I read about NSNetServiceBrowser and I wrote a small app that could
detect the rendezvous / bonjour iTunes sharing service on the network
using NSNetServiceBrowser and NSNetService with a service type of
_daap._tcp.
NSNetService returns a struct sockaddr that has the IP address and
the port of the machine broadcasting the service. However, I would
also like to get the hostname / Computer Name of the machine
broadcasting this service. How could I obtain this info?
There's no easy way to retrieve the Computer Name of the service, but
starting in Tiger, you'll be able to get the hostname after resolving
the service by using the new NSNetService "hostName" method. If you
need to get the hostname in Panther, then you'll need to use
DNSServiceResolve() located in /usr/include/dns_sd.h.
Since an Apple employee has set the precedent, does this mean we are
now allowed to discuss the API extensions to 10.4? It's surely in
Apple's interest for as many of us as possible to be able to support
Tiger sooner rather than later.
