<pre style="margin-left: 2em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">First off, apologies for bringing this up now rather than earlier, but I did not think of this until over this past weekend.
The main reason that ast_dns_resolve_async() returns an ast_dns_query is so that the query can be canceled by calling ast_dns_resolve_cancel(). The problem is that there is nothing that prevents the caller of ast_dns_resolve_async() from doing unwanted operations such as adding DNS results/records, or attempting to read results from the query while an async thread is currently writing them.
What I propose here is returning something other than an ast_dns_query from this function. The structure returned from ast_dns_resolve_async() could be passed to ast_dns_resolve_cancel(), and that's it. This would be similar to how ast_dns_resolve_recurring() works.</pre>

Minimal changes have been made as required based on real usage and getting a feel for it. As it is the core functionality is present. Resolvers can register, queries can be made (async / sync).
As the API was basically copy/pasted from the wiki page there still remain stubs to be filled in for higher level functionality (such as parsing and query sets).</pre>
