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. HISTORY
