vga_drawline (3)
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).

exact source of the referenced function as well as of the original documentation is
unknown.
It is very likely that both are at least to some extent are due to
