<div class="toplang">

</div>
<p>Apache 2.0 uses <a href="http://www.doxygen.org/">Doxygen</a> to
document the APIs and global variables in the code. This will explain
the basics of how to document using Doxygen.</p>
</div>
<div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="brief" id="brief">Brief Description</a></h2>
<p>To start a documentation block, use <code>/**</code><br />
To end a documentation block, use <code>*/</code></p>
<p>In the middle of the block, there are multiple tags we can
use:</p>
<div class="example"><p><code>
Description of this functions purpose<br />
@param parameter_name description<br />
@return description<br />
@deffunc signature of the function<br />
</code></p></div>
<p>The <code>deffunc</code> is not always necessary. DoxyGen does not
have a full parser in it, so any prototype that use a macro in the
return type declaration is too complex for scandoc. Those functions
require a <code>deffunc</code>. An example (using &gt; rather
than >):</p>
<div class="example"><p><code>
/**<br />
* return the final element of the pathname<br />
* @param pathname The path to get the final element of<br />
* @return the final element of the path<br />
* @tip Examples:<br />
* <pre><br />
* "/foo/bar/gum" -&gt; "gum"<br />
* "/foo/bar/gum/" -&gt; ""<br />
* "gum" -&gt; "gum"<br />
* "wi\\n32\\stuff" -&gt; "stuff"<br />
* </pre><br />
* @deffunc const char * ap_filename_of_pathname(const char *pathname)<br />
*/
</code></p></div>
<p>At the top of the header file, always include:</p>
<div class="example"><p><code>
/**<br />
* @package Name of library header<br />
*/
</code></p></div>
<p>Doxygen uses a new HTML file for each package. The HTML files are named
{Name_of_library_header}.html, so try to be concise with your names.</p>
<p>For a further discussion of the possibilities please refer to
<a href="http://www.doxygen.org/">the Doxygen site</a>.</p>
