Hi there,

mod_managed exposes EventReceivedFunction such that:

 Session.EventReceivedFunction = (e) =>
 {
       Log.WriteLine(LogLevel.Alert, "Received Event {0}", e.ToString());
       return "";
 };

should trap all events to which i subscribe.


But how do I subscribe to events? What is the .NET / managed equivalent of:

switch_event_bind(const char *id, switch_event_types_t event, const char *subclass_name, switch_event_callback_t callback, void *user_data);



Thank you!

You can call switch_event_bind directly, but I doubt that’ll achieve what you want.

My guess is that it works the same as LUA or any of the other plugins – whatever higher level API is exposed for setting up events should make things just work.

Where can I find EventConsumer?? I search the wiki and contrib\

Thanks

try something like this

EventConsumer con = new EventConsumer("all", "");
Event ev = con.pop(0);

see lua sample -

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?

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

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

Hi,

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

Thanks,
Michael

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).

   public class TestLoop : ILoadNotificationPlugin

         Delegate void DoStuffDelegate();
 
       public void doStuff()
        {

            DoStuffDelegate dsdlg = new DoStuffDelegate(doStuff);

That’s what his sample does, but he says it crashes.

What is:

Why aren't you using Thread.Sleep?

Well, I can't see any delegate in josh sample, just a ThreadPool.QueueUserWorkItem. 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;
   }
}

Yeah, probably just using con.pop(1) - that waits for an event to be caught, instead than con.pop(0), thus avoiding "sleeps" would do the trick
