Apache HTTP Server Version 2.2
Apache HTTP Server Version 2.2
This document refers to a legacy release (2.2) of Apache httpd. The active release (2.4) is documented here. If you have not already upgraded, please follow this link for more information.
You may follow this link to go to the current version of this document.
Apache 2.0 uses Doxygen to document the APIs and global variables in the code. This will explain the basics of how to document using Doxygen.
To start a documentation block, use /**
To end a documentation block, use */
In the middle of the block, there are multiple tags we can use:
Description of this functions purpose
@param parameter_name description
@return description
@deffunc signature of the function
The deffunc 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 deffunc. An example (using > rather
than >):
/**
* return the final element of the pathname
* @param pathname The path to get the final element of
* @return the final element of the path
* @tip Examples:
* <pre>
* "/foo/bar/gum" -> "gum"
* "/foo/bar/gum/" -> ""
* "gum" -> "gum"
* "wi\\n32\\stuff" -> "stuff"
* </pre>
* @deffunc const char * ap_filename_of_pathname(const char *pathname)
*/
At the top of the header file, always include:
/**
* @package Name of library header
*/
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.
For a further discussion of the possibilities please refer to the Doxygen site.
