To make a part connectable as an event source, the part must inherit ODDSConnection. ODDSEventMgr is used to identify the event interface that is supported by the part. Multiple event interfaces are supported by using multiple event managers. Each interface is identified by a universal unique ID. The event managers are added to the connections event manager's list by the part.
Event consumers use the ODDSEventMgrEnum to determine the event interface that the part supports. Sinks are used by other parts to request notification of an event in the event interface. The other parts construct event manager sink lists. The ODDSSinkEnum is used to list the sinks that are on an event manager's sink list.
OpenDoc supports event notification on the OS/2 and Windows platform. There is no event notification support on the AIX platform.
