NAME

       ares_cancel - Cancel a resolve

SYNOPSIS

       #include <ares.h>

       void ares_cancel(ares_channel_t *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.
