NAME¶
ares_cancel - Cancel a resolveSYNOPSIS¶
#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 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).SEE ALSO¶

This function was added in c-ares 1.2.0c-ares 1.6.0 and earlier pass a status of ARES_ETIMEOUT instead of ARES_ECANCELLED.
