NAME
ares_cancel - Cancel a resolve
SYNOPSIS
#include <ares.h>
ares_cancel(3) channel)
DESCRIPTION
The ares_cancel(3) function cancels all lookups/requests made on the
the name service channel identified by channel. ares_cancel(3) 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 a new request to the channel, that request
will not be cancelled by the current invocation of ares_cancel(3).

NOTES
This function was added in c-ares 1.2.0
c-ares 1.6.0 and earlier pass a status of ARES_ETIMEOUT instead of
ARES_ECANCELLED.
