** Source: test3.c (DuplicateHandle)
**
** Purpose: Tests the PAL implementation of the DuplicateHandle function.
** This will test duplication of an OpenEvent handle. Test an
** event in a signaled state to wait, and then set the duplicate
** to nonsignaled state and perform the wait again. The wait on
** the event should fail. Test the duplication of closed and NULL
** events, these should fail.
