Senff on "Call function on multiple actions"

I'm writing some function that needs to be executed every time something changes in the list of posts. So, whenever:
- a new post is published
- an existing post is edited
- an existing post is deleted

I was thinking to do it like this:

add_action('publish_post', myfunction());
add_action('post_updated', myfunction());
add_action('deleted_post', myfunction());

I think the second one is not even necessary (it's executed with publish_post anyways) but is there a better way to do this, instead of calling the function in various situations?

Is it possible to do something like this (not literally, but structure-wise)?

add_action( ('publish_post' OR 'post_updated' OR 'deleted_post') , myfunction() );
