| rewrite_host/3 | Allow rewriting the host for tcp_connect/2 and therefore all other predicates to connect a socket. |   | 
| socket_create/2 | Create a socket according to Options. |   | 
| tcp_accept/3 | This predicate waits on a server socket for a connection request by a client. |   | 
| tcp_bind/2 | Bind the socket to Address on the current machine. |   |

| tcp_open_socket/2 | Create streams to communicate to SocketId. |   | 
| tcp_open_socket/3 | Similar to tcp_open_socket/2, but creates two separate sockets where tcp_open_socket/2 would have created a stream pair. |   | 
| tcp_select/3 | Same as the built-in wait_for_input/3. |   | 
| tcp_setopt/2 | Set options on the socket. |   | 
| tcp_socket/1 | Equivalent to socket_create(SocketId, []) or, explicit, socket_create(SocketId, [domain(inet), type(stream)]). |   |
