Intercom interfaces form the basis of the cross language API provided by the user library. The interfaces define the available methods that can be called through the interface pointers given to the clients.

Each interface automatically inherits from the base IUnknown interface, which provides the clients a way to perform reference counting and the ability to query for other interfaces the object might implement.
