function shortcut_admin_add_link

shortcut_admin_add_link($shortcut_link, &$shortcut_set, $limit = NULL)

Adds a link to the end of a shortcut set, keeping within a prescribed limit.

Parameters

$link: An array representing a shortcut link.

$shortcut_set: An object representing the shortcut set which the link will be added to. The links in the shortcut set will be re-weighted so that the new link is at the end, and some existing links may be disabled (if the $limit parameter is provided).

$limit: (optional) The maximum number of links that are allowed to be enabled for this shortcut set. If provided, existing links at the end of the list that exceed the limit will be automatically disabled. If not provided, no limit will be enforced.
