vga_setdisplaystart3
Set the display start address
Usage
#include <vga.h>
void vga_setdisplaystart(int a);
Overview
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).
Releases
