The IOCTL_BIOMETRIC_CAPTURE_DATA IOCTL uses the WINBIO_CAPTURE_PARAMETERS structure as input.

Syntax


typedef struct _WINBIO_CAPTURE_PARAMETERS {
  DWORD                    PayloadSize;
  WINBIO_BIR_PURPOSE       Purpose;
  WINBIO_REGISTERED_FORMAT Format;
  WINBIO_UUID              VendorFormat;
  WINBIO_BIR_DATA_FLAGS    Flags;
} WINBIO_CAPTURE_PARAMETERS, *PWINBIO_CAPTURE_PARAMETERS;

Members

The total size of the payload.

Purpose

Specifies a WINBIO_BIR_PURPOSE reason for the data collection. Some sensors will go into a different mode depending on the reason for the data capture.

Format
