Imported from Redmine:

int recv_autoenable (int sfd, struct autoenable *ae) {

  // FIXME: check size
  if (!dr_read(sfd,(char*)ae,sizeof(struct autoenable))) {
    return 0;
  }

  /* Now we should have the autoenable info with the values in */
  /* network byte order, so we put them in host byte order */
  ae->last = ntohl (ae->last);

  return 1;
