vga_drawline3
Draw a line on the screen
Usage
#include <vga.h>
int vga_drawline(int x1, int y1, int x2, int y2);
Overview
draws a line from (x1, y1) to (x2, y2) on the screen. If you exchange start and end of the line you should not expect the exactly identical set of pixel be covered by the line.
This function is very inefficient as is does a bunch of vga_drawpixel(3) calls, you should consider using gl_line(3) which is very efficient, or doing direct screen access instead or use vga_drawscansegment(3) to handle more than one pixel.
The color drawn is set with vga_setcolor(3) or vga_setrgbcolor(3) resp.
The function always returns 0 (on which you should probably not really rely).
