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