  67  * The ndis_kspin_lock type is called KSPIN_LOCK in MS-Windows.

  69  *      typedef ULONG_PTR KSPIN_LOCK;
  70  *
  71  * From basetsd.h (SDK, Feb. 2003):
  72  *      typedef [public] unsigned __int3264 ULONG_PTR, *PULONG_PTR;
  73  *      typedef unsigned __int64 ULONG_PTR, *PULONG_PTR;
  74  *      typedef _W64 unsigned long ULONG_PTR, *PULONG_PTR;
  75  *
  76  * The keyword __int3264 specifies an integral type that has the following
  77  * properties:
  78  *      + It is 32-bit on 32-bit platforms
  79  *      + It is 64-bit on 64-bit platforms
  80  *      + It is 32-bit on the wire for backward compatibility.
  81  *        It gets truncated on the sending side and extended appropriately
  82  *        (signed or unsigned) on the receiving side.
  83  *
  84  * Thus register_t seems the proper mapping onto FreeBSD for spin locks.
