“ ThreadPool.QueueUserWorkItem((o) =>”
That starts a lambda, which is compiled to a delegate, same as anonymous methods.
Guess I’ll wait for him to respond on the crash he gets.

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;
}
}

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();
}
}

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 bool Load() {
Log.WriteLine(LogLevel.Notice, "LoadDemo running.");

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?
