DESCRIPTION

       The DNSServiceCreateConnection() function allows the creation of a connection to the mDNS daemon in order to register  multiple	individual
       records.

       The  DNSServiceRegisterRecord()	function  uses the connection created by DNSServiceCreateConnection() to register a record. Name conflicts
       that occur from this function should be handled by the client in the callback.

       The DNSServiceAddRecord() call adds a DNS record to a registered service. The name of the record is the same as	registered  service  name.
       The  RecordRef  argument  to  DNSServiceAddRecord()  points  to an uninitialized DNSRecordRef. After successful completion of DNSServiceAd-
       dRecord(), the DNS record can be updated or deregistered by passing the DNSRecordRef initialized by DNSServiceAddRecord() to  DNSServiceUp-
       dateRecord() or to DNSServiceRemoveRecord().

       The  DNSServiceUpdateRecords()  call  updates  the DNS record of the registered service. The DNS record must be the primary resource record
       registered using DNSServiceRegister() or a record added to a registered service using DNSServiceAddRecord() or an individual  record  added
       via DNSServiceRegisterRecord().

       The DNSServiceRemoveRecord() call removes a record that was added using DNSServiceAddRecord() or DNSServiceRegisterRecord().

       The  sdRef  argument  points  to  DNSServiceRef initialized from a call to DNSServiceRegister(). If the sdRef argument is passed to DNSSer-
       viceRefDeallocate() and the service is deregistered DNS records added via DNSServiceAddRecord() are invalidated and cannot be further used.
       The flags argument is currently ignored and reserved for future use. The rrtype parameter value indicates the type of the DNS record. Suit-
       able values for the rrtype parameter are defined in <dns_sd.h>: kDNSServiceType_TXT, for example. The rdata  argument  points  to  the  raw
       rdata  to be contained in the resource record. The ttl value indicates the time to live of the resource record in seconds. A ttl value of 0
       should be passed to use a default value.

RETURN VALUES

       The DNSServiceCreateConnection function returns kDNSServiceErr_NoError on success. Otherwise,  an  error  code  defined	in  <dns_sd.h>	is
       returned to indicate the specific failure that occurred.
