<h3>Usage Notes</h3>
|
|
|
|
<ol>
|
|
<li>The <strong>Qp0wGetPid()</strong> function provides an i5/OS-specific way
|
|
to obtain the process ID of the calling process. It performs the same function
|
|
as <strong>getpid()</strong>.<br>
|
|
<br>
|
|
</li>
|
|
|
|
<li><strong>Qp0wGetPid()</strong> enables a process for signals if the process
|
|
is not already enabled for signals. For details, see (see <a href=
|
|
"sigesig.htm">Qp0sEnableSignals()--Enable Process for Signals</a>.</li>
