NAME
       vga_setdisplaystart - set the display start address

SYNOPSIS
       #include <vga.h>

       void vga_setdisplaystart(int a);

DESCRIPTION
       Set the display start address to a, where the address is the number of
       pixels offset from the start of video memory, except for
       hicolor/truecolor modes, which use a unit of 1 byte. Can be used for
       page-flipping and virtual desktop scrolling. May not work properly for
       16 color modes.

       You should ensure that the memory displayed is actually available on
       the SVGA card (query memory size with vga_modeinfo(3)) and ensure that
       it is saved by svgalib during console switches with
       vga_claimvideomemory(3).

       You may only set the bits of the display start address returned by
       vga_modeinfo(3).
