I’m hoping for a simple way to tell/find/echo what the available arguments are available for use at a given hook.

For example —

function example_function($something){

    //do stuff with $something
    return $something;

}
add_action('some_hook','example_function');

In the above case, is there a quick way to tell what $something is (if there is one at all), or if there are multiple $somethings / arguments I have available to use at that point?
