SYNOPSIS¶
#include <ares.h>
void ares_cancel(ares_channel channel)
DESCRIPTION¶
The
ares_cancel(3) function cancels all lookups/requests made on the the
name service channel identified by

invokes the callbacks for each pending query on the channel, passing a status

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).

ARES_ETIMEOUT instead of
ARES_ECANCELLED.
