fclose (GNU Gnulib)

Gnulib module: fclose

Portability problems fixed by Gnulib:

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.
This function crashes if the stream’s file descriptor has already been closed on some platforms: MSVC 14.
On Windows platforms (excluding Cygwin), socket and accept followed by fdopen do not return streams that can be closed by fclose.

Portability problems not fixed by Gnulib:

On Windows platforms (excluding Cygwin), this function does not set errno upon failure.
