Syntax

EVT_SENSOR_DRIVER_GET_SUPPORTED_DATA_FIELDS EvtSensorDriverGetSupportedDataFields;

  PULONG pSize
)
{...}

Parameters

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.
