You probably need to set the SO_REUSEADDR socket option; Stevens talks
about this eventually, maybe you haven't read that far. Basically you
need something like
int foo =3D 1;
and then call
setsockopt(listenfd, SOL_SOCKET, SO_REUSEADDR, &foo, sizeof foo);
between the socket() and listen() calls. Check setsockopt(2) and
Stevens for more information (and to make sure I got the arguments and
stuff right!)
