This module contains a bare minimum of functionality to do TCP/IP programming.
This module may disappear after the Socket module of the standard basis
library becomes available. Or, it may remain and be implemented on top of that
module.

- type Address.t
-
the type of IP addresses.
- Host.getByAddress a
-
lookup the hostname (using gethostbyaddr) corresponding to a.
- Host.getByName s
-
lookup the hostname (using gethostbyname) corresponding to s.
- type Port.t
-
the type of TCP ports.
- type t
-
the type of sockets.
- accept s
-
accept a connection on socket s and return the address and
port of the connecting socket, as well as streams corresponding to the
connection.
- connect (h, p)
-
connect to host h on port p, returning the streams
corresponding to the connection.
- listen ()
-
listen to a port chosen by the system. Returns the port and the socket.
- listenAt p
-
listen to port p. Returns the socket.
- shutdownRead ins
-
cause the read part of the socket associated with ins to be shutdown.
- shutdownWrite out
-
cause the write part of the socket associated with out to be shutdown.
