<p>The <strong>rapi_release()</strong> API releases the RAPI reservation that
is active currently and closes the open sessions. This call is made implicitly
if the application terminates without closing its RSVP sessions.</p>
<br>
<h3>Parameters</h3>
<dl>
<dt><strong><em>SessID</em></strong></dt>
<dd>(Input) Required<br>
The session ID returned by a successful <strong>rapi_session()</strong>
call.</dd>
</dl>
<br>
<h3>Authorities</h3>
<p>None.</p>
<br>
<h3>Return Value</h3>
<p>Returns 0 if successful.</p>
<p>Returns a RAPI error code if not successful.</p>
<br>
<h3>Error Conditions</h3>
<dl>
<dt><em>[RAPI_ERR_BADSID]</em></dt>
<dd>
<p>The session ID passed to the API did not correspond to a valid RAPI
session.</p>
</dd>
<dt><em>[RAPI_ERR_NORSVP]</em></dt>
<dd>
<p>The RSVP server was not detected. Make sure the server has been
started.&gt;</p>
</dd>
</dl>
<br>
<h3>Usage Notes</h3>
<ol>
<li>The <strong>rapi_session()</strong> API must be called to establish a
session ID to be used with the other RAPI APIs.<br>
<br>
</li>
<li>The RSVP server must be running before any of the RAPI APIs are
called.</li>
</ol>
<br>
