Given a buffer EVENT_LIMIT bytes long, take the variables present in this object and convert them to a binary form.
It can be assumed that this function will only be called when the Event is about to be dispatched, and so the inhibited mask of the current Thread is available to be changed to what the event handler requires. This change will be undone when the handler completes.
- Parameters
-
pBuffer The buffer to serialize to.
- Returns
- The number of bytes serialized.
Implements Event.
