The IRTCPresenceDataEvent interface contains methods for retrieving presence data.
When the application's implementation of the IRTCEventNotification::Event method indicates an RTC_EVENT of type RTCE_PRESENCE_DATA, the method's pEvent parameter is an IDispatch pointer for the IRTCPresenceDataEvent interface. The methods of this interface can be used to retrieve information concerning the status code and change in the state of the Session.
Note You must call the IRTCClient::put_EventFilter method and set an event filter mask that includes the RTCEF_PRESENCE_DATA event to enable reception of session state events. If you do not call IRTCClient::put_EventFilter, your application will not receive any events.
