Biometric Error Codes

Many of the structures that are used for output data in the WBDI IOCTLs contain a WinBioHresult member of type HRESULT. The WBDI driver sets this member to indicate the status result of the I/O operation.

The following list shows the possible biometric error values:

WINBIO_E_INVALID_UNIT

WINBIO_E_UNSUPPORTED_FACTOR

WINBIO_E_UNKNOWN_ID

WINBIO_E_CANCELED

WINBIO_E_NO_MATCH

WINBIO_I_MORE_DATA

WINBIO_E_CAPTURE_ABORTED

WINBIO_E_ENROLLMENT_IN_PROGRESS

WINBIO_E_BAD_CAPTURE

WINBIO_E_INVALID_DEVICE_STATE

WINBIO_E_DATA_COLLECTION_IN_PROGRESS

WINBIO_E_UNSUPPORTED_DATA_FORMAT

WINBIO_E_UNSUPPORTED_DATA_TYPE

WINBIO_E_DEVICE_BUSY

WINBIO_E_UNSUPPORTED_PURPOSE
