ARES_CANCEL(3)ARES_CANCEL(3)NAMEares_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.

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.
