fcloseall
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
For an explanation of the terms used in this section, see attributes(7).
+------------+---------------+------------------------+
|Interface | Attribute | Value |
+------------+---------------+------------------------+
|fcloseall() | Thread safety | MT-Unsafe race:streams |
+------------+---------------+------------------------+
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)
