3.1.4.17.4 Get Properties Within a Class
The server passes the class name and a pointer to an IWbemObjectSink object to the provider. The provider returns the class metadata through the IWbemClassObject instance containing the metadata of the given class, through the IWbemObjectSink::Indicate method. The provider returns WBEM_E_NOT_FOUND through the IWbemObjectSink::SetStatus method if the class is not found. On success, the provider sends the final status using the IWbemObjectSink::SetStatus method.
