vga_drawline(3)

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 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).

It is very likely that both are at least to some extend are due to Harm Hanemaayer <H.Hanemaayer@inter.nl.net>. Occasionally this might be wrong.
