P6R::P6ERR P6R::p6ComPtrBase< I >::queryInterface ( const P6R::P6IID &  riid, Q **  ppIface  )

inline

A type safe version of queryInterface().

This is preferred to calling the underlying interfaces queryInterface() method because type safety is added to the second parameter which for p6ICom::queryInterface() is a typeless void**.

Parameters

riid	[ in ] The interface ID of the interface you are requesting.
ppIface	[ out ] The address of a variable which on success will receive the new interface pointer, and on failure will receive NULL.

Returns
