This library contains bindings to the functions in dns_sd.h, which are used to perform generic DNS queries using the macOS resolver. This is the best way to ensure that the query results match the results obtained by other apps on OSX.

Usage example

In a toplevel:

Dnssd.query "dave.recoil.org" Dns.Packet.Q_A;;
- : (Dns.Packet.rr list, Dnssd.error) result =
Ok
  [{Dns.Packet.name = <abstr>; cls = Dns.Packet.RR_IN; flush = false; ttl = 187l; rdata = Dns.Packet.A <abstr>};
   {Dns.Packet.name = <abstr>; cls = Dns.Packet.RR_IN; flush = false; ttl = 187l; rdata = Dns.Packet.CNAME <abstr>};
   {Dns.Packet.name = <abstr>; cls = Dns.Packet.RR_IN; flush = false; ttl = 187l; rdata = Dns.Packet.CNAME <abstr>}]
