The usage of tcpip_callback should be OK.

There is absolutely *no* need to get the active pcbs! An application 
should work on its own pcb, not on all active pcbs!

I can only repeat myself:
- regarding C knowledge, this is off-topic here. You might have noticed 
noone but Dirk and me answered...
- regarding lwIP: I don't think such a stack is a good project to start 
with C, but if you insist: try reading other applications to see how the 
stack is being used.

What makes you think I haven't read your message? I can imagine bogus 
configuration/usage scenarios where connect/recv works without the 
tcpip_thread mbox allocated.
