It depends upon the parameters you're trying to feed to the wait3() call.
If you're just trying to do a WNOHANG-style non-blocking wait, try something
along the lines of (PSEUDO-C Code Follows):

	alarm(1);		/* set alarm time for around 1 second */
	pid = wait(&status);	/* blocking wait(2) */
	alarm(0);		/* reset alarm */

If the wait succeeds - no problem.  If it doesn't, it will be awakened by
the alarm call.
