The IProvideClassInfo2 interface is a simple extension to IProvideClassInfo for the purpose of making it quick and easy to retrieve an object’s outgoing interface IID for its default event set. The mechanism, the added GetGUID method, is extensible for other types of GUIDs as well.
An object implements this interface to provide type information for its outgoing interfaces.
Call the method in this interface to obtain type information on an object’s outgoing interfaces.
