** Source: test2.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 and verifying that
** it can be used interchangeably 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.
