Sockets Server

A server accepts incomming connections from clients by

1. Creating a socket
2. Binding the socket to a specified port
3. Setting the socket to listen (act as a server), and then
4. Waiting to accept incomming connections

For example

socket( S, PF_INET, SOCK_STREAM, (getprotobyname('tcp'))[2] );
bind( S, sockaddr_in( $port, INADDR_ANY ) );
listen( S, SOMAXCONN );
accept( C, S );
