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.

SEE ALSO

       ares_init(3) ares_destroy(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.
