Obtaining a Pointer

When the application's implementation of the IRTCEventNotification::Event method indicates an RTC_EVENT enumeration value of RTCE_SESSION_STATE_CHANGE, the method's pEvent parameter is an IDispatch pointer for the IRTCSessionStateChangeEvent interface.

To retrieve this interface, the application should call QueryInterface on IRTCSessionChangeEvent interface, passing the appropriate IID (4F933171-6F95-4880-80D9-2EC8D495D261).

Requirements

OS Versions: Windows CE .NET 4.2 and later.
Header: Rtccore.h, Rtccore.idl.
