You should specify the same interface you discovered via the service browser/resolver.

You should specify the same protocol you discovered via the service browser/resolver.

You should specify the same host name you found via the service resolver.

HINFO? I thought you were interested in the address records (i.e. A or AAAA).

Leave that to the implementation, pass 0 here.

Hey, read the docs, that's why I wrote them. They might not be
complete, but they do explain what CACHE EXHAUSTED means.

You'll get a couple of callbacks. If you don't care about CACHE
EXHAUSTED then ignore it.

Read the DNS-SD spec.

This is an API to lookup low-level RRs. The parameters are hence in
the format those low-level RRs use. i.e. fqdn.
