int advance (void)
 Move forward by one element in the set. Returns 0 when all the items in the queue have been seen, else 1. More...

int first (void)
 Move to the first element in the queue. Returns 0 if the queue is empty, else 1. More...

int done (void) const
 Returns 1 when all items have been seen, else 0. More...
