But res_init is not part of CURL, so the app wont be transferable to other
platforms.

That sounds like a name resolver problem. So maybe something needs to be
reset/reloaded when your internet connection has gone and come back.

If you try to call res_init() when you get CURLE_COULDNT_RESOLVE_HOST and
then
call curl again, does it make any difference?
