** Source: test5.c
**
** Purpose: Positive test for OpenEventW.
**
** Dependencies: PAL_Initialize
**               PAL_Terminate
**               CreateEvent
**               CloseHandle
**               WaitForSingleObject
**
** Purpose:
**
** Test to ensure proper operation of the OpenEventW()
** API by creating a new named event with CreateEventA()
** and verifying that it can be opened with OpenEventW().
** It should be possible to use the event handles
** interchangeably, we test by setting the event with the
** original handle and waiting on it with the new one,
** then resetting it with the new one and waiting
** on it with the original one.
