z_FINISH</tt> for those subsequent calls.
+<p>
+There are other values of the flush parameter that are used in more advanced applications. You can
+force <tt>deflate()</tt> to produce a burst of output that encodes all of the input data provided
+so far, even if it wouldn't have otherwise, for example to control data latency on a link with
+compressed data. You can also ask that <tt>deflate()</tt> do that as well as erase any history up to
+that point so that what follows can be decompressed independently, for example for random access
+applications. Both requests will degrade compression by an amount depending on how often such
+requests are made.
+<p>
+<tt>deflate()</tt> has a return value that can indicate errors, yet we do not check it here. Why
+not? Well, it turns out that <tt>deflate()</tt> can do no wrong here. Let's go through
+<tt>deflate()</tt>'s return values and dispense with them one by one. The possible values are
+<tt>Z_OK</tt>, <tt>Z_STREAM_END</tt>, <tt>Z_STREAM_ERROR</tt>, or <tt>Z_BUF_ERROR</tt>. <tt>Z_OK</tt>
+is, well, ok. <tt>Z_STREAM_END</tt> is also ok and will be returned for the last call of
+<tt>deflate()</tt>. This is already guaranteed by calling <tt>deflate()</tt> with <tt>Z_FINISH</tt>
+until it has no more output. <tt>Z_STREAM_ERROR</tt> is only possible if the stream is not
+initialized properly, but we did initialize it properly. There is no harm in checking for
+<tt>Z_STREAM_ERROR</tt> here, for example to check for the possibility that some
+other part of the application inadvertently clobbered the memory containing the <em>zlib</em> state.
+<tt>Z_BUF_ERROR</tt> will be explained further below, but
+suffice it to say that this is simply an indication that <tt>deflate()</tt> could not consume
+more input or produce more output. <tt>deflate()</tt> can be called again with more output space
+or more available input, which it will be in this code.
+<pre><b>
+ ret = deflate(&strm, flush); /* no bad return value */
+ assert(ret != Z_STREAM_ERROR); /* state not clobbered */
+</b></pre>
+Now we compute how much output <tt>deflate()</tt> provided on the last call, which is the
+difference between how much space was provided before the call, and how much output space
+is still available after the call. Then that data, if any, is written to the output file.
+We can then reuse the output buffer for the next call of <tt>deflate()</tt>. Again if there
+is a file i/o error, we call <tt>deflateEnd()</tt> before returning to avoid a memory leak.

+</b></pre>
+The inner <tt>do</tt>-loop is repeated until the last <tt>deflate()</tt> call fails to fill the
+provided output buffer. Then we know that <tt>deflate()</tt> has done as much as it can with
+the provided input, and that all of that input has been consumed. We can then fall out of this
+loop and reuse the input buffer.
+<p>
+The way we tell that <tt>deflate()</tt> has no more output is by seeing that it did not fill
+the output buffer, leaving <tt>avail_out</tt> greater than zero. However suppose that
+<tt>deflate()</tt> has no more output, but just so happened to exactly fill the output buffer!
+<tt>avail_out</tt> is zero, and we can't tell that <tt>deflate()</tt> has done all it can.
+As far as we know, <tt>deflate()</tt>
+has more output for us. So we call it again. But now <tt>deflate()</tt> produces no output
+at all, and <tt>avail_out</tt> remains unchanged as <tt>CHUNK</tt>. That <tt>deflate()</tt> call
+wasn't able to do anything, either consume input or produce output, and so it returns
+<tt>Z_BUF_ERROR</tt>. (See, I told you I'd cover this later.) However this is not a problem at
+all. Now we finally have the desired indication that <tt>deflate()</tt> is really done,
+and so we drop out of the inner loop to provide more input to <tt>deflate()</tt>.
+<p>
+With <tt>flush</tt> set to <tt>Z_FINISH</tt>, this final set of <tt>deflate()</tt> calls will
+complete the output stream. Once that is done, subsequent calls of <tt>deflate()</tt> would return
+<tt>Z_STREAM_ERROR</tt> if the flush parameter is not <tt>Z_FINISH</tt>, and do no more processing
+until the state is reinitialized.
+<p>
+Some applications of <em>zlib</em> have two loops that call <tt>deflate()</tt>
+instead of the single inner loop we have here. The first loop would call
+without flushing and feed all of the data to <tt>deflate()</tt>. The second loop would call
+<tt>deflate()</tt> with no more
+data and the <tt>Z_FINISH</tt> parameter to complete the process. As you can see from this
+example, that can be avoided by simply keeping track of the current flush state.
+<pre><b>
+ } while (strm.avail_out == 0);
+ assert(strm.avail_in == 0); /* all input will be used */
+</b></pre><!-- -->
+Now we check to see if we have already processed all of the input file. That information was
+saved in the <tt>flush</tt> variable, so we see if that was set to <tt>Z_FINISH</tt>. If so,
+then we're done and we fall out of the outer loop. We're guaranteed to get <tt>Z_STREAM_END</tt>
+from the last <tt>deflate()</tt> call, since we ran it until the last chunk of input was
+consumed and all of the output was generated.
+<pre><b>
+ /* done when last data in file processed */
+ } while (flush != Z_FINISH);
+ assert(ret == Z_STREAM_END); /* stream will be complete */
+</b></pre><!-- -->
+The process is complete, but we still need to deallocate the state to avoid a memory leak
+(or rather more like a memory hemorrhage if you didn't do this). Then
+finally we can return with a happy return value.
+<pre><b>
+ /* clean up and return */
+ (void)deflateEnd(&strm);
+ return Z_OK;
+}
+</b></pre><!-- -->
+Now we do the same thing for decompression in the <tt>inf()</tt> routine. <tt>inf()</tt>
+decompresses what is hopefully a valid <em>zlib</em> stream from the input file and writes the
+uncompressed data to the output file. Much of the discussion above for <tt>def()</tt>
+applies to <tt>inf()</tt> as well, so the discussion here will focus on the differences between
+the two.
+<pre><b>
+/* Decompress from file source to file dest until stream ends or EOF.
+ inf() returns Z_OK on success, Z_MEM_ERROR if memory could not be
+ allocated for processing, Z_DATA_ERROR if the deflate data is
+ invalid or incomplete, Z_VERSION_ERROR if the version of zlib.h and
+ the version of the library linked do not match, or Z_ERRNO if there
+ is an error reading or writing the files. */
+int inf(FILE *source, FILE *dest)
+{
+</b></pre>
+The local variables have the same functionality as they do for <tt>def()</tt>. The
+only difference is that there is no <tt>flush</tt> variable, since <tt>inflate()</tt>
+can tell from the <em>zlib</em> stream itself when the stream is complete.
+<pre><b>
+ int ret;
+ unsigned have;
+ z_stream strm;
+ char in[CHUNK];
+ char out[CHUNK];
+</b></pre><!-- -->
+The initialization of the state is the same, except that there is no compression level,
+of course, and two more elements of the structure are initialized. <tt>avail_in</tt>
+and <tt>next_in</tt> must be initialized before calling <tt>inflateInit()</tt>. This
+is because the application has the option to provide the start of the zlib stream in
+order for <tt>inflateInit()</tt> to have access to information about the compression
+method to aid in memory allocation. In the current implementation of <em>zlib</em>
+(up through versions 1.2.x), the method-dependent memory allocations are deferred to the first call of
+<tt>inflate()</tt> anyway. However those fields must be initialized since later versions
+of <em>zlib</em> that provide more compression methods may take advantage of this interface.
+In any case, no decompression is performed by <tt>inflateInit()</tt>, so the
+<tt>avail_out</tt> and <tt>next_out</tt> fields do not need to be initialized before calling.
+<p>
+Here <tt>avail_in</tt> is set to zero and <tt>next_in</tt> is set to <tt>Z_NULL</tt> to
+indicate that no input data is being provided.
+<pre><b>
+ /* allocate inflate state */
+ strm.zalloc = Z_NULL;
+ strm.zfree = Z_NULL;
+ strm.opaque = Z_NULL;
+ strm.avail_in = 0;
+ strm.next_in = Z_NULL;
+ ret = inflateInit(&strm);
+ if (ret != Z_OK)
+ return ret;
+</b></pre><!-- -->
+The outer <tt>do</tt>-loop decompresses input until <tt>inflate()</tt> indicates
+that it has reached the end of the compressed data and has produced all of the uncompressed
+output. This is in contrast to <tt>def()</tt> which processes all of the input file.
+If end-of-file is reached before the compressed data self-terminates, then the compressed
+data is incomplete and an error is returned.
+<pre><b>
+ /* decompress until deflate stream ends or end of file */
+ do {
+</b></pre>
+We read input data and set the <tt>strm</tt> structure accordingly. If we've reached the
+end of the input file, then we leave the outer loop and report an error, since the
+compressed data is incomplete. Note that we may read more data than is eventually consumed
+by <tt>inflate()</tt>, if the input file continues past the <em>zlib</em> stream.
+For applications where <em>zlib</em> streams are embedded in other data, this routine would
+need to be modified to return the unused data, or at least indicate how much of the input
+data was not used, so the application would know where to pick up after the <em>zlib</em> stream.
+<pre><b>
+ strm.avail_in = fread(in, 1, CHUNK, source);
+ if (ferror(source)) {
+ (void)inflateEnd(&strm);

+ break;
+ strm.next_in = in;
+</b></pre><!-- -->
+The inner <tt>do</tt>-loop has the same function it did in <tt>def()</tt>, which is to
+keep calling <tt>inflate()</tt> until has generated all of the output it can with the
+provided input.
+<pre><b>
+ /* run inflate() on input until output buffer not full */
+ do {
+</b></pre>
+Just like in <tt>def()</tt>, the same output space is provided for each call of <tt>inflate()</tt>.
+<pre><b>
+ strm.avail_out = CHUNK;
+ strm.next_out = out;
+</b></pre>
+Now we run the decompression engine itself. There is no need to adjust the flush parameter, since
+the <em>zlib</em> format is self-terminating. The main difference here is that there are
+return values that we need to pay attention to. <tt>Z_DATA_ERROR</tt>
+indicates that <tt>inflate()</tt> detected an error in the <em>zlib</em> compressed data format,
+which means that either the data is not a <em>zlib</em> stream to begin with, or that the data was
+corrupted somewhere along the way since it was compressed. The other error to be processed is
+<tt>Z_MEM_ERROR</tt>, which can occur since memory allocation is deferred until <tt>inflate()</tt>
+needs it, unlike <tt>deflate()</tt>, whose memory is allocated at the start by <tt>deflateInit()</tt>.
+<p>
+Advanced applications may use
+<tt>deflateSetDictionary()</tt> to prime <tt>deflate()</tt> with a set of likely data to improve the
+first 32K or so of compression. This is noted in the <em>zlib</em> header, so <tt>inflate()</tt>
+requests that that dictionary be provided before it can start to decompress. Without the dictionary,
+correct decompression is not possible. For this routine, we have no idea what the dictionary is,
+so the <tt>Z_NEED_DICT</tt> indication is converted to a <tt>Z_DATA_ERROR</tt>.
+<p>
+<tt>inflate()</tt> can also return <tt>Z_STREAM_ERROR</tt>, which should not be possible here,
+but could be checked for as noted above for <tt>def()</tt>. <tt>Z_BUF_ERROR</tt> does not need to be
+checked for here, for the same reasons noted for <tt>def()</tt>. <tt>Z_STREAM_END</tt> will be
+checked for later.
+<pre><b>

+The output of <tt>inflate()</tt> is handled identically to that of <tt>deflate()</tt>.

+</b></pre>
+The inner <tt>do</tt>-loop ends when <tt>inflate()</tt> has no more output as indicated
+by not filling the output buffer, just as for <tt>deflate()</tt>. In this case, we cannot
+assert that <tt>strm.avail_in</tt> will be zero, since the deflate stream may end before the file
+does.
+<pre><b>
+ } while (strm.avail_out == 0);
+</b></pre><!-- -->
+The outer <tt>do</tt>-loop ends when <tt>inflate()</tt> reports that it has reached the
+end of the input <em>zlib</em> stream, has completed the decompression and integrity
+check, and has provided all of the output. This is indicated by the <tt>inflate()</tt>
+return value <tt>Z_STREAM_END</tt>. The inner loop is guaranteed to leave <tt>ret</tt>
+equal to <tt>Z_STREAM_END</tt> if the last chunk of the input file read contained the end
+of the <em>zlib</em> stream. So if the return value is not <tt>Z_STREAM_END</tt>, the
+loop continues to read more input.
+<pre><b>
+ /* done when inflate() says it's done */
+ } while (ret != Z_STREAM_END);
+</b></pre><!-- -->
+At this point, decompression successfully completed, or we broke out of the loop due to no
+more data being available from the input file. If the last <tt>inflate()</tt> return value
+is not <tt>Z_STREAM_END</tt>, then the <em>zlib</em> stream was incomplete and a data error
+is returned. Otherwise, we return with a happy return value. Of course, <tt>inflateEnd()</tt>
+is called first to avoid a memory leak.
+<pre><b>
+ /* clean up and return */
+ (void)inflateEnd(&strm);
+ return ret == Z_STREAM_END ? Z_OK : Z_DATA_ERROR;

+That ends the routines that directly use <em>zlib</em>. The following routines make this
+a command-line program by running data through the above routines from <tt>stdin</tt> to
+<tt>stdout</tt>, and handling any errors reported by <tt>def()</tt> or <tt>inf()</tt>.
+<p>
+<tt>zerr()</tt> is used to interpret the possible error codes from <tt>def()</tt>
+and <tt>inf()</tt>, as detailed in their comments above, and print out an error message.

+This directory contains project files for building zlib under various
+Integrated Development Environments (IDE).
+
+If you wish to submit a new project to this directory, you should comply
+to the following requirements. Otherwise (e.g. if you wish to integrate
+a custom piece of code that changes the zlib interface or its behavior),
+please consider submitting the project to the contrib directory.
+
+
+Requirements
+============
+
+- The project must build zlib using the source files from the official
+ zlib source distribution, exclusively.
+
+- If the project produces redistributable builds (e.g. shared objects
+ or DLL files), these builds must be compatible to those produced by
+ makefiles, if such makefiles exist in the zlib distribution.
+ In particular, if the project produces a DLL build for the Win32
+ platform, this build must comply to the officially-ammended Win32 DLL
+ Application Binary Interface (ABI), described in win32/DLL_FAQ.txt.
+
+- The project may provide additional build targets, which depend on
+ 3rd-party (unofficially-supported) software, present in the contrib
+ directory. For example, it is possible to provide an "ASM build",
+ besides the officially-supported build, and have ASM source files
+ among its dependencies.
+
+- If there are significant differences between the project files created
+ by different versions of an IDE (e.g. Visual C++ 6.0 vs. 7.0), the name
+ of the project directory should contain the version number of the IDE
+ for which the project is intended (e.g. "visualc6" for Visual C++ 6.0,
+ or "visualc7" for Visual C++ 7.0 and 7.1).

+
+This project builds the zlib binaries as follows:
+
+* Win32_DLL_Release\zlib1.dll DLL build
+* Win32_DLL_Debug\zlib1d.dll DLL build (debug version)
+* Win32_DLL_ASM_Release\zlib1.dll DLL build using ASM code
+* Win32_DLL_ASM_Debug\zlib1d.dll DLL build using ASM code (debug version)
+* Win32_LIB_Release\zlib.lib static build
+* Win32_LIB_Debug\zlibd.lib static build (debug version)
+* Win32_LIB_ASM_Release\zlib.lib static build using ASM code
+* Win32_LIB_ASM_Debug\zlibd.lib static build using ASM code (debug version)
+
+
+For more information regarding the DLL builds, please see the DLL FAQ
+in ..\..\win32\DLL_FAQ.txt.
+
+
+To build and test:
+
+1) On the main menu, select "File | Open Workspace".
+ Open "zlib.dsw".
+
+2) Select "Build | Set Active Configuration".
+ Choose the configuration you wish to build.
+
+3) Select "Build | Clean".
+
+4) Select "Build | Build ... (F7)". Ignore warning messages about
+ not being able to find certain include files (e.g. alloc.h).
+
+5) If you built one of the sample programs (example or minigzip),
+ select "Build | Execute ... (Ctrl+F5)".
+
+
+To use:
+
+1) Select "Project | Settings (Alt+F7)".
+ Make note of the configuration names used in your project.
+ Usually, these names are "Win32 Release" and "Win32 Debug".
+
+2) In the Workspace window, select the "FileView" tab.
+ Right-click on the root item "Workspace '...'".
+ Select "Insert Project into Workspace".
+ Switch on the checkbox "Dependency of:", and select the name
+ of your project. Open "zlib.dsp".
+
+3) Select "Build | Configurations".
+ For each configuration of your project:
+ 3.1) Choose the zlib configuration you wish to use.
+ 3.2) Click on "Add".
+ 3.3) Set the new zlib configuration name to the name used by
+ the configuration from the current iteration.
+
+4) Select "Build | Set Active Configuration".
+ Choose the configuration you wish to build.
+
+5) Select "Build | Build ... (F7)".
+
+6) If you built an executable program, select
+ "Build | Execute ... (Ctrl+F5)".
+
+
+Note:
+
+To build the ASM-enabled code, you need Microsoft Assembler
+(ML.EXE). You can get it by downloading and installing the
+latest Processor Pack for Visual C++ 6.0.

