46 /** The key that lead us to this one for DFS/BFS. */

61 * initcolour - Clear the key graph ready for use.
62 * @parent: Do we want to clear the parent pointers too?
64 * Clears the parent and colour information on all elements in the key
67 void initcolour(bool parent);
70 * findpath - Given 2 keys finds a path between them.
71 * @have: The key we have.
72 * @want: The key we want to get to.
74 * This does a breadth first search on the key tree, starting with the
75 * key we have. It returns as soon as a path is found or when we run out
76 * of keys; whichever comes sooner.

82 * dofindpath - Given 2 keys displays a path between them.
83 * @have: The key we have.
84 * @want: The key we want to get to.
85 * @html: Should we output in html.
86 * @count: How many paths we should look for at most.
88 * This does a breadth first search on the key tree, starting with the
