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.

CONFORMING TO         top

       This function is a GNU extension.
