Hello -
Could anyone point me to the correct way to close a connection using
tcp_close in RAW mode?
Currently, I have a snippet like the following in my receive callback function:
if (pcb->state >= FIN_WAIT_1 && pcb->state <= CLOSING) {
tcp_close(pcb);
return;
}
I don't like the fact that the application is probing into the PCB
structures..But then again, this is raw mode, so it might be ok. Any
thoughts?
Initially I only checked if pcb->state > ESTABLISHED, but that ended
up calling tcp_close twice under certain circumstances, and as I found
out after a long debugging session, you don't want to close a socket
that has already been closed since that will lead to wierd memory
corruption issues depending on the sequence of packets received.
Thanks,
Siva
