Gets a book menu link by its menu link ID.

$mlid: The menu link ID of the menu item.
A menu link, with the link translated for rendering and data added from the {book} table. FALSE if there is an error.
function book_link_load($mlid) {
if ($item = db_query("SELECT * FROM {menu_links} ml INNER JOIN {book} b ON b.mlid = ml.mlid LEFT JOIN {menu_router} m ON m.path = ml.router_path WHERE ml.mlid = :mlid", array(
':mlid' => $mlid,
))
->fetchAssoc()) {
_menu_link_translate($item);
return $item;
}
return FALSE;
