5 POSIX specification: @url{http://www.opengroup.org/onlinepubs/9699919799/functions/fseeko.html}
9 Portability problems fixed by Gnulib:
12 This function is missing on some platforms:
13 IRIX 5.3, OSF/1 4.0, Solaris 2.5.1, mingw.
15 The declaration of @code{fseeko} in @code{<stdio.h>} is not enabled by default
16 on some platforms: glibc 2.3.6.
18 This function fails on seekable stdin, stdout, and stderr: cygwin <= 1.5.24.
21 Portability problems not fixed by Gnulib:
24 On platforms where @code{off_t} is a 32-bit type, @code{fseeko} does not work
25 correctly with files larger than 2 GB. The fix is to use the
26 @code{AC_SYS_LARGEFILE} macro.
28 On platforms where @code{off_t} is a 64-bit type, but @code{fseeko} is
29 not present, stream operations on files larger than 2 GB silently do
30 the wrong thing. This affects BSD/OS, which is mostly obsolete.
