WINBIO_SET_INDICATOR structure (winbio_ioctl.h)
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. |
