.SH DESCRIPTION |
|
The \fBares_cancel\fP function cancels all lookups/requests made on the the |
|
name service channel identified by \fIchannel\fP. \fBares_cancel\fP invokes |
|
the callbacks for each pending query on the channel, passing a status of |
|
.BR 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 \fInot\fP be cancelled by the |
|
current invocation of \fBares_cancel\fP. |
