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).
