<p>The Mark Heap (CEEMKHP) API returns a token, which can be used with the
|
||
|
|
Release Heap (CEERLHP) API to free a heap storage group. After a CEEMKHP call,
|
||
|
|
all storage subsequently obtained by the CEEGTST API can be freed by a single
|
||
|
|
CEERLHP call. A heap may have multiple marks.</p>

||

|
<!-- Please NOTE: DO NOT DELETE THIS SECTION if this API has no authorities and locks. -->
|
||

<!-- Instead, use the commented out coding below to indicate NONE. -->

<h3>Usage Notes</h3>
|

|
|
|
||
|
|
<ul>
|
||
|
|
<li>
|
||
|
|
<p>The default heap in the activation group cannot be marked.</p>
|
||
|
|
</li>
|
||
|
|
|
||
|
|
<li>
|
||
|
|
<p>Multiple marks are maintained for each heap.</p>
|
||
|
|
|
||
|
|
<p>When a release operation is performed, the specified mark and all subsequent
|
||
|
|
marks are removed from the list of active marks.</p>
|
||
|
|
</li>
|
||
|
|
|
||
|
|
<li>
|
||
|
|
<p>A mark should only be used in release operations. It should not be used as a
|
||
|
|
pointer.</p>
