  // its work once.  It does, however, track the number of times it's
  // called (see <open_services>).  It is fully thread-safe.  Return 0
  // if successful, -1 with errno set if failure.  You can provide
  // your program a set of default <svc.conf> entries by setting
  // <ignore_default_svc_conf_file> to non-zero and use
  // <default_svc_conf_entries> before calling <open_services>.  In
  // addition, you can <skip_service_config_open> altogether, which is
  // important if the ORB is linked in via the
  // <ACE_Service_Configuator>, which is non-reentrant.
