NAME
       vga_getpixel - get a pixels value from the screen

SYNOPSIS
       #include <vga.h>

       int vga_getpixel(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_getscansegment(3) to handle more than one pixel.

       This manual page was edited by Michael Weller <eowmob@exp-math.uni-essen.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 original author and will happily accept any additions or  corrections
       to this first version of the svgalib manual.
