This module contains a bare minimum of functionality to do TCP/IP programming. This module is implemented on top of the <tt>Socket</tt> module of the Standard Basis Library. We encourage you to use the standard <tt>Socket</tt> module, since we may eliminate <tt>MLton.Socket</tt> some day.
</p>
<ul>
<li>
<p>
<tt>type Address.t</tt>
</p>
</li>
<ul>
the type of IP addresses.
</ul>
<li class="gap">
<p>
<tt>Ctl.getERROR s</tt>
</p>
</li>
<ul>
like the Basis Library's <tt>Socket.Ctl.getERROR</tt>, except that it returns more information. <tt>NONE</tt> means that there was no error, and <tt>SOME</tt> means that there was an error, and provides the error message and error code, if any.
</ul>
<li class="gap">
<p>
<tt>Host.getByAddress a</tt>
</p>
</li>
<ul>
looks up the hostname (using <tt>gethostbyaddr</tt>) corresponding to <tt>a</tt>.
</ul>
<li class="gap">
<p>
<tt>Host.getByName s</tt>
</p>
</li>
<ul>
looks up the hostname (using <tt>gethostbyname</tt>) corresponding to <tt>s</tt>.
</ul>
<li class="gap">
<p>
<tt>type Port.t</tt>
</p>
</li>
<ul>
the type of TCP ports.
</ul>
<li class="gap">
<p>
<tt>type t</tt>
</p>
</li>
<ul>
the type of sockets.
</ul>
<li class="gap">
<p>
<tt>accept s</tt>
</p>
</li>
<ul>
accepts a connection on socket <tt>s</tt> and return the address and port of the connecting socket, as well as streams corresponding to the connection.
</ul>
<li class="gap">
<p>
<tt>connect (h, p)</tt>
</p>
</li>
<ul>
connects to host <tt>h</tt> on port <tt>p</tt>, returning the streams corresponding to the connection.
</ul>
<li class="gap">
<p>
<tt>fdToSock fd</tt>
</p>
</li>
<ul>
coerces a file descriptor to a socket.
</ul>
<li class="gap">
<p>
<tt>listen ()</tt>
</p>
</li>
<ul>
listens to a port chosen by the system. Returns the port and the socket.
</ul>
<li class="gap">
<p>
<tt>listenAt p</tt>
</p>
</li>
<ul>
listens to port <tt>p</tt>. Returns the socket.
</ul>
<li class="gap">
<p>
<tt>shutdownRead ins</tt>
</p>
</li>
<ul>
causes the read part of the socket associated with <tt>ins</tt> to be shutdown.
</ul>
<li class="gap">
<p>
<tt>shutdownWrite out</tt>
</p>
</li>
<ul>
causes the write part of the socket associated with <tt>out</tt> to be shutdown. </ul>
</ul>
