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


       #include <vga.h>

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


       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).

       This  manual  page  was edited by Michael Weller <>. 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

       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