- Frequently Asked Questions about zlib
-
-
-If your question is not there, please check the zlib home page
-http://zlib.net/ which may have more recent information.
-The lastest zlib FAQ is at http://zlib.net/zlib_faq.html
-
-
- 1. Is zlib Y2K-compliant?
-
- Yes. zlib doesn't handle dates.
-
- 2. Where can I get a Windows DLL version?
-
- The zlib sources can be compiled without change to produce a DLL. See the
- file win32/DLL_FAQ.txt in the zlib distribution. Pointers to the
- precompiled DLL are found in the zlib web site at http://zlib.net/ .
-
- 3. Where can I get a Visual Basic interface to zlib?
-
- See
- * http://marknelson.us/1997/01/01/zlib-engine/
- * win32/DLL_FAQ.txt in the zlib distribution
-
- 4. compress() returns Z_BUF_ERROR.
-
- Make sure that before the call of compress(), the length of the compressed
- buffer is equal to the available size of the compressed buffer and not
- zero. For Visual Basic, check that this parameter is passed by reference
- ("as any"), not by value ("as long").
-
- 5. deflate() or inflate() returns Z_BUF_ERROR.
-
- Before making the call, make sure that avail_in and avail_out are not zero.
- When setting the parameter flush equal to Z_FINISH, also make sure that
- avail_out is big enough to allow processing all pending input. Note that a
- Z_BUF_ERROR is not fatal--another call to deflate() or inflate() can be
- made with more input or output space. A Z_BUF_ERROR may in fact be
- unavoidable depending on how the functions are used, since it is not
- possible to tell whether or not there is more output pending when
- strm.avail_out returns with zero. See http://zlib.net/zlib_how.html for a
- heavily annotated example.
-
- 6. Where's the zlib documentation (man pages, etc.)?
-
- It's in zlib.h . Examples of zlib usage are in the files test/example.c
- and test/minigzip.c, with more in examples/ .
-
- 7. Why don't you use GNU autoconf or libtool or ...?
-
- Because we would like to keep zlib as a very small and simple package.
- zlib is rather portable and doesn't need much configuration.
-
- 8. I found a bug in zlib.
-
- Most of the time, such problems are due to an incorrect usage of zlib.
- Please try to reproduce the problem with a small program and send the
- corresponding source to us at zlib@gzip.org . Do not send multi-megabyte
- data files without prior agreement.
-
- 9. Why do I get "undefined reference to gzputc"?
-
- If "make test" produces something like
-
- example.o(.text+0x154): undefined reference to `gzputc'
-
- check that you don't have old files libz.* in /usr/lib, /usr/local/lib or
- /usr/X11R6/lib. Remove any old versions, then do "make install".
-
-10. I need a Delphi interface to zlib.
-
- See the contrib/delphi directory in the zlib distribution.
-
-11. Can zlib handle .zip archives?
-
- Not by itself, no. See the directory contrib/minizip in the zlib
- distribution.
-
-12. Can zlib handle .Z files?
-
- No, sorry. You have to spawn an uncompress or gunzip subprocess, or adapt
- the code of uncompress on your own.
-
-13. How can I make a Unix shared library?
-
- By default a shared (and a static) library is built for Unix. So:
-
- make distclean
- ./configure
- make
-
-14. How do I install a shared zlib library on Unix?
-
- After the above, then:
-
- make install
-
- However, many flavors of Unix come with a shared zlib already installed.
- Before going to the trouble of compiling a shared version of zlib and
- trying to install it, you may want to check if it's already there! If you
- can #include <zlib.h>, it's there. The -lz option will probably link to
- it. You can check the version at the top of zlib.h or with the
- ZLIB_VERSION symbol defined in zlib.h .
-
-15. I have a question about OttoPDF.
-
- We are not the authors of OttoPDF. The real author is on the OttoPDF web
- site: Joel Hainley, jhainley@myndkryme.com.
-
-16. Can zlib decode Flate data in an Adobe PDF file?
-
- Yes. See http://www.pdflib.com/ . To modify PDF forms, see
- http://sourceforge.net/projects/acroformtool/ .
-
-17. Why am I getting this "register_frame_info not found" error on Solaris?
-
- After installing zlib 1.1.4 on Solaris 2.6, running applications using zlib
- generates an error such as:
-
- ld.so.1: rpm: fatal: relocation error: file /usr/local/lib/libz.so:
- symbol __register_frame_info: referenced symbol not found
-
- The symbol __register_frame_info is not part of zlib, it is generated by
- the C compiler (cc or gcc). You must recompile applications using zlib
- which have this problem. This problem is specific to Solaris. See
- http://www.sunfreeware.com for Solaris versions of zlib and applications
- using zlib.
-
-18. Why does gzip give an error on a file I make with compress/deflate?
-
- The compress and deflate functions produce data in the zlib format, which
- is different and incompatible with the gzip format. The gz* functions in
- zlib on the other hand use the gzip format. Both the zlib and gzip formats
- use the same compressed data format internally, but have different headers
- and trailers around the compressed data.
-
-19. Ok, so why are there two different formats?
-
- The gzip format was designed to retain the directory information about a
- single file, such as the name and last modification date. The zlib format
- on the other hand was designed for in-memory and communication channel
- applications, and has a much more compact header and trailer and uses a
- faster integrity check than gzip.
-
-20. Well that's nice, but how do I make a gzip file in memory?
-
- You can request that deflate write the gzip format instead of the zlib
- format using deflateInit2(). You can also request that inflate decode the
- gzip format using inflateInit2(). Read zlib.h for more details.
-
-21. Is zlib thread-safe?
-
- Yes. However any library routines that zlib uses and any application-
- provided memory allocation routines must also be thread-safe. zlib's gz*
- functions use stdio library routines, and most of zlib's functions use the
- library memory allocation routines by default. zlib's *Init* functions
- allow for the application to provide custom memory allocation routines.
-
- Of course, you should only operate on any given zlib or gzip stream from a
- single thread at a time.
-
-22. Can I use zlib in my commercial application?
-
- Yes. Please read the license in zlib.h.
-
-23. Is zlib under the GNU license?
-
- No. Please read the license in zlib.h.
-
-24. The license says that altered source versions must be "plainly marked". So
- what exactly do I need to do to meet that requirement?
-
- You need to change the ZLIB_VERSION and ZLIB_VERNUM #defines in zlib.h. In
- particular, the final version number needs to be changed to "f", and an
- identification string should be appended to ZLIB_VERSION. Version numbers
- x.x.x.f are reserved for modifications to zlib by others than the zlib
- maintainers. For example, if the version of the base zlib you are altering
- is "1.2.3.4", then in zlib.h you should change ZLIB_VERNUM to 0x123f, and
- ZLIB_VERSION to something like "1.2.3.f-zachary-mods-v3". You can also
- update the version strings in deflate.c and inftrees.c.
-
- For altered source distributions, you should also note the origin and
- nature of the changes in zlib.h, as well as in ChangeLog and README, along
- with the dates of the alterations. The origin should include at least your
- name (or your company's name), and an email address to contact for help or
- issues with the library.
-
- Note that distributing a compiled zlib library along with zlib.h and
- zconf.h is also a source distribution, and so you should change
- ZLIB_VERSION and ZLIB_VERNUM and note the origin and nature of the changes
- in zlib.h as you would for a full source distribution.
-
-25. Will zlib work on a big-endian or little-endian architecture, and can I
- exchange compressed data between them?
-
- Yes and yes.
-
-26. Will zlib work on a 64-bit machine?
-
- Yes. It has been tested on 64-bit machines, and has no dependence on any
- data types being limited to 32-bits in length. If you have any
- difficulties, please provide a complete problem report to zlib@gzip.org
-
-27. Will zlib decompress data from the PKWare Data Compression Library?
-
- No. The PKWare DCL uses a completely different compressed data format than
- does PKZIP and zlib. However, you can look in zlib's contrib/blast
- directory for a possible solution to your problem.
-
-28. Can I access data randomly in a compressed stream?
-
- No, not without some preparation. If when compressing you periodically use
- Z_FULL_FLUSH, carefully write all the pending data at those points, and
- keep an index of those locations, then you can start decompression at those
- points. You have to be careful to not use Z_FULL_FLUSH too often, since it
- can significantly degrade compression. Alternatively, you can scan a
- deflate stream once to generate an index, and then use that index for
- random access. See examples/zran.c .
-
-29. Does zlib work on MVS, OS/390, CICS, etc.?
-
- It has in the past, but we have not heard of any recent evidence. There
- were working ports of zlib 1.1.4 to MVS, but those links no longer work.
- If you know of recent, successful applications of zlib on these operating
- systems, please let us know. Thanks.
-
-30. Is there some simpler, easier to read version of inflate I can look at to
- understand the deflate format?
-
- First off, you should read RFC 1951. Second, yes. Look in zlib's
- contrib/puff directory.
-
-31. Does zlib infringe on any patents?
-
- As far as we know, no. In fact, that was originally the whole point behind
- zlib. Look here for some more information:
-
- http://www.gzip.org/#faq11
-
-32. Can zlib work with greater than 4 GB of data?
-
- Yes. inflate() and deflate() will process any amount of data correctly.
- Each call of inflate() or deflate() is limited to input and output chunks
- of the maximum value that can be stored in the compiler's "unsigned int"
- type, but there is no limit to the number of chunks. Note however that the
- strm.total_in and strm_total_out counters may be limited to 4 GB. These
- counters are provided as a convenience and are not used internally by
- inflate() or deflate(). The application can easily set up its own counters
- updated after each call of inflate() or deflate() to count beyond 4 GB.
- compress() and uncompress() may be limited to 4 GB, since they operate in a
- single call. gzseek() and gztell() may be limited to 4 GB depending on how
- zlib is compiled. See the zlibCompileFlags() function in zlib.h.
-
- The word "may" appears several times above since there is a 4 GB limit only
- if the compiler's "long" type is 32 bits. If the compiler's "long" type is
- 64 bits, then the limit is 16 exabytes.
-
-33. Does zlib have any security vulnerabilities?
-
- The only one that we are aware of is potentially in gzprintf(). If zlib is
- compiled to use sprintf() or vsprintf(), then there is no protection
- against a buffer overflow of an 8K string space (or other value as set by
- gzbuffer()), other than the caller of gzprintf() assuring that the output
- will not exceed 8K. On the other hand, if zlib is compiled to use
- snprintf() or vsnprintf(), which should normally be the case, then there is
- no vulnerability. The ./configure script will display warnings if an
- insecure variation of sprintf() will be used by gzprintf(). Also the
- zlibCompileFlags() function will return information on what variant of
- sprintf() is used by gzprintf().
-
- If you don't have snprintf() or vsnprintf() and would like one, you can
- find a portable implementation here:
-
- http://www.ijs.si/software/snprintf/
-
- Note that you should be using the most recent version of zlib. Versions
- 1.1.3 and before were subject to a double-free vulnerability, and versions
- 1.2.1 and 1.2.2 were subject to an access exception when decompressing
- invalid compressed data.
-
-34. Is there a Java version of zlib?
-
- Probably what you want is to use zlib in Java. zlib is already included
- as part of the Java SDK in the java.util.zip package. If you really want
- a version of zlib written in the Java language, look on the zlib home
- page for links: http://zlib.net/ .
-
-35. I get this or that compiler or source-code scanner warning when I crank it
- up to maximally-pedantic. Can't you guys write proper code?
-
- Many years ago, we gave up attempting to avoid warnings on every compiler
- in the universe. It just got to be a waste of time, and some compilers
- were downright silly as well as contradicted each other. So now, we simply
- make sure that the code always works.
-
-36. Valgrind (or some similar memory access checker) says that deflate is
- performing a conditional jump that depends on an uninitialized value.
- Isn't that a bug?
-
- No. That is intentional for performance reasons, and the output of deflate
- is not affected. This only started showing up recently since zlib 1.2.x
- uses malloc() by default for allocations, whereas earlier versions used
- calloc(), which zeros out the allocated memory. Even though the code was
- correct, versions 1.2.4 and later was changed to not stimulate these
- checkers.
-
-37. Will zlib read the (insert any ancient or arcane format here) compressed
- data format?
-
- Probably not. Look in the comp.compression FAQ for pointers to various
- formats and associated software.
-
-38. How can I encrypt/decrypt zip files with zlib?
-
- zlib doesn't support encryption. The original PKZIP encryption is very
- weak and can be broken with freely available programs. To get strong
- encryption, use GnuPG, http://www.gnupg.org/ , which already includes zlib
- compression. For PKZIP compatible "encryption", look at
- http://www.info-zip.org/
-
-39. What's the difference between the "gzip" and "deflate" HTTP 1.1 encodings?
-
- "gzip" is the gzip format, and "deflate" is the zlib format. They should
- probably have called the second one "zlib" instead to avoid confusion with
- the raw deflate compressed data format. While the HTTP 1.1 RFC 2616
- correctly points to the zlib specification in RFC 1950 for the "deflate"
- transfer encoding, there have been reports of servers and browsers that
- incorrectly produce or expect raw deflate data per the deflate
- specification in RFC 1951, most notably Microsoft. So even though the
- "deflate" transfer encoding using the zlib format would be the more
- efficient approach (and in fact exactly what the zlib format was designed
- for), using the "gzip" transfer encoding is probably more reliable due to
- an unfortunate choice of name on the part of the HTTP 1.1 authors.
-
- Bottom line: use the gzip format for HTTP 1.1 encoding.
-
-40. Does zlib support the new "Deflate64" format introduced by PKWare?
-
- No. PKWare has apparently decided to keep that format proprietary, since
- they have not documented it as they have previous compression formats. In
- any case, the compression improvements are so modest compared to other more
- modern approaches, that it's not worth the effort to implement.
-
-41. I'm having a problem with the zip functions in zlib, can you help?
-
- There are no zip functions in zlib. You are probably using minizip by
- Giles Vollant, which is found in the contrib directory of zlib. It is not
- part of zlib. In fact none of the stuff in contrib is part of zlib. The
- files in there are not supported by the zlib authors. You need to contact
- the authors of the respective contribution for help.
-
-42. The match.asm code in contrib is under the GNU General Public License.
- Since it's part of zlib, doesn't that mean that all of zlib falls under the
- GNU GPL?
-
- No. The files in contrib are not part of zlib. They were contributed by
- other authors and are provided as a convenience to the user within the zlib
- distribution. Each item in contrib has its own license.
-
-43. Is zlib subject to export controls? What is its ECCN?
-
- zlib is not subject to export controls, and so is classified as EAR99.
-
-44. Can you please sign these lengthy legal documents and fax them back to us
- so that we can use your software in our product?
-
- No. Go away. Shoo.

-ZLIB DATA COMPRESSION LIBRARY
-
-zlib 1.2.7 is a general purpose data compression library. All the code is
-thread safe. The data format used by the zlib library is described by RFCs
-(Request for Comments) 1950 to 1952 in the files
-http://tools.ietf.org/html/rfc1950 (zlib format), rfc1951 (deflate format) and
-rfc1952 (gzip format).
-
-All functions of the compression library are documented in the file zlib.h
-(volunteer to write man pages welcome, contact zlib@gzip.org). A usage example
-of the library is given in the file test/example.c which also tests that
-the library is working correctly. Another example is given in the file
-test/minigzip.c. The compression library itself is composed of all source
-files in the root directory.
-
-To compile all files and run the test program, follow the instructions given at
-the top of Makefile.in. In short "./configure; make test", and if that goes
-well, "make install" should work for most flavors of Unix. For Windows, use
-one of the special makefiles in win32/ or contrib/vstudio/ . For VMS, use
-make_vms.com.
-
-Questions about zlib should be sent to <zlib@gzip.org>, or to Gilles Vollant
-<info@winimage.com> for the Windows DLL version. The zlib home page is
-http://zlib.net/ . Before reporting a problem, please check this site to
-verify that you have the latest version of zlib; otherwise get the latest
-version and check whether the problem still exists or not.
-
-PLEASE read the zlib FAQ http://zlib.net/zlib_faq.html before asking for help.
-
-Mark Nelson <markn@ieee.org> wrote an article about zlib for the Jan. 1997
-issue of Dr. Dobb's Journal; a copy of the article is available at
-http://marknelson.us/1997/01/01/zlib-engine/ .
-
-The changes made in version 1.2.7 are documented in the file ChangeLog.
-
-Unsupported third party contributions are provided in directory contrib/ .
-
-zlib is available in Java using the java.util.zip package, documented at
-http://java.sun.com/developer/technicalArticles/Programming/compression/ .
-
-A Perl interface to zlib written by Paul Marquess <pmqs@cpan.org> is available
-at CPAN (Comprehensive Perl Archive Network) sites, including
-http://search.cpan.org/~pmqs/IO-Compress-Zlib/ .
-
-A Python interface to zlib written by A.M. Kuchling <amk@amk.ca> is
-available in Python 1.5 and later versions, see
-http://docs.python.org/library/zlib.html .
-
-zlib is built into tcl: http://wiki.tcl.tk/4610 .
-
-An experimental package to read and write files in .zip format, written on top
-of zlib by Gilles Vollant <info@winimage.com>, is available in the
-contrib/minizip directory of zlib.

-
-Notes for some targets:
-
-- For Windows DLL versions, please see win32/DLL_FAQ.txt
-
-- For 64-bit Irix, deflate.c must be compiled without any optimization. With
- -O, one libpng test fails. The test works in 32 bit mode (with the -n32
- compiler flag). The compiler bug has been reported to SGI.
-
-- zlib doesn't work with gcc 2.6.3 on a DEC 3000/300LX under OSF/1 2.1 it works
- when compiled with cc.
-
-- On Digital Unix 4.0D (formely OSF/1) on AlphaServer, the cc option -std1 is
- necessary to get gzprintf working correctly. This is done by configure.
-
-- zlib doesn't work on HP-UX 9.05 with some versions of /bin/cc. It works with
- other compilers. Use "make test" to check your compiler.
-
-- gzdopen is not supported on RISCOS or BEOS.
-
-- For PalmOs, see http://palmzlib.sourceforge.net/

-MiniZip - Copyright (c) 1998-2010 - by Gilles Vollant - version 1.1 64 bits from Mathias Svensson
-
-Introduction
----------------------
-MiniZip 1.1 is built from MiniZip 1.0 by Gilles Vollant ( http://www.winimage.com/zLibDll/minizip.html )
-
-When adding ZIP64 support into minizip it would result into risk of breaking compatibility with minizip 1.0.
-All possible work was done for compatibility.
-
-
-Background
----------------------
-When adding ZIP64 support Mathias Svensson found that Even Rouault have added ZIP64
-support for unzip.c into minizip for a open source project called gdal ( http://www.gdal.org/ )
-
-That was used as a starting point. And after that ZIP64 support was added to zip.c
-some refactoring and code cleanup was also done.
-
-
-Changed from MiniZip 1.0 to MiniZip 1.1
----------------------------------------
-* Added ZIP64 support for unzip ( by Even Rouault )
-* Added ZIP64 support for zip ( by Mathias Svensson )
-* Reverted some changed that Even Rouault did.
-* Bunch of patches received from Gulles Vollant that he received for MiniZip from various users.
-* Added unzip patch for BZIP Compression method (patch create by Daniel Borca)
-* Added BZIP Compress method for zip
-* Did some refactoring and code cleanup
-
-
-Credits
-
- Gilles Vollant - Original MiniZip author
- Even Rouault - ZIP64 unzip Support
- Daniel Borca - BZip Compression method support in unzip
- Mathias Svensson - ZIP64 zip support

- Resources
-
- ZipLayout http://result42.com/projects/ZipFileLayout
- Command line tool for Windows that shows the layout and information of the headers in a zip archive.
- Used when debugging and validating the creation of zip files using MiniZip64

-
-Notes.
- * To be able to use BZip compression method in zip64.c or unzip64.c the BZIP2 lib is needed and HAVE_BZIP2 need to be defined.

- Changes
-
- Oct-2009 - Defined ZPOS64_T to fpos_t on windows and u_int64_t on linux. (might need to find a better why for this)
- Oct-2009 - Change to fseeko64, ftello64 and fopen64 so large files would work on linux.
- More if/def section may be needed to support other platforms
- Oct-2009 - Defined fxxxx64 calls to normal fopen/ftell/fseek so they would compile on windows.
- (but you should use iowin32.c for windows instead)

- ------------------------------------------------------------------------------------
- Decryption code comes from crypt.c by Info-ZIP but has been greatly reduced in terms of
- compatibility with older software. The following is from the original crypt.c.
- Code woven in by Terry Thorsen 1/2003.
-
- Copyright (c) 1990-2000 Info-ZIP. All rights reserved.
-
- See the accompanying file LICENSE, version 2000-Apr-09 or later
- (the contents of which are also included in zip.h) for terms of use.
- If, for some reason, all these files are missing, the Info-ZIP license
- also may be found at: ftp://ftp.info-zip.org/pub/infozip/license.html
-
- crypt.c (full version) by Info-ZIP. Last revised: [see crypt.h]
-
- The encryption/decryption parts of this source code (as opposed to the
- non-echoing password parts) were originally written in Europe. The
- whole source package can be freely distributed, including from the USA.
- (Prior to January 2000, re-export from the US was a violation of US law.)
-
- This encryption code is a direct transcription of the algorithm from
- Roger Schlafly, described by Phil Katz in the file appnote.txt. This
- file (appnote.txt) is distributed with the PKZIP program (even in the
- version without encryption capabilities).
-
- ------------------------------------------------------------------------------------
-
- Changes in unzip.c
-
- 2007-2008 - Even Rouault - Addition of cpl_unzGetCurrentFileZStreamPos
- 2007-2008 - Even Rouault - Decoration of symbol names unz* -> cpl_unz*
- 2007-2008 - Even Rouault - Remove old C style function prototypes
- 2007-2008 - Even Rouault - Add unzip support for ZIP64
-
- Copyright (C) 2007-2008 Even Rouault
-
-
- Oct-2009 - Mathias Svensson - Removed cpl_* from symbol names (Even Rouault added them but since this is now moved to a new project (minizip64) I renamed them again).
- Oct-2009 - Mathias Svensson - Fixed problem if uncompressed size was > 4G and compressed size was <4G
- should only read the compressed/uncompressed size from the Zip64 format if
- the size from normal header was 0xFFFFFFFF
- Oct-2009 - Mathias Svensson - Applied some bug fixes from paches recived from Gilles Vollant
- Oct-2009 - Mathias Svensson - Applied support to unzip files with compression mathod BZIP2 (bzip2 lib is required)
- Patch created by Daniel Borca
-
- Jan-2010 - back to unzip and minizip 1.0 name scheme, with compatibility layer

- Modifications for Zip64 support
- Copyright (C) 2009-2010 Mathias Svensson ( http://result42.com )
-
- For more info read MiniZip_info.txt
-
- Changes
- Oct-2009 - Mathias Svensson - Remove old C style function prototypes
- Oct-2009 - Mathias Svensson - Added Zip64 Support when creating new file archives
- Oct-2009 - Mathias Svensson - Did some code cleanup and refactoring to get better overview of some functions.
- Oct-2009 - Mathias Svensson - Added zipRemoveExtraInfoBlock to strip extra field data from its ZIP64 data
- It is used when recreting zip archive with RAW when deleting items from a zip.
- ZIP64 data is automaticly added to items that needs it, and existing ZIP64 data need to be removed.
- Oct-2009 - Mathias Svensson - Added support for BZIP2 as compression mode (bzip2 lib is required)
- Jan-2010 - back to unzip and minizip 1.0 name scheme, with compatibility layer

-Building instructions for the DLL versions of Zlib 1.2.7
-========================================================
-
-This directory contains projects that build zlib and minizip using
-Microsoft Visual C++ 9.0/10.0.
-
-You don't need to build these projects yourself. You can download the
-binaries from:
- http://www.winimage.com/zLibDll
-
-More information can be found at this site.
-
-
-
-
-
-Build instructions for Visual Studio 2008 (32 bits or 64 bits)
---------------------------------------------------------------
-- Uncompress current zlib, including all contrib/* files
-- Compile assembly code (with Visual Studio Command Prompt) by running:
- bld_ml64.bat (in contrib\masmx64)
- bld_ml32.bat (in contrib\masmx86)
-- Open contrib\vstudio\vc9\zlibvc.sln with Microsoft Visual C++ 2008
-- Or run: vcbuild /rebuild contrib\vstudio\vc9\zlibvc.sln "Release|Win32"
-
-Build instructions for Visual Studio 2010 (32 bits or 64 bits)
---------------------------------------------------------------
-- Uncompress current zlib, including all contrib/* files
-- Open contrib\vstudio\vc10\zlibvc.sln with Microsoft Visual C++ 2010
-
-
-Important
----------
-- To use zlibwapi.dll in your application, you must define the
- macro ZLIB_WINAPI when compiling your application's source files.
-
-
-Additional notes
-----------------
-- This DLL, named zlibwapi.dll, is compatible to the old zlib.dll built
- by Gilles Vollant from the zlib 1.1.x sources, and distributed at
- http://www.winimage.com/zLibDll
- It uses the WINAPI calling convention for the exported functions, and
- includes the minizip functionality. If your application needs that
- particular build of zlib.dll, you can rename zlibwapi.dll to zlib.dll.
-
-- The new DLL was renamed because there exist several incompatible
- versions of zlib.dll on the Internet.
-
-- There is also an official DLL build of zlib, named zlib1.dll. This one
- is exporting the functions using the CDECL convention. See the file
- win32\DLL_FAQ.txt found in this zlib distribution.
-
-- There used to be a ZLIB_DLL macro in zlib 1.1.x, but now this symbol
- has a slightly different effect. To avoid compatibility problems, do
- not define it here.

