네트워크 구성 인터페이스 포인터 검색

네트워크 구성 하위 시스템이 Notify 개체의 인스턴스 만들기 및 초기화에 설명된 대로 notify 개체의 instance 초기화하면 개체는 INetCfgComponent 및INetCfg 인터페이스 포인터를 받습니다. INetCfgComponent 는 개체가 구성 요소에 액세스하고 제어하는 데 사용할 수 있는 알림 개체의 구성 요소 인터페이스를 가리킵니다. INetCfg 는 알림 개체가 네트워크 구성의 모든 측면에 액세스하는 데 사용할 수 있는 루트 네트워크 구성 인터페이스를 가리킵니다. 다음 코드에서는 이러한 INetCfgComponent 및 INetCfg 인터페이스 포인터를 사용하여 notify 개체에 필요할 수 있는 다른 네트워크 구성 인터페이스를 검색합니다.
