fcloseall3
Close all open streams
Usage
#define _GNU_SOURCE /* See feature_test_macros(7) */ #include <stdio.h>
int fcloseall(void);
Library
Standard C library (libc, -lc)
Overview
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

| fcloseall() | Thread safety | MT-Unsafe race:streams |
