WBF IOCTL_BIOMETRIC_CAPTURE_DATA status code on failure RRS feed

  • Question

  • Hello,

    I don't know if it's the most relevant forum for this kind of question, but this is it:

    It's about development of WBDI (Windows Biometric Driver Interface) for WBF (Windows Biometric Framework) using UMDF v2 (User-Mode Driver Framework).
    I have a question on the implementation of IOCTL_BIOMETRIC_CAPTURE_DATA when there is a failure (like WINBIO_E_DATA_COLLECTION_IN_PROGRESS for example).

    Should we propagate this error code:

    • from WINBIO_CAPTURE_DATA.WinBioHresult field
    • or from the I/O Status Block of the IOCTL request like WdfRequestComplete(Request, NTSTATUS_FROM_WIN32(WINBIO_E_DATA_COLLECTION_IN_PROGRESS))?

    Thanks for your support,

    Regards,
    Nico
