WINBIO_BIR_DATA structure

  • Article

The WINBIO_BIR_DATA structure specifies the size, in bytes, and the offset of a block of biometric information. This structure is used by the WINBIO_BIR structure to specify where the various parts of a biometric information record are located.

Syntax

typedef struct _WINBIO_BIR_DATA {
  ULONG Size;
  ULONG Offset;
} WINBIO_BIR_DATA;

Members

Size

Size, in bytes, of the biometric information.

Offset

Offset, in bytes from the beginning of the WINBIO_BIR structure, of the biometric information.

Remarks

The use of offsets rather than pointers allows for easy serialization of the BIR and for less complicated translation between 32 and 64-bit environments or between user and kernel mode.
