  59  *              locally connected nets.  For each valid response received,
  60  *              the procedure eachresult is called.  Its form is:

  64  *              struct sockaddr_in raddr;
  65  *              where resp points to the results of the call and raddr is the
  66  *              address if the responder to the broadcast.
