ares_cancel - Cancel a resolve
void ares_cancel(ares_channel channel)

name service channel identified by channel. ares_cancel invokes
the callbacks for each pending query on the channel, passing a status of
ARES_ECANCELLED. These calls give the callbacks a chance to clean up any state which
might have been stored in their arguments. If such a callback invocation adds

current invocation of ares_cancel.
This function was added in c-ares 1.2.0
c-ares 1.6.0 and earlier pass a status of
