I think explicit (a)res_init is an ugly hack, in glibc too.
I would rather call it ares_reload() or something...
If c-ares can only reload dns servers (and other settings) explicitely, then
it ought to export all the files (or registry keys) that it may consider.
I'm not entirely sure if that's a wise thing to do, as tracking those is an
extra dependency for the user.
I'll start with explicit reload function, and add a configurable automatic
kludge that polls every resolution timeout for now. When that works, it's up
to Daniel to include that into trunk or not.
I could see a use for some kind of timeout option that makes c-ares
automatically reload the data after some kind of timeout or similar.
But really, discussions and patches about possible c-ares improvements and
features should be taken to the c-ares mailing list instead of here. Believe
it or not, but c-ares is used by several other softwares than libcurl and
others may have different ideas and suggestions on this topic!
