Passing data using SetEvent on Windows CE

Martin in the office came across this one, normally SetEvent is used to signal between two threads or even processes that something has happened, a very light weight message queue shall we say, the major limitation is that you can't pass any parameters or data, so you end up having multiple events or storing the parameter information in the registry etc..but using this API you can associate a DWORD of information against an event that is signalled, pretty handy for simple signalling information between drivers and applications...

BOOL SetEventData(   HANDLE hEvent,   DWORD dwData );
