FCLOSEALL(3)		   Linux Programmer's Manual		  FCLOSEALL(3)

NAME
       fcloseall - close all open streams

SYNOPSIS
       #define _GNU_SOURCE	   /* See feature_test_macros(7) */
       #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.

ATTRIBUTES
   Multithreading (see pthreads(7))
       The fcloseall() function does not  lock	the  streams,  so  it  is  not
       thread-safe.

CONFORMING TO
       This function is a GNU extension.

SEE ALSO
       close(2), fclose(3), fflush(3), fopen(3), setbuf(3)
