3.1.4.17.3 Get Properties Within an Instance of a Class
The server passes class name, the key property values through the IWbemClassObject instance, and a pointer to the IWbemObjectSink object to the provider. The provider returns the IWbemClassObject instance containing the nonkey properties for the given instance through the IWbemObjectSink::Indicate method. The provider returns WBEM_E_NOT_FOUND through the IWbemObjectSink::SetStatus method if the instance referred by the key properties is not found. On success, the provider sends the final status info using the IWbemObjectSink::SetStatus method.
