Function Documentation

EAPI Evas_List* evas_list_promote_list (Evas_List * list, Evas_List * move_list)

Moves the specified data to the head of the list.

Move a specified member to the head of the list

Parameters:

list The list handle to move inside
move_list The list node which is to be moved

Returns:

A new list handle to replace the old one

Calling this function takes the list node move_list and moves it to the front of the list.

Example:

 extern Evas_List *list;
 Evas_List *l;
 extern void *my_data;

 for (l = list; l; l= l->next)
   {
     if (l->data == my_data)
       {
         list = evas_list_promote_list(list, l);
         break;
       }
   }
