This section defines the IOCTLs that make up the Windows Biometric Driver Interface (WBDI). This is the IOCTL set called by the Sensor Adapter in the Windows Biometric Service (WBS). Each of the IOCTLs can be canceled by the caller. The caller can get control back by issuing asynchronous overlapped I/O. The caller uses CancelIo or CancelIoEx to cancel I/O requests.
For all IOCTLs in this section, the input/output buffers are contiguous data buffers.
Vendor-supplied WBDI drivers must support these IOCTLs:
Optional IOCTLs include:
