That's how I'd do it:

#define max_x 25
#define max_y 25

defPt *View;

main ()
   {
      View = (defPt *) malloc (sizeof (defPt) * max_x * max_y);

      // referencing

      *(View + x + y * max_x) = 25;
      some_int = (View + x + y * max_x)->sx;
   }

You'll get warnings saying that you are converting int to pointer whithout
a cast. Just ignore them. It works. (Unless someone else knows something
else about it that I don't).
