Determine if locking should be disabled for a given node (e.g. by checking its type or other properties).

This hook is called from content_lock_form_alter() before it determines that it is altering a node modification form. Thus, some of this hook's paramesters are the same parameters that would be passed to hook_form_alter().

An implementation of this hook can be used to make the ability to lock a node conditional on an arbitrary aspect of the node.

Parameters

$node: The node for which a lock might be created. This parameter may be NULL in the case that the form is for something other than a node.

$form_id: The form_id for the node's edit form.

$form: The form for the node's edit form.

$form_state: The form_state for the node's edit form.

Return value

FALSE to indicate that locking is allowed or TRUE to prevent this node from being locked.
