ARES_CANCEL 3 "31 March 2004"
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 c-ares 1.2.0
c-ares 1.6.0 and earlier pass a status of
ARES_ETIMEOUT instead of
ARES_ECANCELLED . AUTHOR
