<h3>Usage Notes</h3>
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li>
|
||
|
|
<p>Multiple user call stack entry termination user exit procedures can be
|
||
|
|
registered for each call stack entry.</p>
|
||
|
|
</li>
|
||
|
|
|
||
|
|
<li>
|
||
|
|
<p>Call stack entry termination user exit procedures run in first in/first out
|
||
|
|
(FIFO) order. If a procedure causes any of the following, the remaining
|
||
|
|
procedures are not run:</p>
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li>
|
||
|
|
<p>The call to a call stack entry termination user exit procedure fails.</p>
|
||
|
|
</li>
|
||
|
|
|
||
|
|
<li>
|
||
|
|
<p>An exception is not handled.</p>
|
||
|
|
</li>
|
||
|
|
|
||
|
|
<li>
|
||
|
|
<p>Control has moved past the invocation of the call stack entry termination
|
||
|
|
user exit procedure. For example, the resume cursor has been moved, or an
|
||
|
|
out-of-scope jump, such as <em>longjmp()</em> in ILE C, has been used.</p>
|
||
|
|
</li>
|
||
|
|
</ul>
|
||
|
|
</li>
|
||
|
|
|
||
|
|
<li>
|
||
|
|
<p>The message CEE0257 occurs only if the pointer contained in the procedure
|
||
|
|
parameter is not a procedure pointer. This does not verify that a call through
|
||
|
|
that pointer will be successful. For example, the call may fail because the
|
||
|
|
activation group containing the procedure no longer exists.</p>
|
||
|
|
</li>
|
||
|
|
</ul>
