ares_cancel(3) Library Functions Manual ares_cancel(3)
NAME
ares_cancel - Cancel a resolve
SYNOPSIS
#include <ares.h>
void ares_cancel(ares_channel_t *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).
