/*** DeclareEvent - post the ocurrance of an event, and pass message

* Called by the various pieces of code that actualy detect event ocurrance,

* event - Event Type.
* pargs - Pointer to any args to be passed to the handling routine
*
* Returns - TRUE if the event has been consumed, and should be further
* ignored by the caller. Else FALSE.
