Product Description
Figure 2. Event Notification Framework
Intel
®
Dialogic system software components, such as device drivers and firmware, are the supplier
objects. They generate events that are broadcast to consumer objects via the event notification
channels. The DlgAdminConsumer class allows you to instantiate consumer objects and register
them to receive events from one of the event notification channels. The CEventHandlerAdaptor
class allows you to instantiate user-defined event handler objects that are invoked when
DlgAdminConsumer objects receive events.
