The WINBIO_SET_INDICATOR structure is the IN payload for IOCTL_BIOMETRIC_SET_INDICATOR.

Syntax

typedef struct _WINBIO_SET_INDICATOR {
  DWORD                   PayloadSize;
  WINBIO_INDICATOR_STATUS IndicatorStatus;
} WINBIO_SET_INDICATOR, *PWINBIO_SET_INDICATOR;

Members

PayloadSize

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

IndicatorStatus

Specifies a WINBIO_INDICATOR_STATUS that indicates whether the indicator light should be set on or off.

Possible values are shown in the following table.

Indicator status code Description
WINBIO_INDICATOR_ON The indicator light is on, and changes according to the sensor status. To be able to set WINBIO_INDICATOR_ON, you must set WINBIO_CAPABILITY_INDICATOR in the Capabilities member of the WINBIO_SENSOR_ATTRIBUTES structure.
WINBIO_INDICATOR_OFF The sensor indicator light is off. Sensors that do not have an indicator light will always return this value in IOCTL_GET_SENSOR_STATUS.
