do_line(3)			 Allegro manual 		      do_line(3)

NAME
     do_line  - Calculates all the points along a line. Allegro game programming
     library.

SYNOPSIS
     #include <allegro.h>

     void do_line(BITMAP *bmp, int x1, y1, x2, y2, int	d,  void  (*proc)(BITMAP
     *bmp, int x, int y, int d));

DESCRIPTION
     Calculates  all  the  points  along a line from point (x1, y1) to (x2, y2),
     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_dust_particle(BITMAP *bmp, int x, int y, int d)
	{
	   ...
	}

	   do_line(screen, 0, 0, SCREEN_W-1, SCREEN_H-2,
		   dust_strength, draw_dust_particle);
