<p>The <strong>Qp0zEndTerminal()</strong> function ends the terminal session
|

|
|
specified by <em>handle</em>.</p>
|
||
|
|
|
||
|
|
<p>The terminal session is ended by:</p>
|

|
|
|
||
|
|
<ol>
|
||
|
|
<li>Ending the terminal window. <br>
|

|

</li>
|
||
|
|
|
||
|
|
<li>Sending the SIGHUP signal to the process group of the interpreter process.
|
||
|
|
<br>
|
||
|
|
</li>
|
||
|
|

|

<li>Closing the pipes connected to the interpreter process.</li>

<p><strong>Qp0zEndTerminal()</strong> waits for the interpreter process to end
|

|
|
before returning to the caller. The status information about how the

interpreter process ended is returned in the optional second parameter.</p>

<h3>Parameters</h3>

information is only returned when the Return_Exit_Status field is set in the

Qp0z_Terminal_Attr_T parameter when the terminal is started by <a href=

<h3>Usage Notes</h3>
|
||
|
|
|
||
|
|
<ol>
|
||
|
|
<li>The default action for the SIGHUP signal is to end the request. The program
|
||
|
|
running in the interpreter process can use a signal handler to catch the signal
|
||
|
|
and perform any necessary cleanup. See <a href="unix5a1.htm">Signals APIs</a>
|
||
|
|
for more information about signals.</li>
|
||
|
