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

Thread safety
MT-Unsafe race:streams
The fcloseall() function
does not lock the streams, so it is not thread-safe.
