Description
Implements the IInterface_AddRef method.
Do not call the protected _AddRef method directly. _AddRef is called through the interface to indicate that another object is using the interfaced object's interface pointer. When the other object finishes working with the interface, it calls _Release through the same interface. This allows the interfaced object to free itself when it is no longer used (when the reference count becomes zero).
