Send Feedback

When a client wants to subscribe to a connectivity callback service, the client must implement the interface of interest, and register the callback service.

To register a connectivity callback service

1. Implement the callback interface on a class object.
2. Get an ICcService interface from the target service.
3. Find an IConnectionPointContainer using IUnknown::QueryInterface on the interface returned in step 2.
4. Call IConnectionPointContainer::FindConnectionPoint with refiid == guid of the callback interface.
5. Call IConnectionPoint::Advise to pass in the pointer to the IUnknown interface of the class object from step 1.
6. After receiving all the status notifications, call IConnectionPoint::Unadvise with the cookie value from step 5.
