NAME

ares_cancel - Cancel a resolve

SYNOPSIS

#include <ares.h>
 
void ares_cancel(ares_channel channel)

DESCRIPTION

The ares_cancel function cancels all lookups/requests made on the the name service channel identified by channel. ares_cancel 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.

SEE ALSO

NOTES

This function was added in c-ares 1.2.0

c-ares 1.6.0 and earlier pass a status of , ARES_ETIMEOUTinstead of ARES_ECANCELLED .
