&nbsp;&nbsp;Syntax<br>
<!-- iddvc RMBR -->

<p>The <strong>clnt_geterr()</strong> function copies the error structure out
of the client handle to the structure at address errp.</p>
<br>
<h3>Parameters</h3>
<dl>
<dt><strong>clnt</strong> &nbsp;(Input)&nbsp;</dt>
<dd>A pointer to the client handle.<br>
<br>
</dd>
<dt><strong>errp</strong> &nbsp;(Output)&nbsp;</dt>
<dd>A pointer to the error structure.</dd>
</dl>
<br>
<h3>Authorities</h3>
<p>No authorization is required.</p>
<br>
<h3>Return Value</h3>
<p>None.</p>
<br>
<h3>Error Conditions</h3>
<p>When an exception occurs, <strong>clnt_geterr()</strong> tries to set
RPC_INTR in the client handle. This status can be retrieved by another valid
<strong>clnt_geterr()</strong> call. If the attempt was unsuccessful, no error
indication is given.</p>

<h3>Example</h3>

<p>The following example shows how <strong>clnt_geterr()</strong> is used:</p>
<pre>
#include &lt;stdio.h&gt;
#include &lt;rpc/rpc.h&gt;
#include &lt;sys/time.h&gt;
main()
{
u_long procnum;
CLIENT *clnt;
enum clnt_stat cs;
struct rpc_err client_error;
struct timeval total_timeout;
int intsend, intrecv;
...
/* Call the remote procedure that is associated with client */
cs = clnt_call(clnt, procnum, xdr_int,
(caddr_t)&amp;intsend, xdr_int,
(caddr_t)&amp;intrecv, total_timeout);
if (cs != RPC_SUCCESS){
<strong>clnt_geterr</strong>(clnt,&amp;client_error);
...
exit(1);
}
