Sleep Display
-
Hi,
I noticed steve added the nice feature to sleep the display via a hot
corner, but is there a way for us devs to hook into it? I am currently using
a pmset hack which i would prefer to use a cleaner method -

Undocumented, use at your own risk, etc. It ends up involving more
IOKit than Cocoa, as it turns out.
#include <CoreFoundation/CoreFoundation.h>
#include <IOKit/IOKitLib.h>
int dimDisplayNow(void) {
io_registry_entry_t r =
IORegistryEntryFromPath(kIOMasterPortDefault, "IOService:/IOResources/
IODisplayWrangler");
if(!r) return 1;
int err = IORegistryEntrySetCFProperty(r, CFSTR("IORequestIdle"),
kCFBooleanTrue);
IOObjectRelease(r);
return err;

Hi,
How far back is this compatible? is it only 10.5?

Hi. I've tryed this code and it works. The problem is that with some
machines it causes a kernel panic. They are PPC machines. Isn't this
code compatible?

You should file a bug report with Apple (bugreport.apple.com) then —
code outside the kernel is never supposed to be able to cause a panic.
Make sure to include your source code if possible.
