<p>The <strong>svc_unreg()</strong> function removes mappings between dispatch
|
|
functions and the service procedure that is identified by the <em>prognum</em>
|
|
and <em>versnum</em> parameters. It also removes the mapping between the port
|
|
number and the service procedure, which is identified by the <em>prognum</em>
|
|
and <em>versnum</em> parameters.</p>
