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.
