windows - How to get the screen auto-rotate's status?

Question

How to get the screen auto-rotate's status (disable or enable) by Regetry or ACPI in windows8?

I need to disable screen auto-rotate, and I will use winkey + O to change the screen auto-rotate control.

Does anyone have similar experiences?

Below maybe helpful if you want to change auto-rotate status:

//C++
typedef BOOL (WINAPI* SETAUTOROTATION)(BOOL bEnable);

SETAUTOROTATION SetAutoRotation = (SETAUTOROTATION)GetProcAddress(GetModuleHandle(TEXT("user32.dll")), (LPCSTR)2507);
if(SetAutoRotation != NULL)
{
  SetAutoRotation(TRUE);
}

or

//C#
[DllImport("user32.dll", EntryPoint = "#2507")]
extern static bool SetAutoRotation(bool bEnable);

SetAutoRotation(true);
