I am writing a client/server program using C sockets. I am specifying that the server can listen on any network interface by using INADDR_ANY in sockaddr_in.sin_addr.s_addr. This is equivalent to an IP of 0.0.0.0. Is it possible for me to get the actual IP that the server is listening on? (e.g. 192.168.1.100)
I have finally been able to find a solution that works.
Edit: link is dead so see: Internet Archive link.
Hopefully it can be helpful to others as it has been to me.
