NAME
do_circle - Calculates all the points in a circle. Allegro game programming library. SYNOPSIS
#include <allegro.h> void do_circle(BITMAP *bmp, int x, int y, int radius, int d, void (*proc)(BITMAP *bmp, int x, int y, int d)); DESCRIPTION
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().
