Respond to node updating.

This is a hook used by node modules. It is called to allow the module to take action when an edited node is being updated in the database by, for example, updating information in related tables.


$node: The node being updated.

Return value


To take action when nodes of any type are updated (not just nodes of the type(s) defined by this module), use hook_nodeapi() instead.

For a detailed usage example, see node_example.module.
