[lwip-users] Netconn callback sample?

[Joe Dupre]

I need to convert an application from the raw API to Netconn (just as I think 
I'm getting proficient with the raw API!)

Can someone point me to current sample code demonstrating a Netconn UDP 
connection with callback?  Setting up the netconn seems pretty straightforward, 
but I am having trouble understanding the callback and netbuf handling.

Thanks,
- Joe
