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.
