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.
