I'm not sure how EventConsumer is supposed to work - maybe one of the real devs can explain how pop works and if it should fail on pop 0 or not.

This seems to work fine: ThreadPool.QueueUserWorkItem((o) => { Log.WriteLine(LogLevel.Notice, "Thread Starting. "); EventConsumer con = new EventConsumer("all", ""); while (true) { Event ev = con.pop(1); Log.WriteLine(LogLevel.Alert, "Event: " + ev.GetHeader("Event-Name")); //freeswitch.msleep(100); } }); With Event ev = con.pop(0) however FS crashes with a System.NullReferenceException (attached) On Tue, Sep 8, 2009 at 5:20 PM, Raffaele P.

Here is an example that, at least on my system (I reached my home pc in the meanwhile), works fine. public class LoadPluginDemo : ILoadNotificationPlugin { delegate void Listener(); private void EventListener() { EventConsumer con = new EventConsumer("all", null); while (true){ Event ev = con.pop(1); Log.WriteLine(LogLevel.Notice, "Got event " + ev.GetHeader("Event-Name")); } } public bool Load() { Log.WriteLine(LogLevel.Notice, "LoadDemo running."); new Listener(EventListener).BeginInvoke(null,null); return true; } } On Tue, Sep 8, 2009 at 18:43, Michael Giagnocavo <[email protected]<mailto:[email protected]>> wrote: That's what his sample does, but he says it crashes.

Guidi Sent: Tuesday, September 08, 2009 10:08 AM To: [email protected]<mailto:[email protected]> Subject: Re: [Freeswitch-users] Subscribing to events in managed C# / .NET Hi, you just have to use delegates to asynchronously call the function containing the loop and return back the control to the calling thread. Here an example (don't have my code at hand, hope it doesn't contain typos). Regards, Raffaele public class TestLoop : ILoadNotificationPlugin { Delegate void DoStuffDelegate(); public void doStuff() { EventConsumer con = new EventConsumer("all", ""); while (true) { Event ev = con.pop(0); Log.WriteLine(LogLevel.Notice, "Event: " + ev.serialized_string); freeswitch.msleep(100); } } public bool Load() { DoStuffDelegate dsdlg = new DoStuffDelegate(doStuff); dsdlg.BeginInvoke(); } } On Tue, Sep 8, 2009 at 08:21, Josh Rivers <[email protected]<mailto:[email protected]>> wrote: Thanks for the response! I have tried putting a long-running loop here, but then it blocks anything else managed from happening: public class TestLoop : ILoadNotificationPlugin { public bool Load() { EventConsumer con = new EventConsumer("all", ""); while (true) { Event ev = con.pop(0); Log.WriteLine(LogLevel.Notice, "Event: " + ev.serialized_string); freeswitch.msleep(100); } } } However, if I fork off a thread here, freeswitch crashes: public class TestLoop : ILoadNotificationPlugin { public bool Load() { ThreadPool.QueueUserWorkItem((o) => { Log.WriteLine(LogLevel.Notice, "Thread Starting. "); EventConsumer con = new EventConsumer("all", ""); while (true) { Event ev = con.pop(0); Log.WriteLine(LogLevel.Notice, "Event: " + ev.serialized_string); freeswitch.msleep(100); } }); return true; } } It doesn't look like this is a good place to start a long-running process?

And let me add that works like a charm :) Ciao, Raffaele On Sun, Sep 6, 2009 at 22:50, Josh Rivers <[email protected]<mailto:[email protected]>> wrote: Is there a way to start this when FreeSWITCH starts? The lua and perl modules have a 'startup-script' configuration preference. Is there something similar in mod_managed? Or is there a way to have an api command executed at a startup? <quote author="Phillip Jones"> Exactly what I was after - thank you!
