|
.SH NAME |
|
ares_cancel \- Cancel a resolve |
|
.SH SYNOPSIS |
|
.nf |
|
#include <ares.h> |
|
|
|
void ares_cancel(ares_channel_t *\fIchannel\fP) |
|
.fi |
|
.SH DESCRIPTION |
|
The \fBares_cancel(3)\fP function cancels all lookups/requests made on the the |
|
name service channel identified by \fIchannel\fP. \fBares_cancel(3)\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(3)\fP. |
