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).

It is very likely that both are at least to some extent are due to Harm

Occasionally this might be wrong. I hereby asked to be excused by the
