So I do the following in pfiv.C:

if (DoClean)
        result = pfdCleanTree(result, cleanNode);

"cleanNode" is my function which will decide about node deletion and is
as follows:

int cleanNode(pfuTraverser *trav)
{
        pfGroup *currGrp = (pfGroup *) trav->node;

        if (currGrp == doNotDeleteNode)
            return FALSE;
        else return TRUE;
}

The above function fails because "trav->node" is NULL. Why doesn't "trav"
have a proper node address?

Am I not using it properly? Do I need to declare a separate traverser
and call pfuInitTraverser on it in pfiv.C?

Please help....
