EAPI Evas_List* evas_list_last (const Evas_List * list)
Get the last list node in the list. Parameters:
- list The list to get the last list node from
Returns:
- The last list node in the list list
This function will return the last list node in the list (or NULL if the list is empty).
NB: This is a order-1 operation (it takes the same short time regardless of the length of the list).
Example:
extern Evas_List *list;
Evas_List *last, *l;
last = evas_list_last(list);
printf(‘The list in reverse:);
for (l = last; l; l = l->prev)
{
printf(‘%p, l->data);
}

EAPI Evas_List* evas_list_next (const Evas_List * list)
Get the next list node after the specified list node. Parameters:
- list The list node to get the next list node from
Returns:
- The next list node, or NULL if no next list node exists
This function returns the next list node after the current one. It is equivalent to list->next.
Example:
extern Evas_List *list;
Evas_List *l;
printf(‘The list:);
for (l = list; l; l = evas_list_next(l))
{
printf(‘%p, l->data);
}

EAPI Evas_List* evas_list_prev (const Evas_List * list)
Get the previous list node before the specified list node. Parameters:
- list The list node to get the previous list node from
Returns:
- The previous list node, or NULL if no previous list node exists
This function returns the previous list node before the current one. It is equivalent to list->prev.
Example:
extern Evas_List *list;
Evas_List *last, *l;
last = evas_list_last(list);
printf(‘The list in reverse:);
for (l = last; l; l = evas_list_prev(l))
{
printf(‘%p, l->data);
}
