vga_setdisplaystart (3)
set the display start address
SYNOPSIS
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).
