<p>
The domain to use can be "local" for multicast dns on the local network
(known as mDNS), or it can be the domain of the current host. You can also
use <a class="link" href="gnome-vfs-2.0-gnome-vfs-dns-sd.html#gnome-vfs-dns-sd-list-browse-domains-sync" title="gnome_vfs_dns_sd_list_browse_domains_sync ()"><code class="function">gnome_vfs_dns_sd_list_browse_domains_sync()</code></a> to get a list of domains
that are interested in a particular domain.
</p>
<p>
The type is a string of the form "_type._tcp" or "_type._udp", where type
is a service type registered at http://www.dns-sd.org/ServiceTypes.html.
