14.3 Socket Options

A subset of socket options are supported, using a fairly general framework which should make it simple to add more as required - see SYS:CONTRIB;SB-BSD-SOCKETS:SOCKOPT.LISP for details. The name mapping from C is fairly straightforward: SO_RCVLOWAT becomes sockopt-receive-low-water and (setf sockopt-receive-low-water).
