EVT_SENSOR_DRIVER_START_SENSOR callback function (sensorscx.h)

This callback function starts the sensor based on the default properties specified by the driver, or properties set by the class extension.

Syntax

EVT_SENSOR_DRIVER_START_SENSOR EvtSensorDriverStartSensor;

NTSTATUS EvtSensorDriverStartSensor(
  SENSOROBJECT Sensor
)
{...}

Parameters

Sensor

A reference to a sensor object.

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 only once by the class extension.
