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).
