	A registry for chain iterators. More...

Macros
#define	CHAIN_INITIALIZER_EMPTY(name)    { { { &(name).Tail.Node, NULL }, &(name).Head.Node } }
	Chain initializer for an empty chain with designator name.
#define	CHAIN_INITIALIZER_ONE_NODE(node)    { { { (node), NULL }, (node) } }
	Chain initializer for a chain with one node.
#define	CHAIN_NODE_INITIALIZER_ONE_NODE_CHAIN(chain)    { &(chain)->Tail.Node, &(chain)->Head.Node }
	Chain node initializer for a chain containing exactly this node.
#define	CHAIN_DEFINE_EMPTY(name)    Chain_Control name = CHAIN_INITIALIZER_EMPTY(name)
	Chain definition for an empty chain with designator name.
#define	CHAIN_ITERATOR_REGISTRY_INITIALIZER(name)    { CHAIN_INITIALIZER_EMPTY( name.Iterators ) }
	Chain iterator registry initializer for static initialization.

Typedefs
typedef bool(*	Chain_Node_order) (const void *key, const Chain_Node *left, const Chain_Node *right)
	Chain node order.

Enumerations
enum	Chain_Iterator_direction { CHAIN_ITERATOR_FORWARD , CHAIN_ITERATOR_BACKWARD }
	The chain iterator direction. More...

Functions
void	_Chain_Initialize (Chain_Control *the_chain, void *starting_address, size_t number_nodes, size_t node_size)
	Initializes a chain header.
size_t	_Chain_Node_count_unprotected (const Chain_Control *chain)
	Returns the node count of the chain.
