@findex fseeko

POSIX specification: @url{http://www.opengroup.org/susv3xsh/fseeko.html}

Gnulib module: fseeko

Portability problems fixed by Gnulib:

@itemize

@item
|
|
This function is missing on some platforms:
|
|
OSF/1 4.0, Solaris 2.5.1, mingw.
|
|
@item
|
|
The declaration of @code{fseeko} in @code{<stdio.h>} is not enabled by default
|
|
on some platforms: glibc 2.3.6.
|
|
@item
|
|
This function fails on seekable stdin, stdout, and stderr: cygwin <= 1.5.24.

Portability problems not fixed by Gnulib:
|
|
@itemize
|
|
@item
|
|
On platforms where @code{off_t} is a 32-bit type, @code{fseeko} does not work
|
|
correctly with files larger than 2 GB. The fix is to use the
|
|
@code{AC_SYS_LARGEFILE} macro.
|
|
@item
|
|
On platforms where @code{off_t} is a 64-bit type, but @code{fseeko} is
|
|
not present, stream operations on files larger than 2 GB silently do
|
|
the wrong thing. This affects BSD/OS, which is mostly obsolete.
