remove_action()WP 1.2.0

Removes a function from a specified action hook.

This can be used to remove default functions attached to a specific action hook and possibly replace them with a substitute.

To remove a hook, the $callback and $priority arguments must match when the hook was added. This goes for both filters and actions. No warning will be given on removal failure.
