Hämtar pekare för nätverkskonfigurationsgränssnitt

När undersystemet för nätverkskonfiguration initierar en instans av aviseringsobjektet enligt beskrivningen i Skapa och initiera en instans av ett meddelandeobjekttar objektet emot INetCfgComponent och INetCfg gränssnittspekare. INetCfgComponent pekar på det meddelandeobjektets komponentgränssnitt som objektet kan använda för att komma åt och styra komponenten. INetCfg- pekar på det rotnätverkskonfigurationsgränssnitt som aviseringsobjektet kan använda för att få åtkomst till alla aspekter av nätverkskonfigurationen. Följande kod använder dessa INetCfgComponent och INetCfg gränssnittspekare för att hämta andra nätverkskonfigurationsgränssnitt som aviseringsobjektet kan kräva.
