Detailed Description

This union represents a chain control block.

This is used to manage a chain. A chain consists of a doubly linked list of zero or more nodes.

Note

This implementation does not require special checks for manipulating the first and last elements on the chain. To accomplish this the Chain_Control structure is treated as two overlapping Chain_Node structures.
