vga_getpixel — get a pixels value from the screen
int vga_getpixel(int x, int y);
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.

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.
