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

[Josh Rivers]

A new discovery:        public bool Load()
        {
            ThreadPool.QueueUserWorkItem((o) =>
            {
                Log.WriteLine(LogLevel.Notice, "Thread Starting. ");
                EventConsumer con = new EventConsumer("all", "");
                while (true)
                {
                    Event ev = con.pop(0);
                    if (ev == null) continue;
                    Log.WriteLine(LogLevel.Notice, "Event: " +
ev.serialized_string);
                }
            });
            return true;
        }
Does not crash. (Adding the null check prevents crash.) The backgrounded
loop runs fine. Looks like the event object goes straight to pinvokes, so a
null result just crashes?

I like the idea of a 'startup-script' for mod_managed. It would also be
excellent if there was an event or message  informing the background code to
terminate nicely when the module reloads.
