NDIS_PROTOCOL_BLOCK的定义

http://blog.csdn.net/rhettxie/archive/2006/03/07/618083.aspx

NDIS_PROTOCOL_BLOCK 结构的完整定义我翻遍了DDK都没找到，翻windows2000源代码也没找到。google到驱动开发网上一篇讲封包过滤技术的文章，里面给出了NDIS_PROTOCOL_BLOCK 的定义。我打印出来对照的一个NDIS protocol hook的代码看，总感觉这个结构的定义有问题。不爽了好几天。今天终于google到正确的定义，放这存着：

Q: Where can I get the definition of NDIS_PROTOCOL_BLOCK structure? Does it depend of Windows version or NDIS version?

A: _NDIS_PROTOCOL_BLOCK structure definition depends of Windows and NDIS versions and it's just partially documented by

Microsoft. Some it's definitions can be found in ndis.h. An example, for Windows XP NDIS_PROTOCOL_BLOCK defined as the

following:

struct _NDIS_PROTOCOL_BLOCK
{
  _NDIS_OPEN_BLOCK*    OpenQueue;
  _REFERENCE     Ref;
  _KEVENT*     DeregEvent;
  _NDIS_PROTOCOL_BLOCK*   NextProtocol;
  _NDIS50_PROTOCOL_CHARACTERISTICS  ProtocolCharacteristics;
  _WORK_QUEUE_ITEM    WorkItem;
  _KMUTANT     Mutex;
  DWORD     MutexOwner;
  _UNICODE_STRING*    BindDeviceName;
  _UNICODE_STRING*    RootDeviceName;
  _NDIS_M_DRIVER_BLOCK*   AssociatedMiniDriver;
  _NDIS_MINIPORT_BLOCK*   BindingAdapter;
};
But in ndis.h for Windows ME you can find the following definition:

//-----------------驱动开发网上给的是这个，这个已经过时了---------------------

struct _NDIS_PROTOCOL_BLOCK
{
  PNDIS_OPEN_BLOCK       OpenQueue;  // queue of opens for this protocol
  REFERENCE        Ref;  // contains spinlock for OpenQueue
  UINT         Length; // of this NDIS_PROTOCOL_BLOCK struct
  NDIS50_PROTOCOL_CHARACTERISTICS   ProtocolCharacteristics;// handler addresses struct
  _NDIS_PROTOCOL_BLOCK *      NextProtocol; // Link to next   
  ULONG        MaxPatternSize;
#if defined(NDIS_WRAPPER)
  //
  // Protocol filters
  //
  struct    _NDIS_PROTOCOL_FILTER * ProtocolFilter[NdisMediumMax+1];
  WORK_QUEUE_ITEM       WorkItem; // Used during NdisRegisterProtocol to
      // notify protocols of existing drivers.
  KMUTEX        Mutex;  // For serialization of Bind/Unbind requests
  PKEVENT        DeregEvent; // Used by NdisDeregisterProtocol
#endif
};
As you can see this structure definition depends of NDIS_PROTOCOL_CHARACTERISTICS definition, which is NDIS version

dependent. The Windows version dependence does not need any comments.

也给出NDIS_OPEN_BLOCK定义，这个是在xp ddk的ndis.h里翻出来的：
