<h2>Hierarchical File System APIs</h2>
|
||
|
|
|
||
|
|
<p>For information on the Hierarchical File System (HFS) APIs, see the following:</p>
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li><a href="hfs1a.htm">HFS concepts</a></li>
|
||
|
|
|
||
|
|
<li><a href="hfs1b.htm">HFS Use--Requirements</a></li>
|
||
|
|
|
||
|
|
<li><a href="hfs1c.htm">HFS Directory Entry Attributes</a></li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p>The hierarchical file system (HFS) APIs include:</p>
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li><a href="hfs2.htm">Hierarchical File System Access APIs</a></li>
|
||
|
|
|
||
|
|
<li><a href="hfs3.htm">File System Registration APIs</a></li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p>The HFS APIs and the functions they support are part of the i5/OS<SUP>(R)</SUP> program.
|
||
|
|
These APIs provide applications with a single, consistent interface to the file
|
||
|
|
systems registered with the hierarchical file system on your iSeries server.
|
||
|
|
They automatically support the document library services (DLS) file system and
|
||
|
|
the optical file system (QOPT), and they can also support user-written file
|
||
|
|
systems.</p>
|
||
|
|
|
||
|
|
<p>With HFS APIs you can work with nonrelational data stored in objects, such
|
||
|
|
as directories and files in existing file systems. You can also perform such
|
||
|
|
tasks as creating and deleting directories and files, reading from and writing
|
||
|
|
to files, and changing the directory entry attributes of files and
|
||
|
|
directories.</p>
|
||
|
|
|
||
|
|
<p>The following diagram shows the relationship of the HFS APIs to your
|
||
|
|
applications and to other file systems:</p>

<!-- If you are working with the document library services (DLS) file system,
|
||
|
|
refer to the

|
||
|
|
|
||
|
|
<p>If you are working with the optical file system (QOPT), refer to <a
|
||
|
|
href="../rzau8/kickoff.htm">Optical device programming</a>. If you are not writing applications, but instead are
|
||
|
|
creating or installing a new file system for other programmers to use with the
|
||
|
|
HFS APIs, turn to <a href="hfs3.htm">User-Written File Systems and HFS</a>.</p>
