  12  *
  13  * sdRef:           A pointer to an uninitialized DNSServiceRef. Deallocating
  14  *                  the reference (via DNSServiceRefDeallocate()) severs the
  15  *                  connection and deregisters all records registered on this connection.
  16  *
  17  * pid :            Process ID of the delegate
  18  *
  19  * uuid:            UUID of the delegate
  20  *
  21  *                  Note that only one of the two arguments (pid or uuid) can be specified. If pid
  22  *                  is zero, uuid will be assumed to be a valid value; otherwise pid will be used.
  23  *
  24  * return value:    Returns kDNSServiceErr_NoError on success, otherwise returns
  25  *                  an error code indicating the specific failure that occurred (in which
  26  *                  case the DNSServiceRef is not initialized). kDNSServiceErr_NotAuth is
  27  *                  returned to indicate that the calling process does not have entitlements
  28  *                  to use this API.
