RTCE_BUDDY events have an IRTCBuddyEvent interface. This type of event is fired when the presence state of a Buddy changes.
When the application's implementation of the IRTCEventNotification::Event method indicates an RTC_EVENT of type RTCE_BUDDY, the method's pEvent parameter is an IDispatch pointer for the IRTCBuddyEvent interface. The methods of this interface can be used to retrieve information concerning the change in the presence state of the Buddy.
