When to call setockopt? Before bind () and connect ()?

Question

I inherited the TCP code that called:

bind(tcpSocket, (struct sockaddr*)&server_addr, sizeof(server_addr));

before calling

setsockopt(tcpSocket, SOL_SOCKET, SO_REUSEADDR, &yes, sizeof(int));

Not surprisingly, this led to the message: "The address is already in use." Just changing the order of the calls resolved the problem.

The question arises: in the general case, should I make any calls setsockopt()before the call bind()? Before the challenge connect()?

Answer 1

SO_REUSEADDR bind(). bind() connect(). , , " ".
