<h3 class="section">14.3 Socket Options</h3>
<p>A subset of socket options are supported, using a fairly general
framework which should make it simple to add more as required - see
<samp><span class="file">SYS:CONTRIB;SB-BSD-SOCKETS:SOCKOPT.LISP</span></samp> for details. The name
mapping from C is fairly straightforward: <code>SO_RCVLOWAT</code> becomes
<code>sockopt-receive-low-water</code> and <code>(setf
sockopt-receive-low-water)</code>.
