<div><p>Read this topic collection to learn how to program with the hierarchical
|
||
|
|
file system (HFS).</p>
|
||
|
|
<p>If you need to read to or write from a LAN-attached optical, you will need
|
||
|
|
to use the hierarchical files system (HFS), which is part of i5/OS™.</p>
|
||
|
|
<div class="p">The HFS API support for optical support consists of two parts: <ul><li>An application programming call interface to the hierarchical file system
|
||
|
|
to manipulate objects known as files and directories.</li>
|
||
|
|
<li>An optical or other registered file system that manages the storage devices
|
||
|
|
where the files and directories are stored.</li>
|
||
|
|
</ul>
|
||
|
|
</div>
|
||
|
|
<div class="p">HFS API optical functions include the following: <ul><li>Creating or deleting a directory</li>
|
||
|
|
<li>Opening, reading, or closing a directory</li>
|
||
|
|
<li>Opening, reading, writing, or closing a file</li>
|
||
|
|
<li>Locking or unlocking bytes in a file</li>
|
||
|
|
<li>Getting or setting the size of a file</li>
|
||
|
|
<li>Renaming, copying, deleting, or removing a file</li>
|
||
|
|
<li>Retrieving or changing directory entry attributes</li>
|
||
|
|
</ul>
|
||
|
|
</div>
|

|
|
<p>The following information can help you to program applications that use
|
||
|
|
the HFS with optical devices.</p>
