NAME

       ares_cancel - Cancel a resolve

SYNOPSIS

       #include <ares.h>

       void ares_cancel(ares_channel channel)

DESCRIPTION

       The ares_cancel function cancels all lookups/requests made on the the 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  a  new request to the channel, that request will not be cancelled by the
       current invocation of ares_cancel.

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.
