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.
