Re: [Freeswitch-users] C# new ESLevent(

18 Jan 2011

      I don't know about ESL-still very new to FS. I should look at that. If you 
figure it out, send some of the code here.

I used this to notify my running DLL that a new one is being loaded, then 
start a new thread to pop events. It works and pulls events fine. I still 
have a problem where freeswitch crashes toward the end of it's shutdown so 
something is not being freed or is corrupted.(switch_core_memory.c:587 
Stopping memory pool queue) is the last written on the screen.
If someone knows why, let me know.

Does someone have an example of the C# EslConnection method SendEvent with 
a
new ESLevent ?
Like how to fill in any info on the ESLevent object before sending it?
Thanks,