-Abstract
-
- This specification defines a lossless compressed data format. The
- data can be produced or consumed, even for an arbitrarily long
- sequentially presented input data stream, using only an a priori
- bounded amount of intermediate storage. The format presently uses
- the DEFLATE compression method but can be easily extended to use
- other compression methods. It can be implemented readily in a manner
- not covered by patents. This specification also defines the ADLER-32
- checksum (an extension and improvement of the Fletcher checksum),
- used for detection of data corruption, and provides an algorithm for
- computing it.

-1. Introduction
-
- 1.1. Purpose
-
- The purpose of this specification is to define a lossless
- compressed data format that:
-
- * Is independent of CPU type, operating system, file system,
- and character set, and hence can be used for interchange;
-
- * Can be produced or consumed, even for an arbitrarily long
- sequentially presented input data stream, using only an a
- priori bounded amount of intermediate storage, and hence can
- be used in data communications or similar structures such as
- Unix filters;
-
- * Can use a number of different compression methods;
-
- * Can be implemented readily in a manner not covered by
- patents, and hence can be practiced freely.
-
- The data format defined by this specification does not attempt to
- allow random access to compressed data.

-RFC 1950 ZLIB Compressed Data Format Specification May 1996
-
-
- 1.2. Intended audience
-
- This specification is intended for use by implementors of software
- to compress data into zlib format and/or decompress data from zlib
- format.
-
- The text of the specification assumes a basic background in
- programming at the level of bits and other primitive data
- representations.
-
- 1.3. Scope
-
- The specification specifies a compressed data format that can be
- used for in-memory compression of a sequence of arbitrary bytes.
-
- 1.4. Compliance
-
- Unless otherwise indicated below, a compliant decompressor must be
- able to accept and decompress any data set that conforms to all
- the specifications presented here; a compliant compressor must
- produce data sets that conform to all the specifications presented
- here.
-
- 1.5. Definitions of terms and conventions used
-
- byte: 8 bits stored or transmitted as a unit (same as an octet).
- (For this specification, a byte is exactly 8 bits, even on
- machines which store a character on a number of bits different
- from 8.) See below, for the numbering of bits within a byte.
-
- 1.6. Changes from previous versions
-
- Version 3.1 was the first public release of this specification.
- In version 3.2, some terminology was changed and the Adler-32
- sample code was rewritten for clarity. In version 3.3, the
- support for a preset dictionary was introduced, and the
- specification was converted to RFC style.
-
-2. Detailed specification
-
- 2.1. Overall conventions
-
- In the diagrams below, a box like this:
-
- +---+
- | | <-- the vertical bars might be missing
- +---+
-
-
-
-
-Deutsch & Gailly Informational [Page 3]
-
-RFC 1950 ZLIB Compressed Data Format Specification May 1996
-
-
- represents one byte; a box like this:
-
- +==============+
- | |
- +==============+
-
- represents a variable number of bytes.
-
- Bytes stored within a computer do not have a "bit order", since
- they are always treated as a unit. However, a byte considered as
- an integer between 0 and 255 does have a most- and least-
- significant bit, and since we write numbers with the most-
- significant digit on the left, we also write bytes with the most-
- significant bit on the left. In the diagrams below, we number the
- bits of a byte so that bit 0 is the least-significant bit, i.e.,
- the bits are numbered:
-
- +--------+
- |76543210|
- +--------+
-
- Within a computer, a number may occupy multiple bytes. All
- multi-byte numbers in the format described here are stored with
- the MOST-significant byte first (at the lower memory address).
- For example, the decimal number 520 is stored as:
-
- 0 1
- +--------+--------+
- |00000010|00001000|
- +--------+--------+
- ^ ^
- | |
- | + less significant byte = 8
- + more significant byte = 2 x 256
-
- 2.2. Data format
-
- A zlib stream has the following structure:
-
- 0 1
- +---+---+
- |CMF|FLG| (more-->)
- +---+---+
-
-
-
-
-
-
-
-
-Deutsch & Gailly Informational [Page 4]
-
-RFC 1950 ZLIB Compressed Data Format Specification May 1996
-
-
- (if FLG.FDICT set)
-
- 0 1 2 3
- +---+---+---+---+
- | DICTID | (more-->)
- +---+---+---+---+
-
- +=====================+---+---+---+---+
- |...compressed data...| ADLER32 |
- +=====================+---+---+---+---+
-
- Any data which may appear after ADLER32 are not part of the zlib
- stream.
-
- CMF (Compression Method and flags)
- This byte is divided into a 4-bit compression method and a 4-
- bit information field depending on the compression method.
-
- bits 0 to 3 CM Compression method
- bits 4 to 7 CINFO Compression info
-
- CM (Compression method)
- This identifies the compression method used in the file. CM = 8
- denotes the "deflate" compression method with a window size up
- to 32K. This is the method used by gzip and PNG (see
- references [1] and [2] in Chapter 3, below, for the reference
- documents). CM = 15 is reserved. It might be used in a future
- version of this specification to indicate the presence of an
- extra field before the compressed data.
-
- CINFO (Compression info)
- For CM = 8, CINFO is the base-2 logarithm of the LZ77 window
- size, minus eight (CINFO=7 indicates a 32K window size). Values
- of CINFO above 7 are not allowed in this version of the
- specification. CINFO is not defined in this specification for
- CM not equal to 8.
-
- FLG (FLaGs)
- This flag byte is divided as follows:
-
- bits 0 to 4 FCHECK (check bits for CMF and FLG)
- bit 5 FDICT (preset dictionary)
- bits 6 to 7 FLEVEL (compression level)
-
- The FCHECK value must be such that CMF and FLG, when viewed as
- a 16-bit unsigned integer stored in MSB order (CMF*256 + FLG),
- is a multiple of 31.
-
-
-
-
-Deutsch & Gailly Informational [Page 5]
-
-RFC 1950 ZLIB Compressed Data Format Specification May 1996
-
-
- FDICT (Preset dictionary)
- If FDICT is set, a DICT dictionary identifier is present
- immediately after the FLG byte. The dictionary is a sequence of
- bytes which are initially fed to the compressor without
- producing any compressed output. DICT is the Adler-32 checksum
- of this sequence of bytes (see the definition of ADLER32
- below). The decompressor can use this identifier to determine
- which dictionary has been used by the compressor.
-
- FLEVEL (Compression level)
- These flags are available for use by specific compression
- methods. The "deflate" method (CM = 8) sets these flags as
- follows:
-
- 0 - compressor used fastest algorithm
- 1 - compressor used fast algorithm
- 2 - compressor used default algorithm
- 3 - compressor used maximum compression, slowest algorithm
-
- The information in FLEVEL is not needed for decompression; it
- is there to indicate if recompression might be worthwhile.
-
- compressed data
- For compression method 8, the compressed data is stored in the
- deflate compressed data format as described in the document
- "DEFLATE Compressed Data Format Specification" by L. Peter
- Deutsch. (See reference [3] in Chapter 3, below)
-
- Other compressed data formats are not specified in this version
- of the zlib specification.
-
- ADLER32 (Adler-32 checksum)
- This contains a checksum value of the uncompressed data
- (excluding any dictionary data) computed according to Adler-32
- algorithm. This algorithm is a 32-bit extension and improvement
- of the Fletcher algorithm, used in the ITU-T X.224 / ISO 8073
- standard. See references [4] and [5] in Chapter 3, below)
-
- Adler-32 is composed of two sums accumulated per byte: s1 is
- the sum of all bytes, s2 is the sum of all s1 values. Both sums
- are done modulo 65521. s1 is initialized to 1, s2 to zero. The
- Adler-32 checksum is stored as s2*65536 + s1 in most-
- significant-byte first (network) order.

-
-
- 2.3. Compliance
-
- A compliant compressor must produce streams with correct CMF, FLG
- and ADLER32, but need not support preset dictionaries. When the
- zlib data format is used as part of another standard data format,
- the compressor may use only preset dictionaries that are specified
- by this other data format. If this other format does not use the
- preset dictionary feature, the compressor must not set the FDICT
- flag.
-
- A compliant decompressor must check CMF, FLG, and ADLER32, and
- provide an error indication if any of these have incorrect values.
- A compliant decompressor must give an error indication if CM is
- not one of the values defined in this specification (only the
- value 8 is permitted in this version), since another value could
- indicate the presence of new features that would cause subsequent
- data to be interpreted incorrectly. A compliant decompressor must
- give an error indication if FDICT is set and DICTID is not the
- identifier of a known preset dictionary. A decompressor may
- ignore FLEVEL and still be compliant. When the zlib data format
- is being used as a part of another standard format, a compliant
- decompressor must support all the preset dictionaries specified by
- the other format. When the other format does not use the preset
- dictionary feature, a compliant decompressor must reject any
- stream in which the FDICT flag is set.

-8. Appendix: Rationale
-
- 8.1. Preset dictionaries
-
- A preset dictionary is specially useful to compress short input
- sequences. The compressor can take advantage of the dictionary
- context to encode the input in a more compact manner. The
- decompressor can be initialized with the appropriate context by
- virtually decompressing a compressed version of the dictionary
- without producing any output. However for certain compression
- algorithms such as the deflate algorithm this operation can be
- achieved without actually performing any decompression.
-
- The compressor and the decompressor must use exactly the same
- dictionary. The dictionary may be fixed or may be chosen among a
- certain number of predefined dictionaries, according to the kind
- of input data. The decompressor can determine which dictionary has
- been chosen by the compressor by checking the dictionary
- identifier. This document does not specify the contents of
- predefined dictionaries, since the optimal dictionaries are
- application specific. Standard data formats using this feature of
- the zlib specification must precisely define the allowed
- dictionaries.
-
- 8.2. The Adler-32 algorithm
-
- The Adler-32 algorithm is much faster than the CRC32 algorithm yet
- still provides an extremely low probability of undetected errors.
-
- The modulo on unsigned long accumulators can be delayed for 5552
- bytes, so the modulo operation time is negligible. If the bytes
- are a, b, c, the second sum is 3a + 2b + c + 3, and so is position
- and order sensitive, unlike the first sum, which is just a
- checksum. That 65521 is prime is important to avoid a possible
- large class of two-byte errors that leave the check unchanged.
- (The Fletcher checksum uses 255, which is not prime and which also
- makes the Fletcher check insensitive to single byte changes 0 <->
- 255.)
-
- The sum s1 is initialized to 1 instead of zero to make the length
- of the sequence part of s2, so that the length does not have to be
- checked separately. (Any sequence of zeroes has a Fletcher
- checksum of zero.)

-
-9. Appendix: Sample code
-
- The following C code computes the Adler-32 checksum of a data buffer.
- It is written for clarity, not for speed. The sample code is in the
- ANSI C programming language. Non C users may find it easier to read
- with these hints:
-
- & Bitwise AND operator.
- >> Bitwise right shift operator. When applied to an
- unsigned quantity, as here, right shift inserts zero bit(s)
- at the left.
- << Bitwise left shift operator. Left shift inserts zero
- bit(s) at the right.
- ++ "n++" increments the variable n.
- % modulo operator: a % b is the remainder of a divided by b.
-
- #define BASE 65521 /* largest prime smaller than 65536 */
-
- /*
- Update a running Adler-32 checksum with the bytes buf[0..len-1]
- and return the updated checksum. The Adler-32 checksum should be
- initialized to 1.
-
- Usage example:
-
- unsigned long adler = 1L;
-
- while (read_buffer(buffer, length) != EOF) {
- adler = update_adler32(adler, buffer, length);
- }
- if (adler != original_adler) error();
- */
- unsigned long update_adler32(unsigned long adler,
- unsigned char *buf, int len)
- {
- unsigned long s1 = adler & 0xffff;
- unsigned long s2 = (adler >> 16) & 0xffff;
- int n;
-
- for (n = 0; n < len; n++) {
- s1 = (s1 + buf[n]) % BASE;
- s2 = (s2 + s1) % BASE;
- }
- return (s2 << 16) + s1;
- }
-
- /* Return the adler32 of the bytes buf[0..len-1] */

-Abstract
-
- This specification defines a lossless compressed data format that
- compresses data using a combination of the LZ77 algorithm and Huffman
- coding, with efficiency comparable to the best currently available
- general-purpose compression methods. The data can be produced or
- consumed, even for an arbitrarily long sequentially presented input
- data stream, using only an a priori bounded amount of intermediate
- storage. The format can be implemented readily in a manner not
- covered by patents.

-1. Introduction
-
- 1.1. Purpose
-
- The purpose of this specification is to define a lossless
- compressed data format that:
- * Is independent of CPU type, operating system, file system,
- and character set, and hence can be used for interchange;
- * Can be produced or consumed, even for an arbitrarily long
- sequentially presented input data stream, using only an a
- priori bounded amount of intermediate storage, and hence
- can be used in data communications or similar structures
- such as Unix filters;
- * Compresses data with efficiency comparable to the best
- currently available general-purpose compression methods,
- and in particular considerably better than the "compress"
- program;
- * Can be implemented readily in a manner not covered by
- patents, and hence can be practiced freely;
-
-
-
-Deutsch Informational [Page 2]
-
-RFC 1951 DEFLATE Compressed Data Format Specification May 1996
-
-
- * Is compatible with the file format produced by the current
- widely used gzip utility, in that conforming decompressors
- will be able to read data produced by the existing gzip
- compressor.
-
- The data format defined by this specification does not attempt to:
-
- * Allow random access to compressed data;
- * Compress specialized data (e.g., raster graphics) as well
- as the best currently available specialized algorithms.
-
- A simple counting argument shows that no lossless compression
- algorithm can compress every possible input data set. For the
- format defined here, the worst case expansion is 5 bytes per 32K-
- byte block, i.e., a size increase of 0.015% for large data sets.
- English text usually compresses by a factor of 2.5 to 3;
- executable files usually compress somewhat less; graphical data
- such as raster images may compress much more.
-
- 1.2. Intended audience
-
- This specification is intended for use by implementors of software
- to compress data into "deflate" format and/or decompress data from
- "deflate" format.
-
- The text of the specification assumes a basic background in
- programming at the level of bits and other primitive data
- representations. Familiarity with the technique of Huffman coding
- is helpful but not required.
-
- 1.3. Scope
-
- The specification specifies a method for representing a sequence
- of bytes as a (usually shorter) sequence of bits, and a method for
- packing the latter bit sequence into bytes.
-
- 1.4. Compliance
-
- Unless otherwise indicated below, a compliant decompressor must be
- able to accept and decompress any data set that conforms to all
- the specifications presented here; a compliant compressor must
- produce data sets that conform to all the specifications presented
- here.
-
- 1.5. Definitions of terms and conventions used
-
- Byte: 8 bits stored or transmitted as a unit (same as an octet).
- For this specification, a byte is exactly 8 bits, even on machines
-
-
-
-Deutsch Informational [Page 3]
-
-RFC 1951 DEFLATE Compressed Data Format Specification May 1996
-
-
- which store a character on a number of bits different from eight.
- See below, for the numbering of bits within a byte.
-
- String: a sequence of arbitrary bytes.
-
- 1.6. Changes from previous versions
-
- There have been no technical changes to the deflate format since
- version 1.1 of this specification. In version 1.2, some
- terminology was changed. Version 1.3 is a conversion of the
- specification to RFC style.
-
-2. Compressed representation overview
-
- A compressed data set consists of a series of blocks, corresponding
- to successive blocks of input data. The block sizes are arbitrary,
- except that non-compressible blocks are limited to 65,535 bytes.
-
- Each block is compressed using a combination of the LZ77 algorithm
- and Huffman coding. The Huffman trees for each block are independent
- of those for previous or subsequent blocks; the LZ77 algorithm may
- use a reference to a duplicated string occurring in a previous block,
- up to 32K input bytes before.
-
- Each block consists of two parts: a pair of Huffman code trees that
- describe the representation of the compressed data part, and a
- compressed data part. (The Huffman trees themselves are compressed
- using Huffman encoding.) The compressed data consists of a series of
- elements of two types: literal bytes (of strings that have not been
- detected as duplicated within the previous 32K input bytes), and
- pointers to duplicated strings, where a pointer is represented as a
- pair <length, backward distance>. The representation used in the
- "deflate" format limits distances to 32K bytes and lengths to 258
- bytes, but does not limit the size of a block, except for
- uncompressible blocks, which are limited as noted above.
-
- Each type of value (literals, distances, and lengths) in the
- compressed data is represented using a Huffman code, using one code
- tree for literals and lengths and a separate code tree for distances.
- The code trees for each block appear in a compact form just before
- the compressed data for that block.

