5 POSIX specification:@* @url{http://www.opengroup.org/onlinepubs/9699919799/functions/ftell.html}
9 Portability problems fixed by Gnulib:
12 This function mistakenly succeeds on pipes on some platforms:
15 This function produces incorrect results after @code{putc} that followed a
16 @code{getc} call that reached EOF on some platforms:
20 Portability problems not fixed by Gnulib:
23 This function produces incorrect results immediately after @code{fseek} on some
27 @code{fflush}, @code{ftell}, @code{ftello}, @code{fgetpos} behave incorrectly
28 on input streams that are opened in @code{O_TEXT} mode and whose contents
29 contains Unix line terminators (LF), on some platforms: mingw, MSVC 9.
31 On platforms where @code{long} is a 32-bit type, @code{ftell} does not work
32 correctly with files larger than 2 GB, even when the @code{AC_SYS_LARGEFILE}
33 macro is used. The fix is to use @code{ftello} instead.
