FCLOSEALL(3)              Linux Programmer's Manual             FCLOSEALL(3)

NAME         top

       fcloseall - close all open streams

SYNOPSIS         top

       #define _GNU_SOURCE         /* See feature_test_macros(7) */
       #include <stdio.h>

       int fcloseall(void);

DESCRIPTION         top

       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         top

       This function returns 0 if all files were successfully closed; on
       error, EOF is returned.

ATTRIBUTES         top

       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         top

       This function is a GNU extension.
