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).