-3. Detailed specification
-
- 3.1. Overall conventions In the diagrams below, a box like this:
-
- +---+
- | | <-- the vertical bars might be missing
- +---+
-
- represents one byte; a box like this:
-
- +==============+
- | |
- +==============+
-
- represents a variable number of bytes.
-
- Bytes stored within a computer do not have a "bit order", since
- they are always treated as a unit. However, a byte considered as
- an integer between 0 and 255 does have a most- and least-
- significant bit, and since we write numbers with the most-
- significant digit on the left, we also write bytes with the most-
- significant bit on the left. In the diagrams below, we number the
- bits of a byte so that bit 0 is the least-significant bit, i.e.,
- the bits are numbered:
-
- +--------+
- |76543210|
- +--------+
-
- Within a computer, a number may occupy multiple bytes. All
- multi-byte numbers in the format described here are stored with
- the least-significant byte first (at the lower memory address).
- For example, the decimal number 520 is stored as:
-
- 0 1
- +--------+--------+
- |00001000|00000010|
- +--------+--------+
- ^ ^
- | |
- | + more significant byte = 2 x 256
- + less significant byte = 8
-
- 3.1.1. Packing into bytes
-
- This document does not address the issue of the order in which
- bits of a byte are transmitted on a bit-sequential medium,
- since the final data format described here is byte- rather than
-
-
-
-Deutsch Informational [Page 5]
-
-RFC 1951 DEFLATE Compressed Data Format Specification May 1996
-
-
- bit-oriented. However, we describe the compressed block format
- in below, as a sequence of data elements of various bit
- lengths, not a sequence of bytes. We must therefore specify
- how to pack these data elements into bytes to form the final
- compressed byte sequence:
-
- * Data elements are packed into bytes in order of
- increasing bit number within the byte, i.e., starting
- with the least-significant bit of the byte.
- * Data elements other than Huffman codes are packed
- starting with the least-significant bit of the data
- element.
- * Huffman codes are packed starting with the most-
- significant bit of the code.
-
- In other words, if one were to print out the compressed data as
- a sequence of bytes, starting with the first byte at the
- *right* margin and proceeding to the *left*, with the most-
- significant bit of each byte on the left as usual, one would be
- able to parse the result from right to left, with fixed-width
- elements in the correct MSB-to-LSB order and Huffman codes in
- bit-reversed order (i.e., with the first bit of the code in the
- relative LSB position).
-
- 3.2. Compressed block format
-
- 3.2.1. Synopsis of prefix and Huffman coding
-
- Prefix coding represents symbols from an a priori known
- alphabet by bit sequences (codes), one code for each symbol, in
- a manner such that different symbols may be represented by bit
- sequences of different lengths, but a parser can always parse
- an encoded string unambiguously symbol-by-symbol.
-
- We define a prefix code in terms of a binary tree in which the
- two edges descending from each non-leaf node are labeled 0 and
- 1 and in which the leaf nodes correspond one-for-one with (are
- labeled with) the symbols of the alphabet; then the code for a
- symbol is the sequence of 0's and 1's on the edges leading from
- the root to the leaf labeled with that symbol. For example:
-
-
-
-
-
-
-
-
-
-
-
-Deutsch Informational [Page 6]
-
-RFC 1951 DEFLATE Compressed Data Format Specification May 1996
-
-
- /\ Symbol Code
- 0 1 ------ ----
- / \ A 00
- /\ B B 1
- 0 1 C 011
- / \ D 010
- A /\
- 0 1
- / \
- D C
-
- A parser can decode the next symbol from an encoded input
- stream by walking down the tree from the root, at each step
- choosing the edge corresponding to the next input bit.
-
- Given an alphabet with known symbol frequencies, the Huffman
- algorithm allows the construction of an optimal prefix code
- (one which represents strings with those symbol frequencies
- using the fewest bits of any possible prefix codes for that
- alphabet). Such a code is called a Huffman code. (See
- reference [1] in Chapter 5, references for additional
- information on Huffman codes.)
-
- Note that in the "deflate" format, the Huffman codes for the
- various alphabets must not exceed certain maximum code lengths.
- This constraint complicates the algorithm for computing code
- lengths from symbol frequencies. Again, see Chapter 5,
- references for details.
-
- 3.2.2. Use of Huffman coding in the "deflate" format
-
- The Huffman codes used for each alphabet in the "deflate"
- format have two additional rules:
-
- * All codes of a given bit length have lexicographically
- consecutive values, in the same order as the symbols
- they represent;
-
- * Shorter codes lexicographically precede longer codes.
-
-
-
-
-
-
-
-
-
-
-
-
-Deutsch Informational [Page 7]
-
-RFC 1951 DEFLATE Compressed Data Format Specification May 1996
-
-
- We could recode the example above to follow this rule as
- follows, assuming that the order of the alphabet is ABCD:
-
- Symbol Code
- ------ ----
- A 10
- B 0
- C 110
- D 111
-
- I.e., 0 precedes 10 which precedes 11x, and 110 and 111 are
- lexicographically consecutive.
-
- Given this rule, we can define the Huffman code for an alphabet
- just by giving the bit lengths of the codes for each symbol of
- the alphabet in order; this is sufficient to determine the
- actual codes. In our example, the code is completely defined
- by the sequence of bit lengths (2, 1, 3, 3). The following
- algorithm generates the codes as integers, intended to be read
- from most- to least-significant bit. The code lengths are
- initially in tree[I].Len; the codes are produced in
- tree[I].Code.
-
- 1) Count the number of codes for each code length. Let
- bl_count[N] be the number of codes of length N, N >= 1.
-
- 2) Find the numerical value of the smallest code for each
- code length:
-
- code = 0;
- bl_count[0] = 0;
- for (bits = 1; bits <= MAX_BITS; bits++) {
- code = (code + bl_count[bits-1]) << 1;
- next_code[bits] = code;
- }
-
- 3) Assign numerical values to all codes, using consecutive
- values for all codes of the same length with the base
- values determined at step 2. Codes that are never used
- (which have a bit length of zero) must not be assigned a
- value.
-
- for (n = 0; n <= max_code; n++) {
- len = tree[n].Len;
- if (len != 0) {
- tree[n].Code = next_code[len];
- next_code[len]++;
- }
-

-
- }
-
- Example:
-
- Consider the alphabet ABCDEFGH, with bit lengths (3, 3, 3, 3,
- 3, 2, 4, 4). After step 1, we have:
-
- N bl_count[N]
- - -----------
- 2 1
- 3 5
- 4 2
-
- Step 2 computes the following next_code values:
-
- N next_code[N]
- - ------------
- 1 0
- 2 0
- 3 2
- 4 14
-
- Step 3 produces the following code values:
-
- Symbol Length Code
- ------ ------ ----
- A 3 010
- B 3 011
- C 3 100
- D 3 101
- E 3 110
- F 2 00
- G 4 1110
- H 4 1111
-
- 3.2.3. Details of block format
-
- Each block of compressed data begins with 3 header bits
- containing the following data:
-
- first bit BFINAL
- next 2 bits BTYPE
-
- Note that the header bits do not necessarily begin on a byte
- boundary, since a block does not necessarily occupy an integral
- number of bytes.
-
-
-
-
-
-Deutsch Informational [Page 9]
-
-RFC 1951 DEFLATE Compressed Data Format Specification May 1996
-
-
- BFINAL is set if and only if this is the last block of the data
- set.
-
- BTYPE specifies how the data are compressed, as follows:
-
- 00 - no compression
- 01 - compressed with fixed Huffman codes
- 10 - compressed with dynamic Huffman codes
- 11 - reserved (error)
-
- The only difference between the two compressed cases is how the
- Huffman codes for the literal/length and distance alphabets are
- defined.
-
- In all cases, the decoding algorithm for the actual data is as
- follows:
-
- do
- read block header from input stream.
- if stored with no compression
- skip any remaining bits in current partially
- processed byte
- read LEN and NLEN (see next section)
- copy LEN bytes of data to output
- otherwise
- if compressed with dynamic Huffman codes
- read representation of code trees (see
- subsection below)
- loop (until end of block code recognized)
- decode literal/length value from input stream
- if value < 256
- copy value (literal byte) to output stream
- otherwise
- if value = end of block (256)
- break from loop
- otherwise (value = 257..285)
- decode distance from input stream
-
- move backwards distance bytes in the output
- stream, and copy length bytes from this
- position to the output stream.
- end loop
- while not last block
-
- Note that a duplicated string reference may refer to a string
- in a previous block; i.e., the backward distance may cross one
- or more block boundaries. However a distance cannot refer past
- the beginning of the output stream. (An application using a
-
-
-
-Deutsch Informational [Page 10]
-
-RFC 1951 DEFLATE Compressed Data Format Specification May 1996
-
-
- preset dictionary might discard part of the output stream; a
- distance can refer to that part of the output stream anyway)
- Note also that the referenced string may overlap the current
- position; for example, if the last 2 bytes decoded have values
- X and Y, a string reference with <length = 5, distance = 2>
- adds X,Y,X,Y,X to the output stream.
-
- We now specify each compression method in turn.
-
- 3.2.4. Non-compressed blocks (BTYPE=00)
-
- Any bits of input up to the next byte boundary are ignored.
- The rest of the block consists of the following information:
-
- 0 1 2 3 4...
- +---+---+---+---+================================+
- | LEN | NLEN |... LEN bytes of literal data...|
- +---+---+---+---+================================+
-
- LEN is the number of data bytes in the block. NLEN is the
- one's complement of LEN.
-
- 3.2.5. Compressed blocks (length and distance codes)
-
- As noted above, encoded data blocks in the "deflate" format
- consist of sequences of symbols drawn from three conceptually
- distinct alphabets: either literal bytes, from the alphabet of
- byte values (0..255), or <length, backward distance> pairs,
- where the length is drawn from (3..258) and the distance is
- drawn from (1..32,768). In fact, the literal and length
- alphabets are merged into a single alphabet (0..285), where
- values 0..255 represent literal bytes, the value 256 indicates
- end-of-block, and values 257..285 represent length codes
- (possibly in conjunction with extra bits following the symbol
- code) as follows:

-
- 3.2.6. Compression with fixed Huffman codes (BTYPE=01)
-
- The Huffman codes for the two alphabets are fixed, and are not
- represented explicitly in the data. The Huffman code lengths
- for the literal/length alphabet are:
-
- Lit Value Bits Codes
- --------- ---- -----
- 0 - 143 8 00110000 through
- 10111111
- 144 - 255 9 110010000 through
- 111111111
- 256 - 279 7 0000000 through
- 0010111
- 280 - 287 8 11000000 through
- 11000111
-
-
-
-Deutsch Informational [Page 12]
-
-RFC 1951 DEFLATE Compressed Data Format Specification May 1996
-
-
- The code lengths are sufficient to generate the actual codes,
- as described above; we show the codes in the table for added
- clarity. Literal/length values 286-287 will never actually
- occur in the compressed data, but participate in the code
- construction.
-
- Distance codes 0-31 are represented by (fixed-length) 5-bit
- codes, with possible additional bits as shown in the table
- shown in Paragraph 3.2.5, above. Note that distance codes 30-
- 31 will never actually occur in the compressed data.
-
- 3.2.7. Compression with dynamic Huffman codes (BTYPE=10)
-
- The Huffman codes for the two alphabets appear in the block
- immediately after the header bits and before the actual
- compressed data, first the literal/length code and then the
- distance code. Each code is defined by a sequence of code
- lengths, as discussed in Paragraph 3.2.2, above. For even
- greater compactness, the code length sequences themselves are
- compressed using a Huffman code. The alphabet for code lengths
- is as follows:
-
- 0 - 15: Represent code lengths of 0 - 15
- 16: Copy the previous code length 3 - 6 times.
- The next 2 bits indicate repeat length
- (0 = 3, ... , 3 = 6)
- Example: Codes 8, 16 (+2 bits 11),
- 16 (+2 bits 10) will expand to
- 12 code lengths of 8 (1 + 6 + 5)
- 17: Repeat a code length of 0 for 3 - 10 times.
- (3 bits of length)
- 18: Repeat a code length of 0 for 11 - 138 times
- (7 bits of length)
-
- A code length of 0 indicates that the corresponding symbol in
- the literal/length or distance alphabet will not occur in the
- block, and should not participate in the Huffman code
- construction algorithm given earlier. If only one distance
- code is used, it is encoded using one bit, not zero bits; in
- this case there is a single code length of one, with one unused
- code. One distance code of zero bits means that there are no
- distance codes used at all (the data is all literals).
-
- We can now define the format of the block:
-
- 5 Bits: HLIT, # of Literal/Length codes - 257 (257 - 286)
- 5 Bits: HDIST, # of Distance codes - 1 (1 - 32)
- 4 Bits: HCLEN, # of Code Length codes - 4 (4 - 19)
-
-
-
-Deutsch Informational [Page 13]
-
-RFC 1951 DEFLATE Compressed Data Format Specification May 1996
-
-
- (HCLEN + 4) x 3 bits: code lengths for the code length
- alphabet given just above, in the order: 16, 17, 18,
- 0, 8, 7, 9, 6, 10, 5, 11, 4, 12, 3, 13, 2, 14, 1, 15
-
- These code lengths are interpreted as 3-bit integers
- (0-7); as above, a code length of 0 means the
- corresponding symbol (literal/length or distance code
- length) is not used.
-
- HLIT + 257 code lengths for the literal/length alphabet,
- encoded using the code length Huffman code
-
- HDIST + 1 code lengths for the distance alphabet,
- encoded using the code length Huffman code
-
- The actual compressed data of the block,
- encoded using the literal/length and distance Huffman
- codes
-
- The literal/length symbol 256 (end of data),
- encoded using the literal/length Huffman code
-
- The code length repeat codes can cross from HLIT + 257 to the
- HDIST + 1 code lengths. In other words, all code lengths form
- a single sequence of HLIT + HDIST + 258 values.
-
- 3.3. Compliance
-
- A compressor may limit further the ranges of values specified in
- the previous section and still be compliant; for example, it may
- limit the range of backward pointers to some value smaller than
- 32K. Similarly, a compressor may limit the size of blocks so that
- a compressible block fits in memory.
-
- A compliant decompressor must accept the full range of possible
- values defined in the previous section, and must accept blocks of
- arbitrary size.
-
-4. Compression algorithm details
-
- While it is the intent of this document to define the "deflate"
- compressed data format without reference to any particular
- compression algorithm, the format is related to the compressed
- formats produced by LZ77 (Lempel-Ziv 1977, see reference [2] below);
- since many variations of LZ77 are patented, it is strongly
- recommended that the implementor of a compressor follow the general
- algorithm presented here, which is known not to be patented per se.
- The material in this section is not part of the definition of the
-
-
-
-Deutsch Informational [Page 14]
-
-RFC 1951 DEFLATE Compressed Data Format Specification May 1996
-
-
- specification per se, and a compressor need not follow it in order to
- be compliant.
-
- The compressor terminates a block when it determines that starting a
- new block with fresh trees would be useful, or when the block size
- fills up the compressor's block buffer.
-
- The compressor uses a chained hash table to find duplicated strings,
- using a hash function that operates on 3-byte sequences. At any
- given point during compression, let XYZ be the next 3 input bytes to
- be examined (not necessarily all different, of course). First, the
- compressor examines the hash chain for XYZ. If the chain is empty,
- the compressor simply writes out X as a literal byte and advances one
- byte in the input. If the hash chain is not empty, indicating that
- the sequence XYZ (or, if we are unlucky, some other 3 bytes with the
- same hash function value) has occurred recently, the compressor
- compares all strings on the XYZ hash chain with the actual input data
- sequence starting at the current point, and selects the longest
- match.
-
- The compressor searches the hash chains starting with the most recent
- strings, to favor small distances and thus take advantage of the
- Huffman encoding. The hash chains are singly linked. There are no
- deletions from the hash chains; the algorithm simply discards matches
- that are too old. To avoid a worst-case situation, very long hash
- chains are arbitrarily truncated at a certain length, determined by a
- run-time parameter.
-
- To improve overall compression, the compressor optionally defers the
- selection of matches ("lazy matching"): after a match of length N has
- been found, the compressor searches for a longer match starting at
- the next input byte. If it finds a longer match, it truncates the
- previous match to a length of one (thus producing a single literal
- byte) and then emits the longer match. Otherwise, it emits the
- original match, and, as described above, advances N bytes before
- continuing.
-
- Run-time parameters also control this "lazy match" procedure. If
- compression ratio is most important, the compressor attempts a
- complete second search regardless of the length of the first match.
- In the normal case, if the current match is "long enough", the
- compressor reduces the search for a longer match, thus speeding up
- the process. If speed is most important, the compressor inserts new
- strings in the hash table only when no match was found, or when the
- match is not "too long". This degrades the compression ratio but
- saves time since there are both fewer insertions and fewer searches.

- This specification defines a lossless compressed data format that is
- compatible with the widely used GZIP utility. The format includes a
- cyclic redundancy check value for detecting data corruption. The
- format presently uses the DEFLATE method of compression but can be
- easily extended to use other compression methods. The format can be
- implemented readily in a manner not covered by patents.

-1. Introduction
-
- 1.1. Purpose
-
- The purpose of this specification is to define a lossless
- compressed data format that:
-
- * Is independent of CPU type, operating system, file system,
- and character set, and hence can be used for interchange;
- * Can compress or decompress a data stream (as opposed to a
- randomly accessible file) to produce another data stream,
- using only an a priori bounded amount of intermediate
- storage, and hence can be used in data communications or
- similar structures such as Unix filters;
- * Compresses data with efficiency comparable to the best
- currently available general-purpose compression methods,
- and in particular considerably better than the "compress"
- program;
- * Can be implemented readily in a manner not covered by
- patents, and hence can be practiced freely;
- * Is compatible with the file format produced by the current
- widely used gzip utility, in that conforming decompressors
- will be able to read data produced by the existing gzip
- compressor.
-
-
-
-
-Deutsch Informational [Page 2]
-
-RFC 1952 GZIP File Format Specification May 1996
-
-
- The data format defined by this specification does not attempt to:
-
- * Provide random access to compressed data;
- * Compress specialized data (e.g., raster graphics) as well as
- the best currently available specialized algorithms.
-
- 1.2. Intended audience
-
- This specification is intended for use by implementors of software
- to compress data into gzip format and/or decompress data from gzip
- format.
-
- The text of the specification assumes a basic background in
- programming at the level of bits and other primitive data
- representations.
-
- 1.3. Scope
-
- The specification specifies a compression method and a file format
- (the latter assuming only that a file can store a sequence of
- arbitrary bytes). It does not specify any particular interface to
- a file system or anything about character sets or encodings
- (except for file names and comments, which are optional).
-
- 1.4. Compliance
-
- Unless otherwise indicated below, a compliant decompressor must be
- able to accept and decompress any file that conforms to all the
- specifications presented here; a compliant compressor must produce
- files that conform to all the specifications presented here. The
- material in the appendices is not part of the specification per se
- and is not relevant to compliance.
-
- 1.5. Definitions of terms and conventions used
-
- byte: 8 bits stored or transmitted as a unit (same as an octet).
- (For this specification, a byte is exactly 8 bits, even on
- machines which store a character on a number of bits different
- from 8.) See below for the numbering of bits within a byte.
-
- 1.6. Changes from previous versions
-
- There have been no technical changes to the gzip format since
- version 4.1 of this specification. In version 4.2, some
- terminology was changed, and the sample CRC code was rewritten for
- clarity and to eliminate the requirement for the caller to do pre-
- and post-conditioning. Version 4.3 is a conversion of the
- specification to RFC style.

-2. Detailed specification
-
- 2.1. Overall conventions
-
- In the diagrams below, a box like this:
-
- +---+
- | | <-- the vertical bars might be missing
- +---+
-
- represents one byte; a box like this:
-
- +==============+
- | |
- +==============+
-
- represents a variable number of bytes.
-
- Bytes stored within a computer do not have a "bit order", since
- they are always treated as a unit. However, a byte considered as
- an integer between 0 and 255 does have a most- and least-
- significant bit, and since we write numbers with the most-
- significant digit on the left, we also write bytes with the most-
- significant bit on the left. In the diagrams below, we number the
- bits of a byte so that bit 0 is the least-significant bit, i.e.,
- the bits are numbered:
-
- +--------+
- |76543210|
- +--------+
-
- This document does not address the issue of the order in which
- bits of a byte are transmitted on a bit-sequential medium, since
- the data format described here is byte- rather than bit-oriented.
-
- Within a computer, a number may occupy multiple bytes. All
- multi-byte numbers in the format described here are stored with
- the least-significant byte first (at the lower memory address).
- For example, the decimal number 520 is stored as:
-
- 0 1
- +--------+--------+
- |00001000|00000010|
- +--------+--------+
- ^ ^
- | |
- | + more significant byte = 2 x 256
- + less significant byte = 8

-
-
- 2.2. File format
-
- A gzip file consists of a series of "members" (compressed data
- sets). The format of each member is specified in the following
- section. The members simply appear one after another in the file,
- with no additional information before, between, or after them.
-
- 2.3. Member format
-
- Each member has the following structure:
-
- +---+---+---+---+---+---+---+---+---+---+
- |ID1|ID2|CM |FLG| MTIME |XFL|OS | (more-->)
- +---+---+---+---+---+---+---+---+---+---+
-
- (if FLG.FEXTRA set)
-
- +---+---+=================================+
- | XLEN |...XLEN bytes of "extra field"...| (more-->)
- +---+---+=================================+
-
- (if FLG.FNAME set)
-
- +=========================================+
- |...original file name, zero-terminated...| (more-->)
- +=========================================+
-
- (if FLG.FCOMMENT set)
-
- +===================================+
- |...file comment, zero-terminated...| (more-->)
- +===================================+
-
- (if FLG.FHCRC set)
-
- +---+---+
- | CRC16 |
- +---+---+
-
- +=======================+
- |...compressed blocks...| (more-->)
- +=======================+
-
- 0 1 2 3 4 5 6 7
- +---+---+---+---+---+---+---+---+
- | CRC32 | ISIZE |
- +---+---+---+---+---+---+---+---+

