NAME

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

SYNOPSIS

10       #include <vga.h>
11
12       int vga_screenoff(void);
13       int vga_screenon(void);

DESCRIPTION

17       The functions turn the generation of the video signal  on  or  off.  On
18       some video boards, SVGA memory access is faster when no video signal is
19       generated. On the other hand, not all boards allow to  disable  it  (at
20       least not in all modes).
21
22       The  functions always return 0 (on which you should probably not really
23       rely).
