@node fseek
@subsection @code{fseek}
@findex fseek

POSIX specification:@* @url{https://pubs.opengroup.org/onlinepubs/9799919799/functions/fseek.html}

Gnulib module: fseek
@mindex fseek

Portability problems fixed by Gnulib:
@itemize
@item
This function mistakenly succeeds on pipes on some platforms:
mingw, MSVC 14.
@end itemize

Portability problems not fixed by Gnulib:
@itemize
@item
On Windows platforms (excluding Cygwin), this function does not set @code{errno}
upon failure.
@item
On platforms where @code{long} is a 32-bit type, @code{fseek} does not work
correctly with files 2 GiB and larger, even when the @code{AC_SYS_LARGEFILE}
macro is used.  The fix is to use @code{fseeko} instead.
@end itemize
