Inform modules that a menu link has been deleted.
This hook is used to notify modules that menu items have been deleted. Contributed modules may use the information to perform actions based on the information entered into the menu system.
$link: Associative array defining a menu link as passed into menu_link_save().
Note: this list is generated by pattern matching, so it may include some functions that are not actually implementations of this hook.
function hook_menu_link_delete($link) {
// Delete the record from our table.
db_delete('menu_example')
->condition('mlid', $link['mlid'])
->execute();
}
