function hook_menu_contextual_links_alter in Drupal 7

Alter contextual links before they are rendered.

This hook is invoked by menu_contextual_links(). The system-determined contextual links are passed in by reference. Additional links may be added or existing links can be altered.

Each contextual link must at least contain:

• title: The localized title of the link.
• href: The system path to link to.
• localized_options: An array of options to pass to url().

Parameters

$links: An associative array containing contextual links for the given $root_path, as described above. The array keys are used to build CSS class names for contextual links and must therefore be unique for each set of contextual links.

$router_item: The menu router item belonging to the $root_path being requested.

$root_path: The (parent) path that has been requested to build contextual links for. This is a normalized path, which means that an originally passed path of 'node/123' became 'node/%'.
