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
DirectShow applications and DirectShow filters have different include file and link library requirements.
For more information, see Setting Up the Build Environment.
OS Versions: Windows CE 2.12 and later. Version 2.12 requires DXPAK 1.0 or later.
