@node fseek @section @code{fseek} @findex fseek POSIX specification:@* @url{http://www.opengroup.org/onlinepubs/9699919799/functions/fseek.html} Gnulib module: 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 larger than 2 GB, even when the @code{AC_SYS_LARGEFILE} macro is used. The fix is to use @code{fseeko} instead. @end itemize
