FCLOSEALL(3C) Standard C Library Functions FCLOSEALL(3C)

NAME


fcloseall - close all standard I/O streams

SYNOPSIS


#include <stdio.h>

int
fcloseall(void);

DESCRIPTION


The fcloseall() function closes all open standard I/O streams. The
equivalent of fflush(3C) is called on each stream before closing, thus any
buffered or pending input is discarded while any buffered or pending output
is written out to the underlying file. This includes the standard streams,
stdin, stdout, and stderr.

RETURN VALUES


Currently, the function fcloseall() always returns 0. Note, portable
applications should always check the return value.

INTERFACE STABILITY


Committed.

MT-LEVEL
Mt-Safe.
