| |
| Currently, we only guarantee that I32 is *at least* 32 bits. |
| Specifically, if int is 64 bits, then so is I32. (This is the case |
| for the Cray.) This has the advantage of meshing nicely with |
| standard library calls (where we pass an I32 and the library is |
| expecting an int), but the disadvantage that an I32 is not 32 bits. |
| Andy Dougherty August 1996 |
| |
| There is no guarantee that there is *any* integral type with |
| exactly 32 bits. It is perfectly legal for a system to have |
| sizeof(short) == sizeof(int) == sizeof(long) == 8. |
| |
| Similarly, there is no guarantee that I16 and U16 have exactly 16 |
| bits. |
| |
| For dealing with issues that may arise from various 32/64-bit |
| systems, we will ask Configure to check out |
| |
| SHORTSIZE == sizeof(short) |
| INTSIZE == sizeof(int) |
| LONGSIZE == sizeof(long) |
| LONGLONGSIZE == sizeof(long long) (if HAS_LONG_LONG) |

| =head1 Character classes |
| There are three variants for all the functions in this section. The base ones |
| operate using the character set of the platform Perl is running on. The ones |
| with an C<_A> suffix operate on the ASCII character set, and the ones with an |
| C<_L1> suffix operate on the full Latin1 character set. All are unaffected by |
| locale and by C<use bytes>. |
| |
| For ASCII platforms, the base function with no suffix and the one with the |
| C<_A> suffix are identical. The function with the C<_L1> suffix imposes the |
| Latin-1 character set onto the platform. That is, the code points that are |
| ASCII are unaffected, since ASCII is a subset of Latin-1. But the non-ASCII |
| code points are treated as if they are Latin-1 characters. For example, |
| C<isSPACE_L1()> will return true when called with the code point 0xA0, which is |
| the Latin-1 NO-BREAK SPACE. |
| |
| For EBCDIC platforms, the base function with no suffix and the one with the |
| C<_L1> suffix should be identical, since, as of this writing, the EBCDIC code |
| pages that Perl knows about all are equivalent to Latin-1. The function that |
| ends in an C<_A> suffix will not return true unless the specified character also |
| has an ASCII equivalent. |
| |
| =for apidoc Am|bool|isALPHA|char ch |

| C<isALPHA_A> and C<isALPHA_L1>. |
| |
| =for apidoc Am|bool|isASCII|char ch |
| Returns a boolean indicating whether the specified character is one of the 128 |
| characters in the ASCII character set. On non-ASCII platforms, it is if this |
| character corresponds to an ASCII character. Variants C<isASCII_A()> and |
| C<isASCII_L1()> are identical to C<isASCII()>. |
| |
| =for apidoc Am|bool|isDIGIT|char ch |
| Returns a boolean indicating whether the specified character is a |

| Variants C<isDIGIT_A> and C<isDIGIT_L1> are identical to C<isDIGIT>. |
| |
| =for apidoc Am|bool|isLOWER|char ch |
| Returns a boolean indicating whether the specified character is a |

| C<isLOWER_A> and C<isLOWER_L1>. |
| |
| =for apidoc Am|bool|isOCTAL|char ch |
| Returns a boolean indicating whether the specified character is an |

| Variants C<isOCTAL_A> and C<isOCTAL_L1> are identical to C<isOCTAL>. |
| |
| =for apidoc Am|bool|isSPACE|char ch |
| Returns a boolean indicating whether the specified character is a |
| whitespace character in the platform's native character set. This is the same |
| as what C<\s> matches in a regular expression. |
| See the L<top of this section|/Character classes> for an explanation of variants |
| C<isSPACE_A> and C<isSPACE_L1>. |
| |

| Returns a boolean indicating whether the specified character is an |
| uppercase character in the platform's native character set. |
| See the L<top of this section|/Character classes> for an explanation of variants |
| C<isUPPER_A> and C<isUPPER_L1>. |

| Returns a boolean indicating whether the specified character is a |

| Converts the specified character to uppercase in the platform's native |

| Converts the specified character to lowercase in the platform's native |

| |
| =for apidoc Am|void|Newx|void* ptr|int nitems|type |
| The XSUB-writer's interface to the C C<malloc> function. |
| |
| In 5.9.3, Newx() and friends replace the older New() API, and drops |
| the first parameter, I<x>, a debug aid which allowed callers to identify |
| themselves. This aid has been superseded by a new build option, |
| PERL_MEM_LOG (see L<perlhacktips/PERL_MEM_LOG>). The older API is still |
| there for use in XS modules supporting older perls. |
| |
| =for apidoc Am|void|Newxc|void* ptr|int nitems|type|cast |
| The XSUB-writer's interface to the C C<malloc> function, with |
| cast. See also C<Newx>. |
| |
| =for apidoc Am|void|Newxz|void* ptr|int nitems|type |
| The XSUB-writer's interface to the C C<malloc> function. The allocated |
| memory is zeroed with C<memzero>. See also C<Newx>. |
| |

| The XSUB-writer's interface to the C C<realloc> function. |
| |
| =for apidoc Am|void|Renewc|void* ptr|int nitems|type|cast |
| The XSUB-writer's interface to the C C<realloc> function, with |

| The XSUB-writer's interface to the C C<free> function. |
| |
| =for apidoc Am|void|Move|void* src|void* dest|int nitems|type |
| The XSUB-writer's interface to the C C<memmove> function. The C<src> is the |
| source, C<dest> is the destination, C<nitems> is the number of items, and C<type> is |
| the type. Can do overlapping moves. See also C<Copy>. |
| |
| =for apidoc Am|void *|MoveD|void* src|void* dest|int nitems|type |
| Like C<Move> but returns dest. Useful for encouraging compilers to tail-call |
| optimise. |
| |
| =for apidoc Am|void|Copy|void* src|void* dest|int nitems|type |
| The XSUB-writer's interface to the C C<memcpy> function. The C<src> is the |
| source, C<dest> is the destination, C<nitems> is the number of items, and C<type> is |
| the type. May fail on overlapping copies. See also C<Move>. |
| |
| =for apidoc Am|void *|CopyD|void* src|void* dest|int nitems|type |
| |
| Like C<Copy> but returns dest. Useful for encouraging compilers to tail-call |
| optimise. |
| |
| =for apidoc Am|void|Zero|void* dest|int nitems|type |
| |
| The XSUB-writer's interface to the C C<memzero> function. The C<dest> is the |
| destination, C<nitems> is the number of items, and C<type> is the type. |
| |
| =for apidoc Am|void *|ZeroD|void* dest|int nitems|type |
| |
| Like C<Zero> but returns dest. Useful for encouraging compilers to tail-call |
| optimise. |
| |
| =for apidoc Am|void|StructCopy|type src|type dest|type |
| This is an architecture-independent macro to copy one structure to another. |
| |
| =for apidoc Am|void|PoisonWith|void* dest|int nitems|type|U8 byte |
| |
| Fill up memory with a byte pattern (a byte repeated over and over |
| again) that hopefully catches attempts to access uninitialized memory. |
| |
| =for apidoc Am|void|PoisonNew|void* dest|int nitems|type |
| |
| PoisonWith(0xAB) for catching access to allocated but uninitialized memory. |
