   Example migrated from Codex:

   add_action( 'parse_request', 'change_post_per_page_wpent' );
   
   function change_post_per_page_wpent( $query ) {
       if (  'my_cpt' == $query->query_vars['post_type'] ) {
           $query->query_vars[ 'posts_per_page' ] = 3;
       }
       
       return $query;
   }

   • Being an action hook, it does not expect a return value.
