<p>The Qp2SignalPase() function posts an i5/OS Portable Application Solutions
|
||
|
|
Environment (i5/OS PASE) signal to an i5/OS PASE program that is already
|
||
|
|
running in the job.</p>

<h3>Parameters</h3>

|
|
<dl>
|
||
|
|
<dt><strong>signo</strong></dt>
|
||
|
|
|
||
|
|
<dd>(Input) Signal number to post. A positive value is an ILE signal number,
|
||
|
|
which causes the system to post a corresponding i5/OS PASE signal. ILE and
|
||
|
|
i5/OS PASE signals correspond if they have the same name (for example,
|
||
|
|
SIGTERM) in a system-provided header file. A negative value is the negation of
|
||
|
|
an i5/OS PASE (and AIX) signal number.</dd>

<h3>Usage Notes</h3>
|
||
|
|
|
||
|
|
<ol>
|
||
|
|
<li>Qp2SignalPase is supported only when an i5/OS PASE program is currently
|
||
|
|
running in the job. This means that Qp2RunPase must be actively called in the
|
||
|
|
job, or the job must be a fork child process.<br>
|
||
|
|
<br>
|
||
|
|
</li>
|
||
|
|
|
||
|
|
<li>Not all ILE signals have an i5/OS PASE equivalent and Qp2SignalPase never
|
||
|
|
converts ILE SIGCHLD to a corresponding PASE signal. This special handling for
|
||
|
|
SIGCHLD avoids duplicate PASE signals for the termination of a single child
|
||
|
|
process (because the system may send both ILE and i5/OS PASE signals to the
|
||
|
|
parent of any fork child process that ends).<br>
|
||
|
|
<br>
|
||
|
|
</li>
|
||
|
|
|
||
|
|
<li>If there is only one i5/OS PASE thread running in the job, the signal
|
||
|
|
remains pending until control is transferred to the i5/OS PASE program. If
|
||
|
|
other i5/OS PASE threads are running at the time Qp2SignalPase is called, the
|
||
|
|
system may chose one of the other threads to deliver the signal.</li>

||
