[lwip-users] tcp raw API - accept only one connection

[Palaniappan Chellappan]

Dear all,

I am using tcp raw API, i want to achieve following functionality.

1. Listen on port n
2. Accept a new connection
3. Close Listen port, and don't accept any more connection.
4. Process the new connection
3. After processing, close connection and go to step 1.

***Question:  How to close listening port ? ****
I tried to call tcp_close(), but the port is still binded, i am not
able to bind another pcb to same port again.

Documentation for "tcp_listen_with_backlog()" says "Setting the
connection to LISTEN is an irreversible process"
so its not possible to close listening port ?

regards,
palani
