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

|
|
.SH SYNOPSIS
|

|
|
|
||
|
|
.B "#include <vga.h>"
|

|
.SH 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).
