#define _GNU_SOURCE /* See feature_test_macros(7) */ #include <stdio.h> int fcloseall(void);
LIBRARY
Standard C library (libc, -lc)
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.

Thread safety
MT-Unsafe race:streams

is not thread-safe.
