Re: [lwip-users] Closing tcp-Connection

[Sergio R. Caprile]

In other words, do another call to tcp_new() when you want to reconnect
from tcp_close() in tcp.c:

 * Connection pcbs are freed if not yet connected and may not be referenced
 * any more. If a connection is established (at least SYN received or in
 * a closing state), the connection is closed, and put in a closing state.
 * The pcb is then automatically freed in tcp_slowtmr(). It is therefore
 * unsafe to reference it (unless an error is returned).
