Hi,
 
I try to use the function SDGetDeviceHandle (http://msdn2.microsoft.com/en-us/library/ms920364.asp). this is the description :
 SD_DEVICE_HANDLE SDGetDeviceHandle(
  DWORD InitContext,
  PWCHAR* ppRegPath
);
 
Parameters :  
InitContext  
[in] Device context passed into the XXX_Init entry point of a client device driver.  
 
But I don't understand what is the InitContext. I want to retrieve an handle to the sd bus device.
 
Thanks for your help
 
Best regards
 
Steve
