30 <p>Apache 2.4 uses <a href="http://www.doxygen.org/">Doxygen</a> to
31 document the APIs and global variables in the code. This will explain
32 the basics of how to document using Doxygen.</p>
34 <div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
36 <h2><a name="brief" id="brief">Brief Description</a> <a title="Permanent link" href="#brief" class="permalink">¶</a></h2>
37 <p>To start a documentation block, use <code>/**</code><br />
38 To end a documentation block, use <code>*/</code></p>
40 <p>In the middle of the block, there are multiple tags we can
43 <div class="example"><p><code>
44 Description of this functions purpose<br />
45 @param parameter_name description<br />
46 @return description<br />
47 @deffunc signature of the function<br />
50 <p>The <code>deffunc</code> is not always necessary. DoxyGen does not
51 have a full parser in it, so any prototype that use a macro in the
52 return type declaration is too complex for scandoc. Those functions
53 require a <code>deffunc</code>. An example (using &gt; rather
56 <div class="example"><p><code>
58 * return the final element of the pathname<br />
59 * @param pathname The path to get the final element of<br />
60 * @return the final element of the path<br />
61 * @tip Examples:<br />
62 * <pre><br />
63 * "/foo/bar/gum" -&gt; "gum"<br />
64 * "/foo/bar/gum/" -&gt; ""<br />
65 * "gum" -&gt; "gum"<br />
66 * "wi\\n32\\stuff" -&gt; "stuff"<br />
67 * </pre><br />
68 * @deffunc const char * ap_filename_of_pathname(const char *pathname)<br />
72 <p>At the top of the header file, always include:</p>
73 <div class="example"><p><code>
75 * @package Name of library header<br />
79 <p>Doxygen uses a new HTML file for each package. The HTML files are named
80 {Name_of_library_header}.html, so try to be concise with your names.</p>
82 <p>For a further discussion of the possibilities please refer to
83 <a href="http://www.doxygen.org/">the Doxygen site</a>.</p>
