The ITQOSEvent interface contains methods that retrieve the description of quality of service (QOS) events. When the application's implementation of the ITTAPIEventNotification::Event method indicates a TAPI_EVENT equal to TE_QOSEVENT, the method's pEvent parameter is an IDispatch pointer for the ITQOSEvent interface. The methods of this interface can be used to retrieve information concerning a QOS event that has occurred.
Note You must call the
ITTAPI::put_EventFilter method and set an event filter mask that includes the TE_QOSEVENT to enable reception of QOS events. If you do not call ITTAPI::put_EventFilter, your application will not receive any events. For more information, see the
Events overview.
