Function Documentation
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:\n"); for (l = last; l; l = l->prev) { printf("%p\n", l->data); }

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:\n"); for (l = list; l; l = evas_list_next(l)) { printf("%p\n", l->data); }

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:\n"); for (l = last; l; l = evas_list_prev(l)) { printf("%p\n", l->data); }
