Is there a save_post hook for custom post types?

1. the hook is the same save_post just make sure its your post type ex:

   add_action('save_post','save_post_callback');
   function save_post_callback($post_id){
       global $post; 
       if ($post->post_type != 'MY_CUSTOM_POST_TYPE_NAME'){
           return;
       }
       //if you get here then it's your post type so do your thing....
   }

2. New solution, as of WP 3.7: save_post_{$post_type}

   add_action( 'save_post_my_post_type', 'wpse63478_save' );
   function wpse63478_save() {
       //save stuff
   }
   

   See the note on the codex page

3. call function my_func() whene publish(save) special post type

   add_action('save_post_[name_of_post_type]', ' my_func');
   

   call function my_func() whene publish(save) all post type (post, page, product, …)

   add_action('save_post', 'my_func');
