What doesn't work with these functions? Posting some code that
demonstrates your problem would help a lot...

To fade the screen background (color 0) from black to white, try
something like:

   int i;
   RGB c;

   for (i=0; i<64; i++) {
      c.r = c.g = c.b = i;
      vsync();
      set_color(0, &c);
   }

If you just want to fade in the entire screen, though, try using the
fade_in() function, which does all the work for you (look at the demo
game for an example of how it is used).
