+** Source: test4.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 trying to open an event with a name that is
+** already taken by a non-event object.
