<p>The <strong>svc_tp_create()</strong> function creates a server handle for
the network specified by <em>netconf</em>, and registers itself with the RPC
service package (RPCBind).</p>
<br>
<h3>Parameters</h3>
<dl>
<dt><strong>dispatch()</strong> &nbsp;(Input)&nbsp;</dt>
<dd>The server dispatch function. <em>dispatch()</em> is called when there is a
remote procedure call for the given <em>prognum</em> and <em>versnum</em>. The
call to <em>dispatch</em> requires calling <strong>svc_run()</strong> on the
server side.<br>
<br>
</dd>
<dt><strong>prognum</strong> &nbsp;(Input)&nbsp;</dt>
<dd>The program number of the remote program.<br>
<br>
</dd>
<dt><strong>vernum</strong> &nbsp;(Input)&nbsp;</dt>
<dd>The version number of the remote program.<br>
<br>
</dd>
<dt><strong>netconf</strong> &nbsp;(Input)&nbsp;</dt>
<dd>The transport protocol to use.</dd>

<h3>Return Value</h3>

the service handle.</td>

<h3>Error Conditions</h3>
<p>This API calls <strong>svc_tli_create()</strong> and
<strong>svc_reg()</strong> functions in order to perform its task. It inherits
all error conditions from those functions, except
<strong>setnetconfig()</strong> and <strong>getnetconfig()</strong> errors and
RPC_UNKNOWNADDR from <strong>svc_reg()</strong>.</p>

used:</p>
<pre>

nconf);
if (transp == (SVCXPRT *)NULL) {
