reset permalink for all custom type posts

Hi,

I want to delete a permalink for all posts of my CPT. It should just work like default when u delete permalink and let WP generate new one.

My client duplicated posts, and forgot to change permalink, now there is about 150 products with wrong permalink.

The function will be runned only once.

I want something like this:

function reset_permalinks(){
  $posts = get_all_cpt_posts('cpt_name');

 foreach ($posts as $post) {

    reset_permalink($post);

  }

}

What is the wp function to reset permalink? I mean, what function WP use when u set permalink to empty and save a post – then its generated – i need this function 🙂
