NAME
       list - list routines

SYNOPSIS
	   #include <inn/list.h>

	   struct node {
	       struct node *succ;
	       struct node *pred;
	   };

	   struct list {
	       struct node *head;
	       struct node *tail;
	       struct node *tailpred;
	   };

	   void	list_new(struct	list *list);

	   struct node *list_addhead(struct list *list,	struct node *node);

	   struct node *list_addtail(struct list *list,	struct node *node);

	   struct node *list_head(struct list *list);

	   struct node *list_tail(struct list *list);

	   struct node *list_succ(struct node *node);

	   struct node *list_pred(struct node *node);

	   struct node *list_remhead(struct list *list);

	   struct node *list_remtail(struct list *list);

	   struct node *list_remove(struct node	*node);

	   struct node *list_insert(struct list	*list, struct node *node, struct node *pred);

	   bool	list_isempty(struct list *list);

DESCRIPTION
       list_new	initialises the	list header list so as to create an empty
       list.

       list_addhead adds node to the head of list, returning the node just
       added.

       list_addtail adds node to the tail of list, returning the node just
       added.

       list_head returns a pointer to the the node at the head of list or NULL
       if the list is empty.

       list_tail returns a pointer to the the node at the tail of list or NULL
       if the list is empty.

       list_succ returns the next (successor) node on the list after node or
       NULL if node was	the final node.

       list_pred returns the previous (predecessor) node on the	list before
       node or NULL if node was	the first node.

       list_remhead removes the	first node from	list and returns it to the
       caller. If the list is empty NULL is returned.

       list_remtail removes the	last node from list and	returns	it to the
       caller. If the list is empty NULL is returned.

       list_remove removes node	from the list it is on and returns it to the
       caller.

       list_insert inserts node	onto list after	the node pred. If pred is NULL
       then node is added to the head of list.
