do_circle

Calculates all the points in a circle.

Description

void do_circle(BITMAP *bmp, int x, int y, int radius, int d, void (*proc)(BITMAP *bmp, int x, int y, int d));
Calculates all the points in a circle around point (x, y) with radius r, calling the supplied function for each one. This will be passed a copy of the bmp parameter, the x and y position, and a copy of the d parameter, so it is suitable for use with putpixel(). Example:
      void draw_explosion_ring(BITMAP *bmp, int x, int y, int d)
      {
	 ...
      }

do_circle(screen, SCREEN_W/2, SCREEN_H/2, SCREEN_H/16, flame_color, draw_explosion_ring);
