Deregister custom post types

Anyone know of a way to deregister custom post types?

Is there an equivalent to register_post_type()?

As of WordPress 4.5 there is function to do that, unregister_post_type. Example:-

function delete_post_type(){
    unregister_post_type( 'blocks' );
}
add_action('init','delete_post_type');
