vga_screenoff(3)	      Svgalib User Manual	      vga_screenoff(3)

NAME
       vga_screenoff, vga_screenon - turn generation of	the video signal on or
       off

SYNOPSIS
       #include	<vga.h>

       int vga_screenoff(void);
       int vga_screenon(void);

DESCRIPTION
       The functions turn the generation of the	video signal  on  or  off.  On
       some video boards, SVGA memory access is	faster when no video signal is
       generated. On the other hand, not all boards allow to  disable  it  (at
       least not in all	modes).

       The  functions always return 0 (on which	you should probably not	really
       rely).

       vga_clear(3),

AUTHOR
       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.
