function menu_get_local_tasks in Drupal 4

Same name and namespace in other branches

1. 5 includes/menu.inc \menu_get_local_tasks()

Return the local task tree.

Unlike the rest of the menu structure, the local task tree cannot be cached nor determined too early in the page request, because the user's current location may be changed by a menu_set_location() call, and the tasks shown (just as the breadcrumb trail) need to reflect the changed location.
