vga_drawline(3)		      Svgalib User Manual	       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_draw‐
       pixel(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).
