How do i know the current post type when on post.php in admin?

Im trying to do something with an admin_init hook if - and only if - the user is editing a post (post.php) with post type "event". My problem is that, even though wordpress points to a global variable calls $post_type. if i do:

global $post_type;
var_dump($post_type);

It returns NULL.

but if I do this:

global $pagenow;
var_dump($pagenow);

it returns my current page. i.e. "post.php".

I looked into this function $screen = get_current_screen(); but thats not declared until after the admin_init hooks has run, and then its to late.

So my question is, how do I, by the time admin_init is run, find out what post type the current post being edited is. if the url is post.php?post=81action=edit then, how do I know what post type postid=81 is?

Thanks Malthe

get_current_screen()->post_type holds post type slug. Or $_REQUEST['post_type']. Note that for standard pages/posts post_type might not be set.

I am going to expand on MiCc83's answer. There are a few things that don't follow the OP's original questions but overall it's a great solution. For example, it would not work with a post_type event because you are checking the post_type as 'post' in the answer.

add_action( 'admin_init', 'do_something_152677' );
function do_something_152677 () {
    // Global object containing current admin page
    global $pagenow;

    // If current page is post.php and post isset than query for its post type 
    if ( 'post.php' === $pagenow && isset($_GET['post']) ){
        $post_id = $_GET['post'];

        // Do something with $post_id. For example, you can get the full post object:
        $post = get_post($post_id);

    }
}

The condition 'post' === get_post_type( $_GET['post'] ) in the previous answer would prevent this from working on a post type 'event'. You would need to check for post type 'event' instead of 'post'.

        // Do something
    }
}
