| DNSServiceMetaQuery is based on the Apple, inc. example: |
| http://developer.apple.com/samplecode/DNSServiceMetaQuery/index.html |
| |
| It has been modified to build using OpenCFLite. |
| |
| The program shows how to discover every Bonjour service type |
| being advertised on the local network. You must have the |
| Bonjour SDK installed (or an equivalent Zeroconf service, such |
| as Avahi). You may need to modify project settings to point |
| to the proper location on your system for the necessary |
| service discovery API (dns_sd.h). |
| |
| This sample uses the socket-based DNSServiceDiscovery API to |
| discover all service types being advertised on the network. |
| Starting in Mac OS X 10.3.4, computers on the network which |
| advertise Bonjour services will automatically register an |
| additional PTR record with the name "_services._dns-sd._udp.local." |
| which points to the service type and domain of the advertised |
| service. For example: |
| |
| _services._dns-sd._udp.local. IN PTR _ftp._tcp.local. |
| |
| This sample uses DNSServiceQueryRecord() to send a Multicast |
| DNS query for a PTR record named "_services._dns-sd._udp.local.". |
| The result of the query will be a PTR record which points to the |
| DNS-SD service type and domain. This sample also shows how to |
| parse the resulting PTR record data so that you could potentially |
| pass the results to DNSServiceBrowse(). |
