To enable a class to support both nondelegating and delegating IUnknowninterfaces in the same COM object, the Combase.h header file declares the INonDelegatingUnknowninterface. This interface is a version of IUnknownand has three methods:
- INonDelegatingUnknown::NonDelegatingQueryInterface
- INonDelegatingUnknown::NonDelegatingAddRef
-
INonDelegatingUnknown::NonDelegatingRelease
For sample implementations of these methods, see CUnknown::NonDelegatingQueryInterface, CUnknown::NonDelegatingAddRef, and CUnknown::NonDelegatingRelease.
