The IWbemObjectSink interface is a sink interface used for all types of notifications within the CIMOM programming model. Clients implement this interface to receive both the results of the asynchronous methods of IWbemServices and event notifications. Providers use this interface to provide events and objects.
In general, you call Indicate to provide objects. After that, call SetStatus to indicate the end of the notification sequence. You can also call SetStatus to indicate errors when the sink does not have any objects.
