NAME

       fcloseall - close all open streams

SYNOPSIS

       #define _GNU_SOURCE

       #include <stdio.h>

       int fcloseall(void);

DESCRIPTION

       The  fcloseall  function  dissociates  all  open streams from its underlying file or set of functions.  Any buffered output data is written
       first, using fflush(3).	Note that the standard streams (stdin, stdout and stderr) are also closed.

RETURN VALUE

       This function always returns 0.

SEE ALSO

       fclose(3), close(2), fflush(3), fopen(3), setbuf(3)

CONFORMING TO

       The fcloseall function is a GNU extension.

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.

       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.
