I can't fathom out how to use CMultiLock.

Anyone know of a good example?

I can find examples that don't work but I would like to study an
example that does work.


OK, I just wrote this example, but you can tell me if you think it won't work:
     CEvent evtThread1, evtThread2, evtThread3;
    // assume these events have been created and have some meaning somewhere

     CSyncObject * apEvents[] = { &evtThread1, &evtThread2, &evtThread3 };
     CMultiLock lockmany( apEvents, _countof(apEvents), FALSE );

     DWORD dwResult = lockmany.Lock( 5000, FALSE );
     switch ( dwResult )
     case WAIT_OBJECT_0:
     case WAIT_OBJECT_0+1:
     case WAIT_OBJECT_0+2:
         DWORD dwEvt = dwResult - WAIT_OBJECT_0;
         // do something in response to the event apEvents[dwEvt];
     case WAIT_TIMEOUT:
         // Do something if timeout expired
         // Do something if wait abandoned
