NAME

fcloseall − close all open streams

SYNOPSIS

#define _GNU_SOURCE /bin /boot /dead.letter /dev /etc /home /initrd /lib /lib64 /lost+found /media /mnt /opt /proc /release-notes.html /release-notes.txt /root /run /sbin /srv /sys /tmp /usr /var See feature_test_macros(7) bodies/ usr/
#include

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

For an explanation of the terms used in this section, see attributes(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)
