NAME

fcloseall - close all open streams

LIBRARY

Standard C library ( libc , -lc )

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).

The fcloseall () function does not lock the streams, so it is not thread-safe.

STANDARDS

GNU.
