From MoodleDocs
The link "the documentation for datalib.php" appears to be broken. I believe that it should link to http://phpdocs.moodle.org/moodlecore/_lib---datalib.php.html instead of http://moodle.sourceforge.net/dhawes-phpdoc/moodlecore/_lib_datalib_php.html I'm not sure though because the file is empty. Hopefully someone else knows now to fix this.