-
-
- 2.3.1. Member header and trailer
-
- ID1 (IDentification 1)
- ID2 (IDentification 2)
- These have the fixed values ID1 = 31 (0x1f, \037), ID2 = 139
- (0x8b, \213), to identify the file as being in gzip format.
-
- CM (Compression Method)
- This identifies the compression method used in the file. CM
- = 0-7 are reserved. CM = 8 denotes the "deflate"
- compression method, which is the one customarily used by
- gzip and which is documented elsewhere.
-
- FLG (FLaGs)
- This flag byte is divided into individual bits as follows:
-
- bit 0 FTEXT
- bit 1 FHCRC
- bit 2 FEXTRA
- bit 3 FNAME
- bit 4 FCOMMENT
- bit 5 reserved
- bit 6 reserved
- bit 7 reserved
-
- If FTEXT is set, the file is probably ASCII text. This is
- an optional indication, which the compressor may set by
- checking a small amount of the input data to see whether any
- non-ASCII characters are present. In case of doubt, FTEXT
- is cleared, indicating binary data. For systems which have
- different file formats for ascii text and binary data, the
- decompressor can use FTEXT to choose the appropriate format.
- We deliberately do not specify the algorithm used to set
- this bit, since a compressor always has the option of
- leaving it cleared and a decompressor always has the option
- of ignoring it and letting some other program handle issues
- of data conversion.
-
- If FHCRC is set, a CRC16 for the gzip header is present,
- immediately before the compressed data. The CRC16 consists
- of the two least significant bytes of the CRC32 for all
- bytes of the gzip header up to and not including the CRC16.
- [The FHCRC bit was never set by versions of gzip up to
- 1.2.4, even though it was documented with a different
- meaning in gzip 1.2.4.]
-
- If FEXTRA is set, optional extra fields are present, as
- described in a following section.
-
-
-
-Deutsch Informational [Page 6]
-
-RFC 1952 GZIP File Format Specification May 1996
-
-
- If FNAME is set, an original file name is present,
- terminated by a zero byte. The name must consist of ISO
- 8859-1 (LATIN-1) characters; on operating systems using
- EBCDIC or any other character set for file names, the name
- must be translated to the ISO LATIN-1 character set. This
- is the original name of the file being compressed, with any
- directory components removed, and, if the file being
- compressed is on a file system with case insensitive names,
- forced to lower case. There is no original file name if the
- data was compressed from a source other than a named file;
- for example, if the source was stdin on a Unix system, there
- is no file name.
-
- If FCOMMENT is set, a zero-terminated file comment is
- present. This comment is not interpreted; it is only
- intended for human consumption. The comment must consist of
- ISO 8859-1 (LATIN-1) characters. Line breaks should be
- denoted by a single line feed character (10 decimal).
-
- Reserved FLG bits must be zero.
-
- MTIME (Modification TIME)
- This gives the most recent modification time of the original
- file being compressed. The time is in Unix format, i.e.,
- seconds since 00:00:00 GMT, Jan. 1, 1970. (Note that this
- may cause problems for MS-DOS and other systems that use
- local rather than Universal time.) If the compressed data
- did not come from a file, MTIME is set to the time at which
- compression started. MTIME = 0 means no time stamp is
- available.
-
- XFL (eXtra FLags)
- These flags are available for use by specific compression
- methods. The "deflate" method (CM = 8) sets these flags as
- follows:
-
- XFL = 2 - compressor used maximum compression,
- slowest algorithm
- XFL = 4 - compressor used fastest algorithm
-
- OS (Operating System)
- This identifies the type of file system on which compression
- took place. This may be useful in determining end-of-line
- convention for text files. The currently defined values are
- as follows:
-
-
-
-

- 11 - NTFS filesystem (NT)
- 12 - QDOS
- 13 - Acorn RISCOS
- 255 - unknown
-
- XLEN (eXtra LENgth)
- If FLG.FEXTRA is set, this gives the length of the optional
- extra field. See below for details.
-
- CRC32 (CRC-32)
- This contains a Cyclic Redundancy Check value of the
- uncompressed data computed according to CRC-32 algorithm
- used in the ISO 3309 standard and in section 8.1.1.6.2 of
- ITU-T recommendation V.42. (See http://www.iso.ch for
- ordering ISO documents. See gopher://info.itu.ch for an
- online version of ITU-T V.42.)
-
- ISIZE (Input SIZE)
- This contains the size of the original (uncompressed) input
- data modulo 2^32.
-
- 2.3.1.1. Extra field
-
- If the FLG.FEXTRA bit is set, an "extra field" is present in
- the header, with total length XLEN bytes. It consists of a
- series of subfields, each of the form:
-
- +---+---+---+---+==================================+
- |SI1|SI2| LEN |... LEN bytes of subfield data ...|
- +---+---+---+---+==================================+
-
- SI1 and SI2 provide a subfield ID, typically two ASCII letters
- with some mnemonic value. Jean-Loup Gailly
- <gzip@prep.ai.mit.edu> is maintaining a registry of subfield
- IDs; please send him any subfield ID you wish to use. Subfield
- IDs with SI2 = 0 are reserved for future use. The following
- IDs are currently defined:
-
-
-
-Deutsch Informational [Page 8]
-
-RFC 1952 GZIP File Format Specification May 1996
-
-
- SI1 SI2 Data
- ---------- ---------- ----
- 0x41 ('A') 0x70 ('P') Apollo file type information
-
- LEN gives the length of the subfield data, excluding the 4
- initial bytes.
-
- 2.3.1.2. Compliance
-
- A compliant compressor must produce files with correct ID1,
- ID2, CM, CRC32, and ISIZE, but may set all the other fields in
- the fixed-length part of the header to default values (255 for
- OS, 0 for all others). The compressor must set all reserved
- bits to zero.
-
- A compliant decompressor must check ID1, ID2, and CM, and
- provide an error indication if any of these have incorrect
- values. It must examine FEXTRA/XLEN, FNAME, FCOMMENT and FHCRC
- at least so it can skip over the optional fields if they are
- present. It need not examine any other part of the header or
- trailer; in particular, a decompressor may ignore FTEXT and OS
- and always produce binary output, and still be compliant. A
- compliant decompressor must give an error indication if any
- reserved bit is non-zero, since such a bit could indicate the
- presence of a new field that would cause subsequent data to be
- interpreted incorrectly.

-7. Appendix: Jean-Loup Gailly's gzip utility
-
- The most widely used implementation of gzip compression, and the
- original documentation on which this specification is based, were
- created by Jean-Loup Gailly <gzip@prep.ai.mit.edu>. Since this
- implementation is a de facto standard, we mention some more of its
- features here. Again, the material in this section is not part of
- the specification per se, and implementations need not follow it to
- be compliant.
-
- When compressing or decompressing a file, gzip preserves the
- protection, ownership, and modification time attributes on the local
- file system, since there is no provision for representing protection

- unsigned quantity, as here, right shift inserts zero
- bit(s) at the left.
- ! Logical NOT operator.
- ++ "n++" increments the variable n.
- 0xNNN 0x introduces a hexadecimal (base 16) constant.
- Suffix L indicates a long value (at least 32 bits).

-A Fast Method for Identifying Plain Text Files
-==============================================
-
-
-Introduction
-------------
-
-Given a file coming from an unknown source, it is sometimes desirable
-to find out whether the format of that file is plain text. Although
-this may appear like a simple task, a fully accurate detection of the
-file type requires heavy-duty semantic analysis on the file contents.
-It is, however, possible to obtain satisfactory results by employing
-various heuristics.
-
-Previous versions of PKZip and other zip-compatible compression tools
-were using a crude detection scheme: if more than 80% (4/5) of the bytes
-found in a certain buffer are within the range [7..127], the file is
-labeled as plain text, otherwise it is labeled as binary. A prominent
-limitation of this scheme is the restriction to Latin-based alphabets.
-Other alphabets, like Greek, Cyrillic or Asian, make extensive use of
-the bytes within the range [128..255], and texts using these alphabets
-are most often misidentified by this scheme; in other words, the rate
-of false negatives is sometimes too high, which means that the recall
-is low. Another weakness of this scheme is a reduced precision, due to
-the false positives that may occur when binary files containing large
-amounts of textual characters are misidentified as plain text.
-
-In this article we propose a new, simple detection scheme that features
-a much increased precision and a near-100% recall. This scheme is
-designed to work on ASCII, Unicode and other ASCII-derived alphabets,
-and it handles single-byte encodings (ISO-8859, MacRoman, KOI8, etc.)
-and variable-sized encodings (ISO-2022, UTF-8, etc.). Wider encodings
-(UCS-2/UTF-16 and UCS-4/UTF-32) are not handled, however.
-
-
-The Algorithm
--------------
-
-The algorithm works by dividing the set of bytecodes [0..255] into three
-categories:
-- The white list of textual bytecodes:
- 9 (TAB), 10 (LF), 13 (CR), 32 (SPACE) to 255.
-- The gray list of tolerated bytecodes:
- 7 (BEL), 8 (BS), 11 (VT), 12 (FF), 26 (SUB), 27 (ESC).
-- The black list of undesired, non-textual bytecodes:
- 0 (NUL) to 6, 14 to 31.
-
-If a file contains at least one byte that belongs to the white list and
-no byte that belongs to the black list, then the file is categorized as
-plain text; otherwise, it is categorized as binary. (The boundary case,
-when the file is empty, automatically falls into the latter category.)
-
-
-Rationale
----------
-
-The idea behind this algorithm relies on two observations.
-
-The first observation is that, although the full range of 7-bit codes
-[0..127] is properly specified by the ASCII standard, most control
-characters in the range [0..31] are not used in practice. The only
-widely-used, almost universally-portable control codes are 9 (TAB),
-10 (LF) and 13 (CR). There are a few more control codes that are
-recognized on a reduced range of platforms and text viewers/editors:
-7 (BEL), 8 (BS), 11 (VT), 12 (FF), 26 (SUB) and 27 (ESC); but these
-codes are rarely (if ever) used alone, without being accompanied by
-some printable text. Even the newer, portable text formats such as
-XML avoid using control characters outside the list mentioned here.
-
-The second observation is that most of the binary files tend to contain
-control characters, especially 0 (NUL). Even though the older text
-detection schemes observe the presence of non-ASCII codes from the range
-[128..255], the precision rarely has to suffer if this upper range is
-labeled as textual, because the files that are genuinely binary tend to
-contain both control characters and codes from the upper range. On the
-other hand, the upper range needs to be labeled as textual, because it
-is used by virtually all ASCII extensions. In particular, this range is
-used for encoding non-Latin scripts.
-
-Since there is no counting involved, other than simply observing the
-presence or the absence of some byte values, the algorithm produces
-consistent results, regardless what alphabet encoding is being used.
-(If counting were involved, it could be possible to obtain different
-results on a text encoded, say, using ISO-8859-16 versus UTF-8.)
-
-There is an extra category of plain text files that are "polluted" with
-one or more black-listed codes, either by mistake or by peculiar design
-considerations. In such cases, a scheme that tolerates a small fraction
-of black-listed codes would provide an increased recall (i.e. more true
-positives). This, however, incurs a reduced precision overall, since
-false positives are more likely to appear in binary files that contain
-large chunks of textual data. Furthermore, "polluted" plain text should
-be regarded as binary by general-purpose text detection schemes, because
-general-purpose text processing algorithms might not be applicable.
-Under this premise, it is safe to say that our detection method provides
-a near-100% recall.
-
-Experiments have been run on many files coming from various platforms
-and applications. We tried plain text files, system logs, source code,
-formatted office documents, compiled object code, etc. The results
-confirm the optimistic assumptions about the capabilities of this
-algorithm.

-/*
- Examine all possible Huffman codes for a given number of symbols and a
- maximum code length in bits to determine the maximum table size for zilb's
- inflate. Only complete Huffman codes are counted.
-
- Two codes are considered distinct if the vectors of the number of codes per
- length are not identical. So permutations of the symbol assignments result
- in the same code for the counting, as do permutations of the assignments of
- the bit values to the codes (i.e. only canonical codes are counted).
-
- We build a code from shorter to longer lengths, determining how many symbols
- are coded at each length. At each step, we have how many symbols remain to
- be coded, what the last code length used was, and how many bit patterns of
- that length remain unused. Then we add one to the code length and double the
- number of unused patterns to graduate to the next code length. We then
- assign all portions of the remaining symbols to that code length that
- preserve the properties of a correct and eventually complete code. Those
- properties are: we cannot use more bit patterns than are available; and when
- all the symbols are used, there are exactly zero possible bit patterns
- remaining.
-
- The inflate Huffman decoding algorithm uses two-level lookup tables for
- speed. There is a single first-level table to decode codes up to root bits
- in length (root == 9 in the current inflate implementation). The table
- has 1 << root entries and is indexed by the next root bits of input. Codes
- shorter than root bits have replicated table entries, so that the correct
- entry is pointed to regardless of the bits that follow the short code. If
- the code is longer than root bits, then the table entry points to a second-
- level table. The size of that table is determined by the longest code with
- that root-bit prefix. If that longest code has length len, then the table
- has size 1 << (len - root), to index the remaining bits in that set of
- codes. Each subsequent root-bit prefix then has its own sub-table. The
- total number of table entries required by the code is calculated
- incrementally as the number of codes at each bit length is populated. When
- all of the codes are shorter than root bits, then root is reduced to the
- longest code length, resulting in a single, smaller, one-level table.
-
- The inflate algorithm also provides for small values of root (relative to
- the log2 of the number of symbols), where the shortest code has more bits
- than root. In that case, root is increased to the length of the shortest
- code. This program, by design, does not handle that case, so it is verified
- that the number of symbols is less than 2^(root + 1).
-
- In order to speed up the examination (by about ten orders of magnitude for
- the default arguments), the intermediate states in the build-up of a code
- are remembered and previously visited branches are pruned. The memory
- required for this will increase rapidly with the total number of symbols and
- the maximum code length in bits. However this is a very small price to pay
- for the vast speedup.
-
- First, all of the possible Huffman codes are counted, and reachable
- intermediate states are noted by a non-zero count in a saved-results array.
- Second, the intermediate states that lead to (root + 1) bit or longer codes
- are used to look at all sub-codes from those junctures for their inflate
- memory usage. (The amount of memory used is not affected by the number of
- codes of root bits or less in length.) Third, the visited states in the
- construction of those sub-codes and the associated calculation of the table
- size is recalled in order to avoid recalculating from the same juncture.
- Beginning the code examination at (root + 1) bit codes, which is enabled by
- identifying the reachable nodes, accounts for about six of the orders of
- magnitude of improvement for the default arguments. About another four
- orders of magnitude come from not revisiting previous states. Out of
- approximately 2x10^16 possible Huffman codes, only about 2x10^6 sub-codes
- need to be examined to cover all of the possible table memory usage cases
- for the default arguments of 286 symbols limited to 15-bit codes.
-
- Note that an unsigned long long type is used for counting. It is quite easy
- to exceed the capacity of an eight-byte integer with a large number of
- symbols and a large maximum code length, so multiple-precision arithmetic
- would need to replace the unsigned long long arithmetic in that case. This
- program will abort if an overflow occurs. The big_t type identifies where
- the counting takes place.
-
- An unsigned long long type is also used for calculating the number of
- possible codes remaining at the maximum length. This limits the maximum
- code length to the number of bits in a long long minus the number of bits
- needed to represent the symbols in a flat code. The code_t type identifies
- where the bit pattern counting takes place.

- gzlog provides a mechanism for frequently appending short strings to a gzip
- file that is efficient both in execution time and compression ratio. The
- strategy is to write the short strings in an uncompressed form to the end of
- the gzip file, only compressing when the amount of uncompressed data has
- reached a given threshold.
-
- gzlog also provides protection against interruptions in the process due to
- system crashes. The status of the operation is recorded in an extra field
- in the gzip file, and is only updated once the gzip file is brought to a
- valid state. The last data to be appended or compressed is saved in an
- auxiliary file, so that if the operation is interrupted, it can be completed
- the next time an append operation is attempted.
-
- gzlog maintains another auxiliary file with the last 32K of data from the
- compressed portion, which is preloaded for the compression of the subsequent
- data. This minimizes the impact to the compression ratio of appending.
- */
-
-/*
- Operations Concept:
-
- Files (log name "foo"):
- foo.gz -- gzip file with the complete log
- foo.add -- last message to append or last data to compress
- foo.dict -- dictionary of the last 32K of data for next compression
- foo.temp -- temporary dictionary file for compression after this one
- foo.lock -- lock file for reading and writing the other files
- foo.repairs -- log file for log file recovery operations (not compressed)
-
- gzip file structure:
- - fixed-length (no file name) header with extra field (see below)
- - compressed data ending initially with empty stored block
- - uncompressed data filling out originally empty stored block and
- subsequent stored blocks as needed (16K max each)
- - gzip trailer
- - no junk at end (no other gzip streams)
-
- When appending data, the information in the first three items above plus the
- foo.add file are sufficient to recover an interrupted append operation. The
- extra field has the necessary information to restore the start of the last
- stored block and determine where to append the data in the foo.add file, as
- well as the crc and length of the gzip data before the append operation.
-
- The foo.add file is created before the gzip file is marked for append, and
- deleted after the gzip file is marked as complete. So if the append
- operation is interrupted, the data to add will still be there. If due to
- some external force, the foo.add file gets deleted between when the append
- operation was interrupted and when recovery is attempted, the gzip file will
- still be restored, but without the appended data.
-
- When compressing data, the information in the first two items above plus the
- foo.add file are sufficient to recover an interrupted compress operation.
- The extra field has the necessary information to find the end of the
- compressed data, and contains both the crc and length of just the compressed
- data and of the complete set of data including the contents of the foo.add
- file.
-
- Again, the foo.add file is maintained during the compress operation in case
- of an interruption. If in the unlikely event the foo.add file with the data
- to be compressed is missing due to some external force, a gzip file with
- just the previous compressed data will be reconstructed. In this case, all
- of the data that was to be compressed is lost (approximately one megabyte).
- This will not occur if all that happened was an interruption of the compress
- operation.
-
- The third state that is marked is the replacement of the old dictionary with
- the new dictionary after a compress operation. Once compression is
- complete, the gzip file is marked as being in the replace state. This
- completes the gzip file, so an interrupt after being so marked does not
- result in recompression. Then the dictionary file is replaced, and the gzip
- file is marked as completed. This state prevents the possibility of
- restarting compression with the wrong dictionary file.
-
- All three operations are wrapped by a lock/unlock procedure. In order to
- gain exclusive access to the log files, first a foo.lock file must be
- exclusively created. When all operations are complete, the lock is
- released by deleting the foo.lock file. If when attempting to create the
- lock file, it already exists and the modify time of the lock file is more
- than five minutes old (set by the PATIENCE define below), then the old
- lock file is considered stale and deleted, and the exclusive creation of
- the lock file is retried. To assure that there are no false assessments
- of the staleness of the lock file, the operations periodically touch the
- lock file to update the modified date.
-
- Following is the definition of the extra field with all of the information
- required to enable the above append and compress operations and their
- recovery if interrupted. Multi-byte values are stored little endian
- (consistent with the gzip format). File pointers are eight bytes long.
- The crc's and lengths for the gzip trailer are four bytes long. (Note that
- the length at the end of a gzip file is used for error checking only, and
- for large files is actually the length modulo 2^32.) The stored block
- length is two bytes long. The gzip extra field two-byte identification is
- "ap" for append. It is assumed that writing the extra field to the file is
- an "atomic" operation. That is, either all of the extra field is written
- to the file, or none of it is, if the operation is interrupted right at the
- point of updating the extra field. This is a reasonable assumption, since
- the extra field is within the first 52 bytes of the file, which is smaller
- than any expected block size for a mass storage device (usually 512 bytes or
- larger).
-
- Extra field (35 bytes):
- - Pointer to first stored block length -- this points to the two-byte length
- of the first stored block, which is followed by the two-byte, one's
- complement of that length. The stored block length is preceded by the
- three-bit header of the stored block, which is the actual start of the
- stored block in the deflate format. See the bit offset field below.
- - Pointer to the last stored block length. This is the same as above, but
- for the last stored block of the uncompressed data in the gzip file.
- Initially this is the same as the first stored block length pointer.
- When the stored block gets to 16K (see the MAX_STORE define), then a new
- stored block as added, at which point the last stored block length pointer
- is different from the first stored block length pointer. When they are
- different, the first bit of the last stored block header is eight bits, or
- one byte back from the block length.
- - Compressed data crc and length. This is the crc and length of the data
- that is in the compressed portion of the deflate stream. These are used
- only in the event that the foo.add file containing the data to compress is
- lost after a compress operation is interrupted.
- - Total data crc and length. This is the crc and length of all of the data
- stored in the gzip file, compressed and uncompressed. It is used to
- reconstruct the gzip trailer when compressing, as well as when recovering
- interrupted operations.
- - Final stored block length. This is used to quickly find where to append,
- and allows the restoration of the original final stored block state when
- an append operation is interrupted.
- - First stored block start as the number of bits back from the final stored
- block first length byte. This value is in the range of 3..10, and is
- stored as the low three bits of the final byte of the extra field after
- subtracting three (0..7). This allows the last-block bit of the stored
- block header to be updated when a new stored block is added, for the case
- when the first stored block and the last stored block are the same. (When
- they are different, the numbers of bits back is known to be eight.) This
- also allows for new compressed data to be appended to the old compressed
- data in the compress operation, overwriting the previous first stored
- block, or for the compressed data to be terminated and a valid gzip file
- reconstructed on the off chance that a compression operation was
- interrupted and the data to compress in the foo.add file was deleted.
- - The operation in process. This is the next two bits in the last byte (the
- bits under the mask 0x18). The are interpreted as 0: nothing in process,
- 1: append in process, 2: compress in process, 3: replace in process.
- - The top three bits of the last byte in the extra field are reserved and
- are currently set to zero.
-
- Main procedure:
- - Exclusively create the foo.lock file using the O_CREAT and O_EXCL modes of
- the system open() call. If the modify time of an existing lock file is
- more than PATIENCE seconds old, then the lock file is deleted and the
- exclusive create is retried.
- - Load the extra field from the foo.gz file, and see if an operation was in
- progress but not completed. If so, apply the recovery procedure below.
- - Perform the append procedure with the provided data.
- - If the uncompressed data in the foo.gz file is 1MB or more, apply the
- compress procedure.
- - Delete the foo.lock file.
-
- Append procedure:
- - Put what to append in the foo.add file so that the operation can be
- restarted if this procedure is interrupted.
- - Mark the foo.gz extra field with the append operation in progress.
- + Restore the original last-block bit and stored block length of the last
- stored block from the information in the extra field, in case a previous
- append operation was interrupted.
- - Append the provided data to the last stored block, creating new stored
- blocks as needed and updating the stored blocks last-block bits and
- lengths.
- - Update the crc and length with the new data, and write the gzip trailer.
- - Write over the extra field (with a single write operation) with the new
- pointers, lengths, and crc's, and mark the gzip file as not in process.
- Though there is still a foo.add file, it will be ignored since nothing
- is in process. If a foo.add file is leftover from a previously
- completed operation, it is truncated when writing new data to it.
- - Delete the foo.add file.
-
- Compress and replace procedures:
- - Read all of the uncompressed data in the stored blocks in foo.gz and write
- it to foo.add. Also write foo.temp with the last 32K of that data to
- provide a dictionary for the next invocation of this procedure.
- - Rewrite the extra field marking foo.gz with a compression in process.
- * If there is no data provided to compress (due to a missing foo.add file
- when recovering), reconstruct and truncate the foo.gz file to contain
- only the previous compressed data and proceed to the step after the next
- one. Otherwise ...
- - Compress the data with the dictionary in foo.dict, and write to the
- foo.gz file starting at the bit immediately following the last previously
- compressed block. If there is no foo.dict, proceed anyway with the
- compression at slightly reduced efficiency. (For the foo.dict file to be
- missing requires some external failure beyond simply the interruption of
- a compress operation.) During this process, the foo.lock file is
- periodically touched to assure that that file is not considered stale by
- another process before we're done. The deflation is terminated with a
- non-last empty static block (10 bits long), that is then located and
- written over by a last-bit-set empty stored block.
- - Append the crc and length of the data in the gzip file (previously
- calculated during the append operations).
- - Write over the extra field with the updated stored block offsets, bits
- back, crc's, and lengths, and mark foo.gz as in process for a replacement
- of the dictionary.
- @ Delete the foo.add file.
- - Replace foo.dict with foo.temp.
- - Write over the extra field, marking foo.gz as complete.
-
- Recovery procedure:
- - If not a replace recovery, read in the foo.add file, and provide that data
- to the appropriate recovery below. If there is no foo.add file, provide
- a zero data length to the recovery. In that case, the append recovery
- restores the foo.gz to the previous compressed + uncompressed data state.
- For the the compress recovery, a missing foo.add file results in foo.gz
- being restored to the previous compressed-only data state.
- - Append recovery:
- - Pick up append at + step above
- - Compress recovery:
- - Pick up compress at * step above
- - Replace recovery:
- - Pick up compress at @ step above
- - Log the repair with a date stamp in foo.repairs

