5.5.1 Event Mechanism

The IP Media (IPML) demo uses the SRL mechanism to retrieve events. When an event occurs, SRL calls event handlers automatically. All events are received by the SRL and then passed to the callback_hdlr( ) function for handling.

In the initialization phase of the demo the init( ) function sets up the call-back handler, by calling PDLsr_enbhdlr( ).

Refer to Chapter 6, "Demo State Machines" for more detailed event handling information.
