<h3>Authorities</h3>
|
||
|
|
|
||
|
|
<p>The process calling <strong>Qp0wGetJobID()</strong> must have the
|
||
|
|
appropriate authority to the process whose job number is to be returned. A
|
||
|
|
process is allowed to access the job number for a process if at least one of
|
||
|
|
the following conditions is true:</p>
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li>The process is calling <strong>Qp0wGetJobID()</strong> for its own
|
||
|
|
process.<br>
|
||
|
|
<br>
|
||
|
|
</li>
|
||
|
|
|
||
|
|
<li>The process has *JOBCTL special authority defined in the process user
|
||
|
|
profile or in a current adopted user profile.<br>
|
||
|
|
<br>
|
||
|
|
</li>
|
||
|
|
|
||
|
|
<li>The process is the parent of the process (the process being examined has a
|
||
|
|
parent process ID equal to the process ID of the process calling <strong>
|
||
|
|
Qp0wGetJobID()</strong>).<br>
|
||
|
|
<br>
|
||
|
|
</li>
|
||
|
|
|
||
|
|
<li>The real or effective user ID of the process matches the real or effective
|
||
|
|
user ID of the process calling <strong>Qp0wGetJobID()</strong>.</li>
