FCLOSEALL(3)                        Linux Programmer's Manual                        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 out‐
       put 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.

ATTRIBUTES
   Multithreading (see pthreads(7))
       The fcloseall() function does not lock the streams, so it is not thread-safe.

CONFORMING TO
       This function is a GNU extension.

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