- The gzlog object allows writing short messages to a gzipped log file,
- opening the log file locked for small bursts, and then closing it. The log
- object works by appending stored (uncompressed) data to the gzip file until
- 1 MB has been accumulated. At that time, the stored data is compressed, and
- replaces the uncompressed data in the file. The log file is truncated to
- its new size at that time. After each write operation, the log file is a
- valid gzip file that can decompressed to recover what was written.
-
- The gzlog operations can be interupted at any point due to an application or
- system crash, and the log file will be recovered the next time the log is
- opened with gzlog_open().

- Process a set of code lengths to create a canonical Huffman code. The
- code lengths are lens[0..codes-1]. Each length corresponds to the
- symbols 0..codes-1. The Huffman code is generated by first sorting the
- symbols by length from short to long, and retaining the symbol order
- for codes with equal lengths. Then the code starts with all zero bits
- for the first code of the shortest length, and the codes are integer
- increments for the same length, and zeros are appended as the length
- increases. For the deflate format, these bits are stored backwards
- from their more natural integer increment ordering, and so when the
- decoding tables are built in the large loop below, the integer codes
- are incremented backwards.
-
- This routine assumes, but does not check, that all of the entries in
- lens[] are in the range 0..MAXBITS. The caller must assure this.
- 1..MAXBITS is interpreted as that code length. zero means that that
- symbol does not occur in this code.
-
- The codes are sorted by computing a count of codes for each length,
- creating from that a table of starting indices for each length in the
- sorted table, and then entering the symbols in order in the sorted
- table. The sorted table is work[], with that space being provided by
- the caller.
-
- The length counts are used for other purposes as well, i.e. finding
- the minimum and maximum length codes, determining if there are any
- codes at all, checking for a valid set of lengths, and looking ahead
- at length counts to determine sub-table sizes when building the

- Create and fill in decoding tables. In this loop, the table being

- bits off of the bottom. For codes where len is less than drop + curr,
- those top drop + curr - len bits are incremented through all values to
- fill the table with replicated entries.
-
- root is the number of index bits for the root table. When len exceeds
- root, sub-tables are created pointed to by the root entry with an index
- of the low root bits of huff. This is saved in low to check for when a
- new sub-table should be started. drop is zero when the root table is
- being filled, and drop is root when sub-tables are being filled.
-
- When a new sub-table is needed, it is necessary to look ahead in the
- code lengths to determine what size sub-table is needed. The length
- counts are used for this, and so count[] is decremented as codes are
- entered in the tables.
-
- used keeps track of how many table entries have been allocated from the
- provided *table space. It is checked for LENS and DIST tables against
- the constants ENOUGH_LENS and ENOUGH_DISTS to guard against changes in
- the initial root table size constants. See the comments in inftrees.h
- for more information.

- sym increments through all symbols, and the loop terminates when

-See below some functions declarations for Visual Basic.
-
-Frequently Asked Question:
-
-Q: Each time I use the compress function I get the -5 error (not enough
- room in the output buffer).
-
-A: Make sure that the length of the compressed buffer is passed by
- reference ("as any"), not by value ("as long"). Also check that
- before the call of compress this length is equal to the total size of
- the compressed buffer and not zero.

- These memory tracking routines are provided to zlib and track all of zlib's
- allocations and deallocations, check for LIFO operations, keep a current
- and high water mark of total bytes requested, optionally set a limit on the
- total memory that can be allocated, and when done check for memory leaks.
-
- They are used as follows:
-
- z_stream strm;
- mem_setup(&strm) initializes the memory tracking and sets the
- zalloc, zfree, and opaque members of strm to use
- memory tracking for all zlib operations on strm
- mem_limit(&strm, limit) sets a limit on the total bytes requested -- a
- request that exceeds this limit will result in an
- allocation failure (returns NULL) -- setting the
- limit to zero means no limit, which is the default
- after mem_setup()
- mem_used(&strm, "msg") prints to stderr "msg" and the total bytes used
- mem_high(&strm, "msg") prints to stderr "msg" and the high water mark
- mem_done(&strm, "msg") ends memory tracking, releases all allocations
- for the tracking as well as leaked zlib blocks, if
- any. If there was anything unusual, such as leaked
- blocks, non-FIFO frees, or frees of addresses not
- allocated, then "msg" and information about the
- problem is printed to stderr. If everything is
- normal, nothing is printed. mem_done resets the
- strm members to Z_NULL to use the default memory
- allocation routines on the next zlib initialization
- using strm.

- Frequently Asked Questions about ZLIB1.DLL
-
-
-This document describes the design, the rationale, and the usage
-of the official DLL build of zlib, named ZLIB1.DLL. If you have
-general questions about zlib, you should see the file "FAQ" found
-in the zlib distribution, or at the following location:
- http://www.gzip.org/zlib/zlib_faq.html
-
-
- 1. What is ZLIB1.DLL, and how can I get it?
-
- - ZLIB1.DLL is the official build of zlib as a DLL.
- (Please remark the character '1' in the name.)
-
- Pointers to a precompiled ZLIB1.DLL can be found in the zlib
- web site at:
- http://www.zlib.net/
-
- Applications that link to ZLIB1.DLL can rely on the following
- specification:
-
- * The exported symbols are exclusively defined in the source
- files "zlib.h" and "zlib.def", found in an official zlib
- source distribution.
- * The symbols are exported by name, not by ordinal.
- * The exported names are undecorated.
- * The calling convention of functions is "C" (CDECL).
- * The ZLIB1.DLL binary is linked to MSVCRT.DLL.
-
- The archive in which ZLIB1.DLL is bundled contains compiled
- test programs that must run with a valid build of ZLIB1.DLL.
- It is recommended to download the prebuilt DLL from the zlib
- web site, instead of building it yourself, to avoid potential
- incompatibilities that could be introduced by your compiler
- and build settings. If you do build the DLL yourself, please
- make sure that it complies with all the above requirements,
- and it runs with the precompiled test programs, bundled with
- the original ZLIB1.DLL distribution.
-
- If, for any reason, you need to build an incompatible DLL,
- please use a different file name.
-
-
- 2. Why did you change the name of the DLL to ZLIB1.DLL?
- What happened to the old ZLIB.DLL?
-
- - The old ZLIB.DLL, built from zlib-1.1.4 or earlier, required
- compilation settings that were incompatible to those used by
- a static build. The DLL settings were supposed to be enabled
- by defining the macro ZLIB_DLL, before including "zlib.h".
- Incorrect handling of this macro was silently accepted at
- build time, resulting in two major problems:
-
- * ZLIB_DLL was missing from the old makefile. When building
- the DLL, not all people added it to the build options. In
- consequence, incompatible incarnations of ZLIB.DLL started
- to circulate around the net.
-
- * When switching from using the static library to using the
- DLL, applications had to define the ZLIB_DLL macro and
- to recompile all the sources that contained calls to zlib
- functions. Failure to do so resulted in creating binaries
- that were unable to run with the official ZLIB.DLL build.
-
- The only possible solution that we could foresee was to make
- a binary-incompatible change in the DLL interface, in order to
- remove the dependency on the ZLIB_DLL macro, and to release
- the new DLL under a different name.
-
- We chose the name ZLIB1.DLL, where '1' indicates the major
- zlib version number. We hope that we will not have to break
- the binary compatibility again, at least not as long as the
- zlib-1.x series will last.
-
- There is still a ZLIB_DLL macro, that can trigger a more
- efficient build and use of the DLL, but compatibility no
- longer dependents on it.
-
-
- 3. Can I build ZLIB.DLL from the new zlib sources, and replace
- an old ZLIB.DLL, that was built from zlib-1.1.4 or earlier?
-
- - In principle, you can do it by assigning calling convention
- keywords to the macros ZEXPORT and ZEXPORTVA. In practice,
- it depends on what you mean by "an old ZLIB.DLL", because the
- old DLL exists in several mutually-incompatible versions.
- You have to find out first what kind of calling convention is
- being used in your particular ZLIB.DLL build, and to use the
- same one in the new build. If you don't know what this is all
- about, you might be better off if you would just leave the old
- DLL intact.
-
-
- 4. Can I compile my application using the new zlib interface, and
- link it to an old ZLIB.DLL, that was built from zlib-1.1.4 or
- earlier?
-
- - The official answer is "no"; the real answer depends again on
- what kind of ZLIB.DLL you have. Even if you are lucky, this
- course of action is unreliable.
-
- If you rebuild your application and you intend to use a newer
- version of zlib (post- 1.1.4), it is strongly recommended to
- link it to the new ZLIB1.DLL.
-
-
- 5. Why are the zlib symbols exported by name, and not by ordinal?
-
- - Although exporting symbols by ordinal is a little faster, it
- is risky. Any single glitch in the maintenance or use of the
- DEF file that contains the ordinals can result in incompatible
- builds and frustrating crashes. Simply put, the benefits of
- exporting symbols by ordinal do not justify the risks.
-
- Technically, it should be possible to maintain ordinals in
- the DEF file, and still export the symbols by name. Ordinals
- exist in every DLL, and even if the dynamic linking performed
- at the DLL startup is searching for names, ordinals serve as
- hints, for a faster name lookup. However, if the DEF file
- contains ordinals, the Microsoft linker automatically builds
- an implib that will cause the executables linked to it to use
- those ordinals, and not the names. It is interesting to
- notice that the GNU linker for Win32 does not suffer from this
- problem.
-
- It is possible to avoid the DEF file if the exported symbols
- are accompanied by a "__declspec(dllexport)" attribute in the
- source files. You can do this in zlib by predefining the
- ZLIB_DLL macro.
-
-
- 6. I see that the ZLIB1.DLL functions use the "C" (CDECL) calling
- convention. Why not use the STDCALL convention?
- STDCALL is the standard convention in Win32, and I need it in
- my Visual Basic project!
-
- (For readability, we use CDECL to refer to the convention
- triggered by the "__cdecl" keyword, STDCALL to refer to
- the convention triggered by "__stdcall", and FASTCALL to
- refer to the convention triggered by "__fastcall".)
-
- - Most of the native Windows API functions (without varargs) use
- indeed the WINAPI convention (which translates to STDCALL in
- Win32), but the standard C functions use CDECL. If a user
- application is intrinsically tied to the Windows API (e.g.
- it calls native Windows API functions such as CreateFile()),
- sometimes it makes sense to decorate its own functions with
- WINAPI. But if ANSI C or POSIX portability is a goal (e.g.
- it calls standard C functions such as fopen()), it is not a
- sound decision to request the inclusion of <windows.h>, or to
- use non-ANSI constructs, for the sole purpose to make the user
- functions STDCALL-able.
-
- The functionality offered by zlib is not in the category of
- "Windows functionality", but is more like "C functionality".
-
- Technically, STDCALL is not bad; in fact, it is slightly
- faster than CDECL, and it works with variable-argument
- functions, just like CDECL. It is unfortunate that, in spite
- of using STDCALL in the Windows API, it is not the default
- convention used by the C compilers that run under Windows.
- The roots of the problem reside deep inside the unsafety of
- the K&R-style function prototypes, where the argument types
- are not specified; but that is another story for another day.
-
- The remaining fact is that CDECL is the default convention.
- Even if an explicit convention is hard-coded into the function
- prototypes inside C headers, problems may appear. The
- necessity to expose the convention in users' callbacks is one
- of these problems.
-
- The calling convention issues are also important when using
- zlib in other programming languages. Some of them, like Ada
- (GNAT) and Fortran (GNU G77), have C bindings implemented
- initially on Unix, and relying on the C calling convention.
- On the other hand, the pre- .NET versions of Microsoft Visual
- Basic require STDCALL, while Borland Delphi prefers, although
- it does not require, FASTCALL.
-
- In fairness to all possible uses of zlib outside the C
- programming language, we choose the default "C" convention.
- Anyone interested in different bindings or conventions is
- encouraged to maintain specialized projects. The "contrib/"
- directory from the zlib distribution already holds a couple
- of foreign bindings, such as Ada, C++, and Delphi.
-
-
- 7. I need a DLL for my Visual Basic project. What can I do?
-
- - Define the ZLIB_WINAPI macro before including "zlib.h", when
- building both the DLL and the user application (except that
- you don't need to define anything when using the DLL in Visual
- Basic). The ZLIB_WINAPI macro will switch on the WINAPI
- (STDCALL) convention. The name of this DLL must be different
- than the official ZLIB1.DLL.
-
- Gilles Vollant has contributed a build named ZLIBWAPI.DLL,
- with the ZLIB_WINAPI macro turned on, and with the minizip
- functionality built in. For more information, please read
- the notes inside "contrib/vstudio/readme.txt", found in the
- zlib distribution.
-
-
- 8. I need to use zlib in my Microsoft .NET project. What can I
- do?
-
- - Henrik Ravn has contributed a .NET wrapper around zlib. Look
- into contrib/dotzlib/, inside the zlib distribution.
-
-
- 9. If my application uses ZLIB1.DLL, should I link it to
- MSVCRT.DLL? Why?
-
- - It is not required, but it is recommended to link your
- application to MSVCRT.DLL, if it uses ZLIB1.DLL.
-
- The executables (.EXE, .DLL, etc.) that are involved in the
- same process and are using the C run-time library (i.e. they
- are calling standard C functions), must link to the same
- library. There are several libraries in the Win32 system:
- CRTDLL.DLL, MSVCRT.DLL, the static C libraries, etc.
- Since ZLIB1.DLL is linked to MSVCRT.DLL, the executables that
- depend on it should also be linked to MSVCRT.DLL.
-
-
-10. Why are you saying that ZLIB1.DLL and my application should
- be linked to the same C run-time (CRT) library? I linked my
- application and my DLLs to different C libraries (e.g. my
- application to a static library, and my DLLs to MSVCRT.DLL),
- and everything works fine.
-
- - If a user library invokes only pure Win32 API (accessible via
- <windows.h> and the related headers), its DLL build will work
- in any context. But if this library invokes standard C API,
- things get more complicated.
-
- There is a single Win32 library in a Win32 system. Every
- function in this library resides in a single DLL module, that
- is safe to call from anywhere. On the other hand, there are
- multiple versions of the C library, and each of them has its
- own separate internal state. Standalone executables and user
- DLLs that call standard C functions must link to a C run-time
- (CRT) library, be it static or shared (DLL). Intermixing
- occurs when an executable (not necessarily standalone) and a
- DLL are linked to different CRTs, and both are running in the
- same process.
-
- Intermixing multiple CRTs is possible, as long as their
- internal states are kept intact. The Microsoft Knowledge Base
- articles KB94248 "HOWTO: Use the C Run-Time" and KB140584
- "HOWTO: Link with the Correct C Run-Time (CRT) Library"
- mention the potential problems raised by intermixing.
-
- If intermixing works for you, it's because your application
- and DLLs are avoiding the corruption of each of the CRTs'
- internal states, maybe by careful design, or maybe by fortune.
-
- Also note that linking ZLIB1.DLL to non-Microsoft CRTs, such
- as those provided by Borland, raises similar problems.
-
-
-11. Why are you linking ZLIB1.DLL to MSVCRT.DLL?
-
- - MSVCRT.DLL exists on every Windows 95 with a new service pack
- installed, or with Microsoft Internet Explorer 4 or later, and
- on all other Windows 4.x or later (Windows 98, Windows NT 4,
- or later). It is freely distributable; if not present in the
- system, it can be downloaded from Microsoft or from other
- software provider for free.
-
- The fact that MSVCRT.DLL does not exist on a virgin Windows 95
- is not so problematic. Windows 95 is scarcely found nowadays,
- Microsoft ended its support a long time ago, and many recent
- applications from various vendors, including Microsoft, do not
- even run on it. Furthermore, no serious user should run
- Windows 95 without a proper update installed.
-
-
-12. Why are you not linking ZLIB1.DLL to
- <<my favorite C run-time library>> ?
-
- - We considered and abandoned the following alternatives:
-
- * Linking ZLIB1.DLL to a static C library (LIBC.LIB, or
- LIBCMT.LIB) is not a good option. People are using the DLL
- mainly to save disk space. If you are linking your program
- to a static C library, you may as well consider linking zlib
- in statically, too.
-
- * Linking ZLIB1.DLL to CRTDLL.DLL looks appealing, because
- CRTDLL.DLL is present on every Win32 installation.
- Unfortunately, it has a series of problems: it does not
- work properly with Microsoft's C++ libraries, it does not
- provide support for 64-bit file offsets, (and so on...),
- and Microsoft discontinued its support a long time ago.
-
- * Linking ZLIB1.DLL to MSVCR70.DLL or MSVCR71.DLL, supplied
- with the Microsoft .NET platform, and Visual C++ 7.0/7.1,
- raises problems related to the status of ZLIB1.DLL as a
- system component. According to the Microsoft Knowledge Base
- article KB326922 "INFO: Redistribution of the Shared C
- Runtime Component in Visual C++ .NET", MSVCR70.DLL and
- MSVCR71.DLL are not supposed to function as system DLLs,
- because they may clash with MSVCRT.DLL. Instead, the
- application's installer is supposed to put these DLLs
- (if needed) in the application's private directory.
- If ZLIB1.DLL depends on a non-system runtime, it cannot
- function as a redistributable system component.
-
- * Linking ZLIB1.DLL to non-Microsoft runtimes, such as
- Borland's, or Cygwin's, raises problems related to the
- reliable presence of these runtimes on Win32 systems.
- It's easier to let the DLL build of zlib up to the people
- who distribute these runtimes, and who may proceed as
- explained in the answer to Question 14.
-
-
-13. If ZLIB1.DLL cannot be linked to MSVCR70.DLL or MSVCR71.DLL,
- how can I build/use ZLIB1.DLL in Microsoft Visual C++ 7.0
- (Visual Studio .NET) or newer?
-
- - Due to the problems explained in the Microsoft Knowledge Base
- article KB326922 (see the previous answer), the C runtime that
- comes with the VC7 environment is no longer considered a
- system component. That is, it should not be assumed that this
- runtime exists, or may be installed in a system directory.
- Since ZLIB1.DLL is supposed to be a system component, it may
- not depend on a non-system component.
-
- In order to link ZLIB1.DLL and your application to MSVCRT.DLL
- in VC7, you need the library of Visual C++ 6.0 or older. If
- you don't have this library at hand, it's probably best not to
- use ZLIB1.DLL.
-
- We are hoping that, in the future, Microsoft will provide a
- way to build applications linked to a proper system runtime,
- from the Visual C++ environment. Until then, you have a
- couple of alternatives, such as linking zlib in statically.
- If your application requires dynamic linking, you may proceed
- as explained in the answer to Question 14.
-
-
-14. I need to link my own DLL build to a CRT different than
- MSVCRT.DLL. What can I do?
-
- - Feel free to rebuild the DLL from the zlib sources, and link
- it the way you want. You should, however, clearly state that
- your build is unofficial. You should give it a different file
- name, and/or install it in a private directory that can be
- accessed by your application only, and is not visible to the
- others (i.e. it's neither in the PATH, nor in the SYSTEM or
- SYSTEM32 directories). Otherwise, your build may clash with
- applications that link to the official build.
-
- For example, in Cygwin, zlib is linked to the Cygwin runtime
- CYGWIN1.DLL, and it is distributed under the name CYGZ.DLL.
-
-
-15. May I include additional pieces of code that I find useful,
- link them in ZLIB1.DLL, and export them?
-
- - No. A legitimate build of ZLIB1.DLL must not include code
- that does not originate from the official zlib source code.
- But you can make your own private DLL build, under a different
- file name, as suggested in the previous answer.
-
- For example, zlib is a part of the VCL library, distributed
- with Borland Delphi and C++ Builder. The DLL build of VCL
- is a redistributable file, named VCLxx.DLL.
-
-
-16. May I remove some functionality out of ZLIB1.DLL, by enabling
- macros like NO_GZCOMPRESS or NO_GZIP at compile time?
-
- - No. A legitimate build of ZLIB1.DLL must provide the complete
- zlib functionality, as implemented in the official zlib source
- code. But you can make your own private DLL build, under a
- different file name, as suggested in the previous answer.
-
-
-17. I made my own ZLIB1.DLL build. Can I test it for compliance?
-
- - We prefer that you download the official DLL from the zlib
- web site. If you need something peculiar from this DLL, you
- can send your suggestion to the zlib mailing list.
-
- However, in case you do rebuild the DLL yourself, you can run
- it with the test programs found in the DLL distribution.
- Running these test programs is not a guarantee of compliance,
- but a failure can imply a detected problem.

