fcloseall(3)



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.
