| |
Hello,
I want to make my protocol connection-oriented. I am really stuck with listen and accept routines :-(. As examples, I took: int tcp_listen_start(struct sock *sk); struct sock *tcp_accept(struct sock *sk, int flags, int *err);
Could anybody briefly explain me how should I implement them? I know the purpose of those functions in the userland. Mainly I have 2 questions: 1. What else besides changing sk->state to TCP_LISTEN should my "listen_start" do? 2. How do I get a pending "socket" in my "accept" function. Should sock_alloc a new one or copy it from some queue?
Thanks for any help! -marek