-ZLIB DATA COMPRESSION LIBRARY
-
-zlib 1.2.7 is a general purpose data compression library. All the code is
-thread safe. The data format used by the zlib library is described by RFCs
-(Request for Comments) 1950 to 1952 in the files
-http://www.ietf.org/rfc/rfc1950.txt (zlib format), rfc1951.txt (deflate format)
-and rfc1952.txt (gzip format).
-
-All functions of the compression library are documented in the file zlib.h
-(volunteer to write man pages welcome, contact zlib@gzip.org). Two compiled
-examples are distributed in this package, example and minigzip. The example_d
-and minigzip_d flavors validate that the zlib1.dll file is working correctly.
-
-Questions about zlib should be sent to <zlib@gzip.org>. The zlib home page
-is http://zlib.net/ . Before reporting a problem, please check this site to
-verify that you have the latest version of zlib; otherwise get the latest
-version and check whether the problem still exists or not.
-
-PLEASE read DLL_FAQ.txt, and the the zlib FAQ http://zlib.net/zlib_faq.html
-before asking for help.
-
-
-Manifest:
-
-The package zlib-1.2.7-win32-x86.zip will contain the following files:
-
- README-WIN32.txt This document
- ChangeLog Changes since previous zlib packages
- DLL_FAQ.txt Frequently asked questions about zlib1.dll
- zlib.3.pdf Documentation of this library in Adobe Acrobat format
-
- example.exe A statically-bound example (using zlib.lib, not the dll)
- example.pdb Symbolic information for debugging example.exe
-
- example_d.exe A zlib1.dll bound example (using zdll.lib)
- example_d.pdb Symbolic information for debugging example_d.exe
-
- minigzip.exe A statically-bound test program (using zlib.lib, not the dll)
- minigzip.pdb Symbolic information for debugging minigzip.exe
-
- minigzip_d.exe A zlib1.dll bound test program (using zdll.lib)
- minigzip_d.pdb Symbolic information for debugging minigzip_d.exe
-
- zlib.h Install these files into the compilers' INCLUDE path to
- zconf.h compile programs which use zlib.lib or zdll.lib
-
- zdll.lib Install these files into the compilers' LIB path if linking
- zdll.exp a compiled program to the zlib1.dll binary
-
- zlib.lib Install these files into the compilers' LIB path to link zlib
- zlib.pdb into compiled programs, without zlib1.dll runtime dependency
- (zlib.pdb provides debugging info to the compile time linker)
-
- zlib1.dll Install this binary shared library into the system PATH, or
- the program's runtime directory (where the .exe resides)
- zlib1.pdb Install in the same directory as zlib1.dll, in order to debug
- an application crash using WinDbg or similar tools.
-
-All .pdb files above are entirely optional, but are very useful to a developer
-attempting to diagnose program misbehavior or a crash. Many additional
-important files for developers can be found in the zlib127.zip source package
-available from http://zlib.net/ - review that package's README file for details.
-
-
-Acknowledgments:
-
-The deflate format used by zlib was defined by Phil Katz. The deflate and
-zlib specifications were written by L. Peter Deutsch. Thanks to all the
-people who reported problems and suggested various improvements in zlib; they
-are too numerous to cite here.

- The 'zlib' compression library provides in-memory compression and
- decompression functions, including integrity checks of the uncompressed data.
- This version of the library supports only one compression method (deflation)
- but other algorithms will be added later and will have the same stream
- interface.
-
- Compression can be done in a single step if the buffers are large enough,
- or can be done by repeated calls of the compression function. In the latter
- case, the application must provide more input and/or consume the output
- (providing more output space) before each call.
-
- The compressed data format used by default by the in-memory functions is
- the zlib format, which is a zlib wrapper documented in RFC 1950, wrapped
- around a deflate stream, which is itself documented in RFC 1951.
-
- The library also supports reading and writing files in gzip (.gz) format
- with an interface similar to that of stdio using the functions that start
- with "gz". The gzip format is different from the zlib format. gzip is a
- gzip wrapper, documented in RFC 1952, wrapped around a deflate stream.
-
- This library can optionally read and write gzip streams in memory as well.
-
- The zlib format was designed to be compact and fast for use in memory
- and on communications channels. The gzip format was designed for single-
- file compression on file systems, has a larger header than zlib to maintain
- directory information, and uses a different, slower check method than zlib.
-
- The library does not install any signal handler. The decoder checks
- the consistency of the compressed data, so the library should never crash
- even in case of corrupted input.

- The fields total_in and total_out can be used for statistics or progress

-ZEXTERN int ZEXPORT deflate OF((z_streamp strm, int flush));
-/*
- deflate compresses as much data as possible, and stops when the input
- buffer becomes empty or the output buffer becomes full. It may introduce
- some output latency (reading input without producing any output) except when
- forced to flush.
-
- The detailed semantics are as follows. deflate performs one or both of the
- following actions:
-
- - Compress more input starting at next_in and update next_in and avail_in
- accordingly. If not all input can be processed (because there is not
- enough room in the output buffer), next_in and avail_in are updated and
- processing will resume at this point for the next call of deflate().
-
- - Provide more output starting at next_out and update next_out and avail_out
- accordingly. This action is forced if the parameter flush is non zero.
- Forcing flush frequently degrades the compression ratio, so this parameter
- should be set only when necessary (in interactive applications). Some
- output may be provided even if flush is not set.
-
- Before the call of deflate(), the application should ensure that at least
- one of the actions is possible, by providing more input and/or consuming more
- output, and updating avail_in or avail_out accordingly; avail_out should
- never be zero before the call. The application can consume the compressed
- output when it wants, for example when the output buffer is full (avail_out
- == 0), or after each call of deflate(). If deflate returns Z_OK and with
- zero avail_out, it must be called again after making room in the output
- buffer because there might be more output pending.
-
- Normally the parameter flush is set to Z_NO_FLUSH, which allows deflate to
- decide how much data to accumulate before producing output, in order to
- maximize compression.
-
- If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
- flushed to the output buffer and the output is aligned on a byte boundary, so
- that the decompressor can get all input data available so far. (In
- particular avail_in is zero after the call if enough output space has been
- provided before the call.) Flushing may degrade compression for some
- compression algorithms and so it should be used only when necessary. This
- completes the current deflate block and follows it with an empty stored block
- that is three bits plus filler bits to the next byte, followed by four bytes
- (00 00 ff ff).
-
- If flush is set to Z_PARTIAL_FLUSH, all pending output is flushed to the
- output buffer, but the output is not aligned to a byte boundary. All of the
- input data so far will be available to the decompressor, as for Z_SYNC_FLUSH.
- This completes the current deflate block and follows it with an empty fixed
- codes block that is 10 bits long. This assures that enough bytes are output
- in order for the decompressor to finish the block before the empty fixed code
- block.
-
- If flush is set to Z_BLOCK, a deflate block is completed and emitted, as
- for Z_SYNC_FLUSH, but the output is not aligned on a byte boundary, and up to
- seven bits of the current block are held to be written as the next byte after
- the next deflate block is completed. In this case, the decompressor may not
- be provided enough bits at this point in order to complete decompression of
- the data provided so far to the compressor. It may need to wait for the next
- block to be emitted. This is for advanced applications that need to control
- the emission of deflate blocks.
-
- If flush is set to Z_FULL_FLUSH, all output is flushed as with
- Z_SYNC_FLUSH, and the compression state is reset so that decompression can
- restart from this point if previous compressed data has been damaged or if
- random access is desired. Using Z_FULL_FLUSH too often can seriously degrade
- compression.
-
- If deflate returns with avail_out == 0, this function must be called again
- with the same value of the flush parameter and more output space (updated
- avail_out), until the flush is complete (deflate returns with non-zero
- avail_out). In the case of a Z_FULL_FLUSH or Z_SYNC_FLUSH, make sure that
- avail_out is greater than six to avoid repeated flush markers due to
- avail_out == 0 on return.
-
- If the parameter flush is set to Z_FINISH, pending input is processed,
- pending output is flushed and deflate returns with Z_STREAM_END if there was
- enough output space; if deflate returns with Z_OK, this function must be
- called again with Z_FINISH and more output space (updated avail_out) but no
- more input data, until it returns with Z_STREAM_END or an error. After
- deflate has returned Z_STREAM_END, the only possible operations on the stream
- are deflateReset or deflateEnd.
-
- Z_FINISH can be used immediately after deflateInit if all the compression
- is to be done in a single step. In this case, avail_out must be at least the
- value returned by deflateBound (see below). Then deflate is guaranteed to
- return Z_STREAM_END. If not enough output space is provided, deflate will
- not return Z_STREAM_END, and it must be called again as described above.
-
- deflate() sets strm->adler to the adler32 checksum of all input read
- so far (that is, total_in bytes).
-
- deflate() may update strm->data_type if it can make a good guess about
- the input data type (Z_BINARY or Z_TEXT). In doubt, the data is considered
- binary. This field is only for information purposes and does not affect the
- compression algorithm in any manner.
-
- deflate() returns Z_OK if some progress has been made (more input
- processed or more output produced), Z_STREAM_END if all input has been
- consumed and all output has been produced (only when flush is set to
- Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example
- if next_in or next_out was Z_NULL), Z_BUF_ERROR if no progress is possible
- (for example avail_in or avail_out was zero). Note that Z_BUF_ERROR is not

- - Provide more output starting at next_out and update next_out and avail_out
- accordingly. inflate() provides as much output as possible, until there is
- no more input data or no more space in the output buffer (see below about
- the flush parameter).
-
- Before the call of inflate(), the application should ensure that at least
- one of the actions is possible, by providing more input and/or consuming more
- output, and updating the next_* and avail_* values accordingly. The
- application can consume the uncompressed output when it wants, for example
- when the output buffer is full (avail_out == 0), or after each call of
- inflate(). If inflate returns Z_OK and with zero avail_out, it must be
- called again after making room in the output buffer because there might be
- more output pending.
-
- The flush parameter of inflate() can be Z_NO_FLUSH, Z_SYNC_FLUSH, Z_FINISH,
- Z_BLOCK, or Z_TREES. Z_SYNC_FLUSH requests that inflate() flush as much
- output as possible to the output buffer. Z_BLOCK requests that inflate()
- stop if and when it gets to the next deflate block boundary. When decoding
- the zlib or gzip format, this will cause inflate() to return immediately
- after the header and before the first block. When doing a raw inflate,
- inflate() will go ahead and process the first block, and will return when it
- gets to the end of that block, or when it runs out of data.
-
- The Z_BLOCK option assists in appending to or combining deflate streams.
- Also to assist in this, on return inflate() will set strm->data_type to the
- number of unused bits in the last byte taken from strm->next_in, plus 64 if
- inflate() is currently decoding the last block in the deflate stream, plus
- 128 if inflate() returned immediately after decoding an end-of-block code or
- decoding the complete header up to just before the first byte of the deflate
- stream. The end-of-block will not be indicated until all of the uncompressed
- data from that block has been written to strm->next_out. The number of
- unused bits may in general be greater than seven, except when bit 7 of
- data_type is set, in which case the number of unused bits will be less than
- eight. data_type is set as noted here every time inflate() returns for all
- flush options, and so can be used to determine the amount of currently
- consumed input in bits.
-
- The Z_TREES option behaves as Z_BLOCK does, but it also returns when the
- end of each deflate block header is reached, before any actual data in that
- block is decoded. This allows the caller to determine the length of the
- deflate block header for later use in random access within a deflate block.
- 256 is added to the value of strm->data_type when inflate() returns
- immediately after reaching the end of the deflate block header.
-
- inflate() should normally be called until it returns Z_STREAM_END or an
- error. However if all decompression is to be performed in a single step (a
- single call of inflate), the parameter flush should be set to Z_FINISH. In
- this case all pending input is processed and all pending output is flushed;
- avail_out must be large enough to hold all of the uncompressed data for the
- operation to complete. (The size of the uncompressed data may have been
- saved by the compressor for this purpose.) The use of Z_FINISH is not
- required to perform an inflation in one step. However it may be used to
- inform inflate that a faster approach can be used for the single inflate()
- call. Z_FINISH also informs inflate to not maintain a sliding window if the
- stream completes, which reduces inflate's memory footprint. If the stream
- does not complete, either because not all of the stream is provided or not
- enough output space is provided, then a sliding window will be allocated and
- inflate() can be called again to continue the operation as if Z_NO_FLUSH had
- been used.
-
- In this implementation, inflate() always flushes as much output as
- possible to the output buffer, and always uses the faster approach on the
- first call. So the effects of the flush parameter in this implementation are
- on the return value of inflate() as noted below, when inflate() returns early
- when Z_BLOCK or Z_TREES is used, and when inflate() avoids the allocation of
- memory for a sliding window when Z_FINISH is used.
-
- If a preset dictionary is needed after this call (see inflateSetDictionary
- below), inflate sets strm->adler to the Adler-32 checksum of the dictionary
- chosen by the compressor and returns Z_NEED_DICT; otherwise it sets
- strm->adler to the Adler-32 checksum of all output produced so far (that is,
- total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described
- below. At the end of the stream, inflate() checks that its computed adler32
- checksum is equal to that saved by the compressor and returns Z_STREAM_END
- only if the checksum is correct.
-
- inflate() can decompress and check either zlib-wrapped or gzip-wrapped
- deflate data. The header type is detected automatically, if requested when
- initializing with inflateInit2(). Any information contained in the gzip
- header is not retained, so applications that need that information should
- instead use raw inflate, see inflateInit2() below, or inflateBack() and
- perform their own processing of the gzip header and trailer. When processing
- gzip-wrapped deflate data, strm->adler32 is set to the CRC-32 of the output
- producted so far. The CRC-32 is checked against the gzip trailer.
-
- inflate() returns Z_OK if some progress has been made (more input processed
- or more output produced), Z_STREAM_END if the end of the compressed data has
- been reached and all uncompressed output has been produced, Z_NEED_DICT if a
- preset dictionary is needed at this point, Z_DATA_ERROR if the input data was
- corrupted (input stream not conforming to the zlib format or incorrect check
- value), Z_STREAM_ERROR if the stream structure was inconsistent (for example
- next_in or next_out was Z_NULL), Z_MEM_ERROR if there was not enough memory,
- Z_BUF_ERROR if no progress is possible or if there was not enough room in the
- output buffer when Z_FINISH is used. Note that Z_BUF_ERROR is not fatal, and
- inflate() can be called again with more input and more output space to
- continue decompressing. If Z_DATA_ERROR is returned, the application may
- then call inflateSync() to look for a good compression block if a partial
- recovery of the data is desired.

