NAME

       vga_drawline - draw a line on the screen

SYNOPSIS

       #include <vga.h>

       int vga_drawline(int x1, int y1, int x2, int y2);

DESCRIPTION

       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).
