Hey Marco,

I need to change the

fly" in its idle state.
Really? Very limited resources, using netconn and this should help?
Keeping that aside, for the thread using netconns, the pcb is never
"idle": it's listening. You're producing
race conditions here. This is a bad example for this list!
Keeping even that aside, accessing a struct's member should be
prevented and *is* prevented by the
lwip headers, so struct tcp_pcb is unknown to your code (and it's
good like that!)