- int method,
- int windowBits,
- int memLevel,
- int strategy));
-
- This is another version of deflateInit with more compression options. The
- fields next_in, zalloc, zfree and opaque must be initialized before by the
- caller.
-
- The method parameter is the compression method. It must be Z_DEFLATED in
- this version of the library.
-
- The windowBits parameter is the base two logarithm of the window size
- (the size of the history buffer). It should be in the range 8..15 for this
- version of the library. Larger values of this parameter result in better
- compression at the expense of memory usage. The default value is 15 if
- deflateInit is used instead.
-
- windowBits can also be -8..-15 for raw deflate. In this case, -windowBits
- determines the window size. deflate() will then generate raw deflate data
- with no zlib header or trailer, and will not compute an adler32 check value.
-
- windowBits can also be greater than 15 for optional gzip encoding. Add
- 16 to windowBits to write a simple gzip header and trailer around the
- compressed data instead of a zlib wrapper. The gzip header will have no
- file name, no extra data, no comment, no modification time (set to zero), no
- header crc, and the operating system will be set to 255 (unknown). If a
- gzip stream is being written, strm->adler is a crc32 instead of an adler32.
-
- The memLevel parameter specifies how much memory should be allocated
- for the internal compression state. memLevel=1 uses minimum memory but is
- slow and reduces compression ratio; memLevel=9 uses maximum memory for
- optimal speed. The default value is 8. See zconf.h for total memory usage
- as a function of windowBits and memLevel.
-
- The strategy parameter is used to tune the compression algorithm. Use the
- value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
- filter (or predictor), Z_HUFFMAN_ONLY to force Huffman encoding only (no
- string match), or Z_RLE to limit match distances to one (run-length
- encoding). Filtered data consists mostly of small values with a somewhat
- random distribution. In this case, the compression algorithm is tuned to
- compress them better. The effect of Z_FILTERED is to force more Huffman
- coding and less string matching; it is somewhat intermediate between
- Z_DEFAULT_STRATEGY and Z_HUFFMAN_ONLY. Z_RLE is designed to be almost as
- fast as Z_HUFFMAN_ONLY, but give better compression for PNG image data. The
- strategy parameter only affects the compression ratio but not the
- correctness of the compressed output even if it is not set appropriately.
- Z_FIXED prevents the use of dynamic Huffman codes, allowing for a simpler
- decoder for special applications.
-
- deflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was not enough
- memory, Z_STREAM_ERROR if any parameter is invalid (such as an invalid
- method), or Z_VERSION_ERROR if the zlib library version (zlib_version) is

- Initializes the compression dictionary from the given byte sequence

- function must be called either before any call of deflate, or immediately
- after the completion of a deflate block, i.e. after all input has been

- options Z_BLOCK, Z_PARTIAL_FLUSH, Z_SYNC_FLUSH, or Z_FULL_FLUSH. The

-
- The dictionary should consist of strings (byte sequences) that are likely
- to be encountered later in the data to be compressed, with the most commonly
- used strings preferably put towards the end of the dictionary. Using a
- dictionary is most useful when the data to be compressed is short and can be
- predicted with good accuracy; the data can then be compressed better than
- with the default empty dictionary.
-
- Depending on the size of the compression data structures selected by
- deflateInit or deflateInit2, a part of the dictionary may in effect be

- inflateBack() does a raw inflate with a single call using a call-back
- interface for input and output. This is more efficient than inflate() for
- file i/o applications in that it avoids copying between the output and the
- sliding window by simply making the window itself the output buffer. This
- function trusts the application to not change the output buffer passed by
- the output function, at least until inflateBack() returns.
-
- inflateBackInit() must be called first to allocate the internal state
- and to initialize the state with the user-provided window buffer.
- inflateBack() may then be used multiple times to inflate a complete, raw
- deflate stream with each call. inflateBackEnd() is then called to free the
- allocated state.
-
- A raw deflate stream is one with no zlib or gzip header or trailer.
- This routine would normally be used in a utility that reads zip or gzip
- files and writes out uncompressed files. The utility would decode the
- header and process the trailer on its own, hence this routine expects only
- the raw deflate stream to decompress. This is different from the normal
- behavior of inflate(), which expects either a zlib or gzip header and
- trailer around the deflate stream.
-
- inflateBack() uses two subroutines supplied by the caller that are then
- called by inflateBack() for input and output. inflateBack() calls those
- routines until it reads a complete deflate stream and writes out all of the
- uncompressed data, or until it encounters an error. The function's
- parameters and return types are defined above in the in_func and out_func
- typedefs. inflateBack() will call in(in_desc, &buf) which should return the
- number of bytes of provided input, and a pointer to that input in buf. If
- there is no input available, in() must return zero--buf is ignored in that
- case--and inflateBack() will return a buffer error. inflateBack() will call
- out(out_desc, buf, len) to write the uncompressed data buf[0..len-1]. out()
- should return zero on success, or non-zero on failure. If out() returns
- non-zero, inflateBack() will return with an error. Neither in() nor out()
- are permitted to change the contents of the window provided to
- inflateBackInit(), which is also the buffer that out() uses to write from.
- The length written by out() will be at most the window size. Any non-zero
- amount of input may be provided by in().
-
- For convenience, inflateBack() can be provided input on the first call by
- setting strm->next_in and strm->avail_in. If that input is exhausted, then
- in() will be called. Therefore strm->next_in must be initialized before
- calling inflateBack(). If strm->next_in is Z_NULL, then in() will be called
- immediately for input. If strm->next_in is not Z_NULL, then strm->avail_in
- must also be initialized, and then if strm->avail_in is not zero, input will
- initially be taken from strm->next_in[0 .. strm->avail_in - 1].
-
- The in_desc and out_desc parameters of inflateBack() is passed as the
- first parameter of in() and out() respectively when they are called. These
- descriptors can be optionally used to pass any information that the caller-
- supplied in() and out() functions need to do their job.
-
- On return, inflateBack() will set strm->next_in and strm->avail_in to
- pass back any unused input that was provided by the last in() call. The
- return values of inflateBack() can be Z_STREAM_END on success, Z_BUF_ERROR
- if in() or out() returned an error, Z_DATA_ERROR if there was a format error
- in the deflate stream (in which case strm->msg is set to indicate the nature
- of the error), or Z_STREAM_ERROR if the stream was not properly initialized.
- In the case of Z_BUF_ERROR, an input or output error can be distinguished
- using strm->next_in which will be Z_NULL only if in() returned an error. If
- strm->next_in is not Z_NULL, then the Z_BUF_ERROR was due to out() returning
- non-zero. (in() will always be called before out(), so strm->next_in is
- assured to be defined if out() returns non-zero.) Note that inflateBack()

- If something other than a gzip stream is encountered after a gzip stream,
- that remaining trailing garbage is ignored (and no error is returned).
-

- of an incomplete gzip stream. This error is deferred until gzclose(), which

-.TH ZLIB 3 "2 May 2012"
-.SH NAME
-zlib \- compression/decompression library
-.SH SYNOPSIS
-[see
-.I zlib.h
-for full description]
-.SH DESCRIPTION
-The
-.I zlib
-library is a general purpose data compression library.
-The code is thread safe, assuming that the standard library functions
-used are thread safe, such as memory allocation routines.
-It provides in-memory compression and decompression functions,
-including integrity checks of the uncompressed data.
-This version of the library supports only one compression method (deflation)
-but other algorithms may be added later
-with the same stream interface.
-.LP
-Compression can be done in a single step if the buffers are large enough
-or can be done by repeated calls of the compression function.
-In the latter case,
-the application must provide more input and/or consume the output
-(providing more output space) before each call.
-.LP
-The library also supports reading and writing files in
-.IR gzip (1)
-(.gz) format
-with an interface similar to that of stdio.
-.LP
-The library does not install any signal handler.
-The decoder checks the consistency of the compressed data,
-so the library should never crash even in the case of corrupted input.
-.LP
-All functions of the compression library are documented in the file
-.IR zlib.h .
-The distribution source includes examples of use of the library
-in the files
-.I test/example.c
-and
-.IR test/minigzip.c,
-as well as other examples in the
-.IR examples/
-directory.
-.LP
-Changes to this version are documented in the file
-.I ChangeLog
-that accompanies the source.
-.LP
-.I zlib
-is available in Java using the java.util.zip package:
-.IP
-http://java.sun.com/developer/technicalArticles/Programming/compression/
-.LP
-A Perl interface to
-.IR zlib ,
-written by Paul Marquess (pmqs@cpan.org),
-is available at CPAN (Comprehensive Perl Archive Network) sites,

-.LP
-.I zlib
-is built into
-.IR tcl:

-An experimental package to read and write files in .zip format,
-written on top of
-.I zlib
-by Gilles Vollant (info@winimage.com),

+ The 'zlib' compression library provides in-memory compression and
+ decompression functions, including integrity checks of the uncompressed
+ data. This version of the library supports only one compression method
+ (deflation) but other algorithms will be added later and will have the same
+ stream interface.
+
+ Compression can be done in a single step if the buffers are large
+ enough (for example if an input file is mmap'ed), or can be done by
+ repeated calls of the compression function. In the latter case, the
+ application must provide more input and/or consume the output
+ (providing more output space) before each call.
+
+ The compressed data format used by default by the in-memory functions is
+ the zlib format, which is a zlib wrapper documented in RFC 1950, wrapped
+ around a deflate stream, which is itself documented in RFC 1951.
+
+ The library also supports reading and writing files in gzip (.gz) format
+ with an interface similar to that of stdio using the functions that start
+ with "gz". The gzip format is different from the zlib format. gzip is a
+ gzip wrapper, documented in RFC 1952, wrapped around a deflate stream.
+
+ This library can optionally read and write gzip streams in memory as well.
+
+ The zlib format was designed to be compact and fast for use in memory
+ and on communications channels. The gzip format was designed for single-
+ file compression on file systems, has a larger header than zlib to maintain
+ directory information, and uses a different, slower check method than zlib.
+
+ The library does not install any signal handler. The decoder checks
+ the consistency of the compressed data, so the library should never
+ crash even in case of corrupted input.

+ deflate compresses as much data as possible, and stops when the input
+ buffer becomes empty or the output buffer becomes full. It may introduce some
+ output latency (reading input without producing any output) except when
+ forced to flush.
+
+ The detailed semantics are as follows. deflate performs one or both of the
+ following actions:
+
+ - Compress more input starting at next_in and update next_in and avail_in
+ accordingly. If not all input can be processed (because there is not
+ enough room in the output buffer), next_in and avail_in are updated and
+ processing will resume at this point for the next call of deflate().
+
+ - Provide more output starting at next_out and update next_out and avail_out
+ accordingly. This action is forced if the parameter flush is non zero.
+ Forcing flush frequently degrades the compression ratio, so this parameter
+ should be set only when necessary (in interactive applications).
+ Some output may be provided even if flush is not set.
+
+ Before the call of deflate(), the application should ensure that at least
+ one of the actions is possible, by providing more input and/or consuming
+ more output, and updating avail_in or avail_out accordingly; avail_out
+ should never be zero before the call. The application can consume the
+ compressed output when it wants, for example when the output buffer is full
+ (avail_out == 0), or after each call of deflate(). If deflate returns Z_OK
+ and with zero avail_out, it must be called again after making room in the
+ output buffer because there might be more output pending.
+
+ Normally the parameter flush is set to Z_NO_FLUSH, which allows deflate to
+ decide how much data to accumualte before producing output, in order to
+ maximize compression.
+
+ If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
+ flushed to the output buffer and the output is aligned on a byte boundary, so
+ that the decompressor can get all input data available so far. (In particular
+ avail_in is zero after the call if enough output space has been provided
+ before the call.) Flushing may degrade compression for some compression
+ algorithms and so it should be used only when necessary.
+
+ If flush is set to Z_FULL_FLUSH, all output is flushed as with
+ Z_SYNC_FLUSH, and the compression state is reset so that decompression can
+ restart from this point if previous compressed data has been damaged or if
+ random access is desired. Using Z_FULL_FLUSH too often can seriously degrade
+ compression.
+
+ If deflate returns with avail_out == 0, this function must be called again
+ with the same value of the flush parameter and more output space (updated
+ avail_out), until the flush is complete (deflate returns with non-zero
+ avail_out). In the case of a Z_FULL_FLUSH or Z_SYNC_FLUSH, make sure that
+ avail_out is greater than six to avoid repeated flush markers due to
+ avail_out == 0 on return.
+
+ If the parameter flush is set to Z_FINISH, pending input is processed,
+ pending output is flushed and deflate returns with Z_STREAM_END if there
+ was enough output space; if deflate returns with Z_OK, this function must be
+ called again with Z_FINISH and more output space (updated avail_out) but no
+ more input data, until it returns with Z_STREAM_END or an error. After
+ deflate has returned Z_STREAM_END, the only possible operations on the
+ stream are deflateReset or deflateEnd.
+
+ Z_FINISH can be used immediately after deflateInit if all the compression
+ is to be done in a single step. In this case, avail_out must be at least
+ the value returned by deflateBound (see below). If deflate does not return
+ Z_STREAM_END, then it must be called again as described above.
+
+ deflate() sets strm->adler to the adler32 checksum of all input read
+ so far (that is, total_in bytes).
+
+ deflate() may update strm->data_type if it can make a good guess about
+ the input data type (Z_BINARY or Z_TEXT). In doubt, the data is considered
+ binary. This field is only for information purposes and does not affect
+ the compression algorithm in any manner.
+
+ deflate() returns Z_OK if some progress has been made (more input
+ processed or more output produced), Z_STREAM_END if all input has been
+ consumed and all output has been produced (only when flush is set to
+ Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example
+ if next_in or next_out was NULL), Z_BUF_ERROR if no progress is possible
+ (for example avail_in or avail_out was zero). Note that Z_BUF_ERROR is not

+ inflate decompresses as much data as possible, and stops when the input
+ buffer becomes empty or the output buffer becomes full. It may introduce
+ some output latency (reading input without producing any output) except when
+ forced to flush.
+
+ The detailed semantics are as follows. inflate performs one or both of the
+ following actions:
+
+ - Decompress more input starting at next_in and update next_in and avail_in
+ accordingly. If not all input can be processed (because there is not
+ enough room in the output buffer), next_in is updated and processing
+ will resume at this point for the next call of inflate().
+
+ - Provide more output starting at next_out and update next_out and avail_out
+ accordingly. inflate() provides as much output as possible, until there
+ is no more input data or no more space in the output buffer (see below
+ about the flush parameter).
+
+ Before the call of inflate(), the application should ensure that at least
+ one of the actions is possible, by providing more input and/or consuming
+ more output, and updating the next_* and avail_* values accordingly.
+ The application can consume the uncompressed output when it wants, for
+ example when the output buffer is full (avail_out == 0), or after each
+ call of inflate(). If inflate returns Z_OK and with zero avail_out, it
+ must be called again after making room in the output buffer because there
+ might be more output pending.
+
+ The flush parameter of inflate() can be Z_NO_FLUSH, Z_SYNC_FLUSH,
+ Z_FINISH, or Z_BLOCK. Z_SYNC_FLUSH requests that inflate() flush as much
+ output as possible to the output buffer. Z_BLOCK requests that inflate() stop
+ if and when it gets to the next deflate block boundary. When decoding the
+ zlib or gzip format, this will cause inflate() to return immediately after
+ the header and before the first block. When doing a raw inflate, inflate()
+ will go ahead and process the first block, and will return when it gets to
+ the end of that block, or when it runs out of data.
+
+ The Z_BLOCK option assists in appending to or combining deflate streams.
+ Also to assist in this, on return inflate() will set strm->data_type to the
+ number of unused bits in the last byte taken from strm->next_in, plus 64
+ if inflate() is currently decoding the last block in the deflate stream,
+ plus 128 if inflate() returned immediately after decoding an end-of-block
+ code or decoding the complete header up to just before the first byte of the
+ deflate stream. The end-of-block will not be indicated until all of the
+ uncompressed data from that block has been written to strm->next_out. The
+ number of unused bits may in general be greater than seven, except when
+ bit 7 of data_type is set, in which case the number of unused bits will be
+ less than eight.
+
+ inflate() should normally be called until it returns Z_STREAM_END or an
+ error. However if all decompression is to be performed in a single step
+ (a single call of inflate), the parameter flush should be set to
+ Z_FINISH. In this case all pending input is processed and all pending
+ output is flushed; avail_out must be large enough to hold all the
+ uncompressed data. (The size of the uncompressed data may have been saved
+ by the compressor for this purpose.) The next operation on this stream must
+ be inflateEnd to deallocate the decompression state. The use of Z_FINISH
+ is never required, but can be used to inform inflate that a faster approach
+ may be used for the single inflate() call.
+
+ In this implementation, inflate() always flushes as much output as
+ possible to the output buffer, and always uses the faster approach on the
+ first call. So the only effect of the flush parameter in this implementation
+ is on the return value of inflate(), as noted below, or when it returns early
+ because Z_BLOCK is used.
+
+ If a preset dictionary is needed after this call (see inflateSetDictionary
+ below), inflate sets strm->adler to the adler32 checksum of the dictionary
+ chosen by the compressor and returns Z_NEED_DICT; otherwise it sets
+ strm->adler to the adler32 checksum of all output produced so far (that is,
+ total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described
+ below. At the end of the stream, inflate() checks that its computed adler32
+ checksum is equal to that saved by the compressor and returns Z_STREAM_END
+ only if the checksum is correct.
+
+ inflate() will decompress and check either zlib-wrapped or gzip-wrapped
+ deflate data. The header type is detected automatically. Any information
+ contained in the gzip header is not retained, so applications that need that
+ information should instead use raw inflate, see inflateInit2() below, or
+ inflateBack() and perform their own processing of the gzip header and
+ trailer.
+
+ inflate() returns Z_OK if some progress has been made (more input processed
+ or more output produced), Z_STREAM_END if the end of the compressed data has
+ been reached and all uncompressed output has been produced, Z_NEED_DICT if a
+ preset dictionary is needed at this point, Z_DATA_ERROR if the input data was
+ corrupted (input stream not conforming to the zlib format or incorrect check
+ value), Z_STREAM_ERROR if the stream structure was inconsistent (for example
+ if next_in or next_out was NULL), Z_MEM_ERROR if there was not enough memory,
+ Z_BUF_ERROR if no progress is possible or if there was not enough room in the
+ output buffer when Z_FINISH is used. Note that Z_BUF_ERROR is not fatal, and
+ inflate() can be called again with more input and more output space to
+ continue decompressing. If Z_DATA_ERROR is returned, the application may then
+ call inflateSync() to look for a good compression block if a partial recovery

+
+ This is another version of deflateInit with more compression options. The
+ fields next_in, zalloc, zfree and opaque must be initialized before by
+ the caller.
+
+ The method parameter is the compression method. It must be Z_DEFLATED in
+ this version of the library.
+
+ The windowBits parameter is the base two logarithm of the window size
+ (the size of the history buffer). It should be in the range 8..15 for this
+ version of the library. Larger values of this parameter result in better
+ compression at the expense of memory usage. The default value is 15 if
+ deflateInit is used instead.
+
+ windowBits can also be -8..-15 for raw deflate. In this case, -windowBits
+ determines the window size. deflate() will then generate raw deflate data
+ with no zlib header or trailer, and will not compute an adler32 check value.
+
+ windowBits can also be greater than 15 for optional gzip encoding. Add
+ 16 to windowBits to write a simple gzip header and trailer around the
+ compressed data instead of a zlib wrapper. The gzip header will have no
+ file name, no extra data, no comment, no modification time (set to zero),
+ no header crc, and the operating system will be set to 255 (unknown). If a
+ gzip stream is being written, strm->adler is a crc32 instead of an adler32.
+
+ The memLevel parameter specifies how much memory should be allocated
+ for the internal compression state. memLevel=1 uses minimum memory but
+ is slow and reduces compression ratio; memLevel=9 uses maximum memory
+ for optimal speed. The default value is 8. See zconf.h for total memory
+ usage as a function of windowBits and memLevel.
+
+ The strategy parameter is used to tune the compression algorithm. Use the
+ value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
+ filter (or predictor), Z_HUFFMAN_ONLY to force Huffman encoding only (no
+ string match), or Z_RLE to limit match distances to one (run-length
+ encoding). Filtered data consists mostly of small values with a somewhat

+ function trusts the application to not change the output buffer passed by
+ the output function, at least until inflateBack() returns.
+
+ inflateBackInit() must be called first to allocate the internal state
+ and to initialize the state with the user-provided window buffer.
+ inflateBack() may then be used multiple times to inflate a complete, raw
+ deflate stream with each call. inflateBackEnd() is then called to free
+ the allocated state.
+
+ A raw deflate stream is one with no zlib or gzip header or trailer.
+ This routine would normally be used in a utility that reads zip or gzip
+ files and writes out uncompressed files. The utility would decode the

+ only the raw deflate stream to decompress. This is different from the
+ normal behavior of inflate(), which expects either a zlib or gzip header and
+ trailer around the deflate stream.
+
+ inflateBack() uses two subroutines supplied by the caller that are then
+ called by inflateBack() for input and output. inflateBack() calls those
+ routines until it reads a complete deflate stream and writes out all of the
+ uncompressed data, or until it encounters an error. The function's
+ parameters and return types are defined above in the in_func and out_func
+ typedefs. inflateBack() will call in(in_desc, &buf) which should return the
+ number of bytes of provided input, and a pointer to that input in buf. If
+ there is no input available, in() must return zero--buf is ignored in that
+ case--and inflateBack() will return a buffer error. inflateBack() will call
+ out(out_desc, buf, len) to write the uncompressed data buf[0..len-1]. out()
+ should return zero on success, or non-zero on failure. If out() returns
+ non-zero, inflateBack() will return with an error. Neither in() nor out()
+ are permitted to change the contents of the window provided to
+ inflateBackInit(), which is also the buffer that out() uses to write from.
+ The length written by out() will be at most the window size. Any non-zero
+ amount of input may be provided by in().
+
+ For convenience, inflateBack() can be provided input on the first call by
+ setting strm->next_in and strm->avail_in. If that input is exhausted, then
+ in() will be called. Therefore strm->next_in must be initialized before
+ calling inflateBack(). If strm->next_in is Z_NULL, then in() will be called
+ immediately for input. If strm->next_in is not Z_NULL, then strm->avail_in
+ must also be initialized, and then if strm->avail_in is not zero, input will
+ initially be taken from strm->next_in[0 .. strm->avail_in - 1].
+
+ The in_desc and out_desc parameters of inflateBack() is passed as the
+ first parameter of in() and out() respectively when they are called. These
+ descriptors can be optionally used to pass any information that the caller-
+ supplied in() and out() functions need to do their job.
+
+ On return, inflateBack() will set strm->next_in and strm->avail_in to

+ error in the deflate stream (in which case strm->msg is set to indicate the

+ an error. If strm->next is not Z_NULL, then the Z_BUF_ERROR was due to
+ out() returning non-zero. (in() will always be called before out(), so
