    I agree that in most cases using .Detach() is appropriate. But what if you want to continue to use the object after the consuming function returns? GetThingy(&sp); UseThingyEatsInput(sp.Detach()); UseThingy(sp); // gets nullptr! I suppose the .Detach() solution can still be used with a temporary: UseThingyEatsInput(SmartPointerType(p).Detach()); Effectively this becomes a .GetAddRefdPointer().

    Well, uhm... if you want to continue to use the object, then don't throw it away before you're done with it. In other words, call CoUnmarshalInterface instead of CoGetInterfaceAndReleaseStream (Raymond's suggestion 2).
