post_handler - Post-handler
The post-handler allows performing an action after reacting on the event. Post-handlers can be defined as function or expression actions in the context defined by the action. The result from the reaction ( YES in case of an error) is passed to the post-handler as parameter. The post-handler should return this value to the system when terminating unless there is a good reason to ignore the signaled error.
