| 17 | * Close a list for sequential access. | |
| 18 | * The sequential functions access the list in a slightly different way. | |
| 19 | * CurPtr points to their idea of the current node in the list and they | |
| 20 | * access the list based on it. Because the list is circular, Lst_Next | |
| 21 | * and Lst_Prev will go around the list forever. Lst_IsAtEnd must be | |
| 22 | * used to determine when to stop. | |
