Programmer - C++ TCL (tree container library): How to traverse a tree from a node straight to root

Programmer Question

I am using this library to hold information about tree structure:

http://www.datasoftsolutions.net/tree_container_library/overview.php

Here is simplified version of my C++ code:

#include "tcl/sequential_tree.h"

// Node has some data which is not important now

typedef sequential_tree<Node> gametree_t;
typedef sequential_tree<Node>::iterator gametree_iter;

int main() {
    gametree_t gametree;
    gametree_iter gametree_it;

    gametree_it = gametree.insert(Node(0));
    gametree_it->insert(Node(1));
    gametree_it->insert(Node(2));

    gametree_it = gametree_it->insert(Node(3));
    gametree_it->insert(Node(4));

    gametree_it = gametree_it->insert(Node(5));
    gametree_it->insert(Node(6));

    return 1;
}

The tree looks like this

0
|_ 1
|_ 2
|_ 3
  |_4
  |_5
    |_6

I am trying to make a function which given the Node(6) will traverse all the nodes leading to root i.e 6,5,3,0. This is my first project in C++ and I have trouble understanding pointers. Probably it is a few lines of C++ but I'm trying to do this for a couple of hours with no success. Any help will be appreciated.

something like this works but it must work with many levels not only with 4:

gametree_it->get()->get_value();
gametree_it->parent()->get()->get_value();
gametree_it->parent()->parent()->get()->get_value();
gametree_it->parent()->parent()->parent()->get()->get_value();
