  • Article

1/6/2010

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.

Requirements

Windows Embedded CE Windows CE 2.12 and later
Note Microsoft DirectShow applications and DirectShow filters have different include file and Library requirements
