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).

AUTHOR

       This  manual  page  was  edited by Michael Weller <eowmob@exp-math.uni-
       essen.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.
