I have noticed the wiki is pretty much non-existant on the subject of custom events.
Probably true :( The best docs for this are generated by doxygen : http://www.freeswitch.org/docs/switch__types_8h.html#a658
From my understanding of the system thus far, I could create a number of custom events that my applications can react to and perform busienss logic.
Correct
One specific example: I could connect to FS and fire an event "MYPROJECT::OUTBOUND_DIAL" which a separate application could listen for and process further. I might therefore have a chain of small apps developing these and reacting at various stages.
Is my understanding correct? Can I therefore register an application to listen for MYPROJECT::MY_CUSTOM_EVENT and wait until another of my apps fires it? The next obvious question is how parameter handling works...
All Correct. Params are handled as name/value pair headers in the event. To add headers see switch_event_add_header/ switch_event_add_header_string functions. You can access these with switch_event_get_header. Events also have bodies switvh_event_add_body/switch_event_get_body. A full detail of the event functions is at http://www.freeswitch.org/docs/switch__event_8h.html .
But I shall try to walk before running...
Thanks,
