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).
SEE ALSO
ares_init(3)
ares_destroy(3)
NOTES
This function was added in -ares 1.2.0
-ares 1.6.0 and earlier pass a status of
ARES_ETIMEOUT
instead of
ARES_ECANCELLED.
