I generally don't like pimping my warez, but IMNSHO you might want to try
this:

See resolve_addrinfo() at the bottom of the source file for an example of
how to use the struct addrinfo-based API.

I've used c-ares, ADNS, etc for years. They were all poorly designed, IMHO.
They worked sort-of-okay for simple A lookups, but were a PITA for anything
more sophisticated. Plus, I hated being forced to use callbacks.
