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