vga_setdisplaystart(3)	      Svgalib User Manual	vga_setdisplaystart(3)

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/true-
       color  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_claimvideomem-
       ory(3).

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

       This manual page	was edited by Michael Weller  <eowmob@exp-math.uni-es-
       sen.de>.	 The exact source of the referenced function as	well as	of the
       original	documentation is unknown.

       It is very likely that both are at least	to some	extent are due to Harm
       Hanemaayer <H.Hanemaayer@inter.nl.net>.

       Occasionally  this  might be wrong. I hereby asked to be	excused	by the
       original	author and will	happily	accept any additions or	corrections to
       this first version of the svgalib manual.
