Cancel a resolve


#include <ares.h>

void ares_cancel(ares_channel_t *channel)


The ares_cancel(3) function cancels all lookups/requests made on the the name service channel identified by channel. Ā 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).
