WINBIO_SUPPORTED_ALGORITHMS structure (winbio_ioctl.h)

The WINBIO_SUPPORTED_ALGORITHMS structure is the OUT payload for IOCTL_BIOMETRIC_GET_SUPPORTED_ALGORITHMS.

Syntax

typedef struct _WINBIO_SUPPORTED_ALGORITHMS {
  DWORD       PayloadSize;
  HRESULT     WinBioHresult;
  DWORD       NumberOfAlgorithms;
  WINBIO_DATA AlgorithmData;
} WINBIO_SUPPORTED_ALGORITHMS, *PWINBIO_SUPPORTED_ALGORITHMS;

Members

PayloadSize

Specifies the total size of the payload, which includes the fixed length structure and any variable data at the end.

WinBioHresult

NumberOfAlgorithms

Specifies the number of algorithms in the data block.

AlgorithmData

Specifies a structure of type WINBIO_DATA that contains NULL-terminated UTF-8 OID strings that represent the algorithms supported by the device.
