NAME
       fcloseall - close all open streams

SYNOPSIS
       #define _GNU_SOURCE
       #include <stdio.h>

       int fcloseall(void);

DESCRIPTION
       The  fcloseall()  function  closes all of the calling process's open streams.  Buffered output for each stream is written
       before it is closed (as for fflush(3)); buffered input is discarded.

       The standard streams, stdin, stdout, and stderr are also closed.

RETURN VALUE
       This function returns 0 if all files were successfully closed; on error, EOF is returned.

CONFORMING TO
       This function is a GNU extension.
