Description
Find overridden theme functions. Called by themes and/or theme engines to easily discover theme functions.

Code
function drupal_find_theme_functions($cache, $prefixes) {
$templates = array();
$functions = get_defined_functions();
foreach ($cache as $hook => $info) {
foreach ($prefixes as $prefix) {
if (!empty($info['pattern'])) {
$matches = preg_grep('/^' . $prefix . '_' . $info['pattern'] . '/', $functions['user']);
if ($matches) {
foreach ($matches as $match) {
$new_hook = str_replace($prefix . '_', '', $match);
$templates[$new_hook] = array(
'function' => $match,
'arguments' => $info['arguments'],
);
}
}
}
if (function_exists($prefix . '_' . $hook)) {
$templates[$hook] = array(
'function' => $prefix . '_' . $hook,
);
// Ensure that the pattern is maintained from base themes to its sub-themes.
// Each sub-theme will have their functions scanned so the pattern must be
// held for subsequent runs.
if (isset($info['pattern'])) {
$templates[$hook]['pattern'] = $info['pattern'];
