|
|
in the QOPT file system through either the integrated file system interface
|
|
or APIs provided by a hierarchical file system (HFS).</span></p>
|
|
<div class="section"><p>Whereas the integrated file system is based on the Integrated
|
|
Language Environment<sup>®</sup> (ILE) program model, HFS is based on the original iSeries™ server
|
|
program model.</p>

</div>
|
|
<div class="section"><p>The HFS APIs allow you to perform a few additional operations
|
|
that the integrated file system does not support. In particular, you can
|
|
use HFS APIs to access and change directory extended attributes (also called <em>directory
|
|
entry attributes</em>) or to work with held optical files. Be aware that the
|
|
naming rules for using HFS APIs are different from the naming rules for APIs
|
|
using the integrated file system interface.</p>
|
|
</div>
