msdn上没有类驱动相关的函数介绍，请问哪里有？

ClassInitialize
ClassClaimDevice
ClassCreateDeviceObject
ClassUpdateInformationInRegistry
这一种形式的函数我在msdn6.0和msdn2003里都找不到说明，而win2000DDK的src\\storage\\class目录下的例子都用到了这些函数，请问哪里能找到这些相关的函数说明啊？
  另外这些函数是不是己经不使用了？那该怎么替代这些？

System Header Files for Storage Drivers
The system-supplied storage drivers include the header file scsi.h, which contains SCSI-compliant definitions for CDBs and other structures used by most SCSI-compliant drivers. This header file includes srb.h, which defines the interfaces provided by the system-supplied port drivers to next-lower storage class and filter drivers.

Operating system-independent SCSI miniport drivers, which can be designed to run both with all platforms of NT-based operating systems and with x86-only Microsoft Windows systems, include the system-supplied header files miniport.h and scsi.h, which includes srb.h.

Tape miniclass drivers include minitape.h.

Medium changer miniclass drivers include mcd.h.

System-supplied class and filter drivers also can include the header file classpnp.h, so they can call the ClassXxx routines provided by classpnp.c. The DDK for Windows? 2000 and later operating systems provides classpnp.h and classpnp.c as sample source code. However, classpnp.c should not be considered a system-supplied library for all future storage class drivers. Both classpnp.h and classpnp.c are subject to change without notice.

就在那个文件里，就它自己定义的函数，别处当然没法找
