  • Article

3/26/2014

To enable a class to support both nondelegating and delegating IUnknown interfaces in the same COM object, the Combase.h header file declares the INonDelegatingUnknown interface.

This interface is a version of IUnknown and has three methods:

  • INonDelegatingUnknown::NonDelegatingQueryInterface
  • INonDelegatingUnknown::NonDelegatingAddRef
  • INonDelegatingUnknown::NonDelegatingRelease

For sample implementations of these methods, see CUnknown::NonDelegatingQueryInterface, CUnknown::NonDelegatingAddRef, and CUnknown::NonDelegatingRelease.
