| Gnulib module: ftell |
| |
| Portability problems fixed by Gnulib: |
| @itemize |
| @item |
| This function mistakenly succeeds on pipes on some platforms: |
| mingw, MSVC 14. |
| @item |
| This function produces incorrect results after @code{putc} that followed a |
| @code{getc} call that reached EOF on some platforms: |
| Solaris 11 2010-11. |
| @end itemize |
| |
| Portability problems not fixed by Gnulib: |
| @itemize |
| @item |
| This function produces incorrect results immediately after @code{fseek} on some |
| platforms: |
| HP-UX 11. |
| @item |
| @code{fflush}, @code{ftell}, @code{ftello}, @code{fgetpos} behave incorrectly |
| on input streams that are opened in @code{O_TEXT} mode and whose contents |
| contains Unix line terminators (LF), on some platforms: mingw, MSVC 14. |
| @item |
| On platforms where @code{long} is a 32-bit type, @code{ftell} does not work |
| correctly with files larger than 2 GB, even when the @code{AC_SYS_LARGEFILE} |
| macro is used. The fix is to use @code{ftello} instead. |
