Syntax

EVT_SENSOR_DRIVER_GET_SUPPORTED_DATA_FIELDS EvtSensorDriverGetSupportedDataFields;

NTSTATUS EvtSensorDriverGetSupportedDataFields(
  [in]                SENSOROBJECT Sensor,
  [in, out, optional] PSENSOR_PROPERTY_LIST pDataFields,
  [out]               PULONG pSize
)
{...}

Parameters

[in] Sensor

A reference to a sensor object.

[in, out, optional] pDataFields

A list of data fields that are supported by the given Sensor. For more information see SENSOR_PROPERTY_LIST.

[out] pSize

The size of pDataFields.

Return value

This function returns STATUS_SUCCESS when completed successfully.

Note

The class extension (CX) only uses the NT_SUCCESS macro to determine if the call to the driver’s Evt function was successful, but does not take any action if the function failed or does not return STATUS_SUCCESS.

Remarks

This function must be implemented by the driver and is called by the class extension.
