@node fclose
@section @code{fclose}
@findex fclose
POSIX specification:@* @url{https://pubs.opengroup.org/onlinepubs/9699919799/functions/fclose.html}
Gnulib module: fclose
Portability problems fixed by Gnulib:
@itemize
@item
On some platforms, this function fails to set the file position of a
seekable input stream to the byte after the last one actually read:
glibc 2.34, FreeBSD, AIX 7.2.
@item
This function crashes if the stream's file descriptor has already been
closed on some platforms:
MSVC 14.
@item
On Windows platforms (excluding Cygwin), @code{socket} and @code{accept}
followed by @code{fdopen} do not return streams that can be closed by
@code{fclose}.
@end itemize
Portability problems not fixed by Gnulib:
@itemize
@item
On Windows platforms (excluding Cygwin), this function does not set @code{errno}
upon failure.
