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.

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.
