Detailed Description

Common base for devices.

Note

oddly similar to _DEVOBJ_EXTENSION but DeviceObjectExtension is not the same as DeviceExtension!? MS has a class called CDeviceObject in MSJ ??

Member Function Documentation

AttachToDeviceStack()

CKeDeviceObject* GrayKernel::CKeDeviceExt::AttachToDeviceStack ( PDEVICE_OBJECT  pDeviceObjectAttach )

inline

Note

IoAttachDeviceToDeviceStackSafe() would solve the theoretic race condition here. Must call IoDetachDevice() later

DeleteDevice()

void GrayKernel::CKeDeviceExt::DeleteDevice ( )

inline

Flag_Init_Clear()

void GrayKernel::CKeDeviceExt::Flag_Init_Clear ( )

inline

We are finished with the Init.

get_DeviceObject()

CKeDeviceObject* GrayKernel::CKeDeviceExt::get_DeviceObject ( ) const

inline

GetDeviceExt()

static CKeDeviceExt* GrayKernel::CKeDeviceExt::GetDeviceExt ( PDEVICE_OBJECT  pDeviceObj )

InitDeviceExt()

void GrayKernel::CKeDeviceExt::InitDeviceExt ( USHORT  uSize, PDEVICE_OBJECT  pDeviceObj  )

inline

IsDeviceValid() [1/2]

bool GrayKernel::CKeDeviceExt::IsDeviceValid ( ) const

inline

IsDeviceValid() [2/2]

bool GrayKernel::CKeDeviceExt::IsDeviceValid ( IN PDEVICE_OBJECT  _pDeviceObject ) const

inline
