vga_getpixel(3)               Svgalib User Manual              vga_getpixel(3)

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.

       It is very likely that both are at least to some extent are due to Harm
