[Freeswitch-users] Subscribing to events in managed C# / .NET

[Michael Giagnocavo]

Hi,

                Can you please elaborate on the crash you receive when you queue a thread during load?

Thanks,
Michael

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?

Thanks!
Josh

Yes!

public class LoadDemo : ILoadNotificationPlugin {
    public bool Load() {
        Log.WriteLine(LogLevel.Notice, "LoadDemo running.");
        return true;
    }
}

this example is from Michael Giagnocavo's Demo.csx which you can find into the mod_managed svn.

And let me add that works like a charm :)

Ciao,

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?

Exactly what I was after - thank you!
