int somefunc (const char *path, struct stat *statbuf, int flag)
{
	if (flag & FTW_F) {
	    /* add `path' to tree */
        }
        return 0;
}

....  ftw ("/start", somefunc, 60);

Note that the pointers to the GtkCTree or whatever have to be globals
or similar, because the designers of ftw(3) had not heard of the idea
of a passed-in user-pointer :(

The order will match that of scandir - you can't change this other
than by sorting the tree or some intermediate data structure after the
fact.
