vga_drawpixel(3)	       Svgalib User Manual		vga_drawpixel(3)

NAME
     vga_drawpixel - draw a pixel on the screen

SYNOPSIS
     #include <vga.h>

     int vga_drawpixel(int x, int y);

DESCRIPTION
     Read a pixels value from the screen. This function is very inefficient, you
     should  consider doing direct screen access instead or use vga_drawscanseg-
     ment(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).

AUTHOR
     This  manual  page  was  edited  by Michael Weller <eowmob@exp-math.uni-es-
     sen.de>. The 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 Harm
     Hanemaayer <H.Hanemaayer@inter.nl.net>.

     Occasionally this might be wrong. I hereby asked to be excused by the orig-
     inal author and will happily accept any additions or  corrections	to  this
     first version of the svgalib manual.
