Maybe I'm dense, but how can I tell that I should treat this invocation of
CURLMOPT_SOCKETFUNCTION as a signal that DNS resolution is done?
You can't and you shouldn't. libcurl doesn't tell the application when the DNS
resolution is done (or even if DNS resolution is at all performed). You can
still attempt to detect it, but there's no promise it will work.
