_LUID structure

An LUID is a 64-bit value guaranteed to be unique only on the system on which it was generated. The uniqueness of a locally unique identifier (LUID) is guaranteed only until the system is restarted.

Applications must use functions and structures to manipulate LUID values.

typedef struct _LUID {
  DWORD LowPart;
  LONG  HighPart;
} LUID, *PLUID;
