fcloseall(3) | Library Functions Manual | fcloseall(3) |
NAME¶
fcloseall - close all open streams
LIBRARY¶
Standard C library (libc, -lc)
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¶
For an explanation of the terms used in this section, see attributes(7).
Interface | Attribute | Value |
fcloseall () | Thread safety | MT-Unsafe race:streams |
