+ * @brief   Gets an attribute to control the behavior of a sensor listener.
+ * @details Applications can change the behavior of a sensor listener, for example,
+ *          what is the reference coordinate of the sensor values,
+ *          and when the system is allowed to turn off the sensor implicitly to reduce the power consumption.
+ *          See #sensor_attribute_e for more details about the available control parameters.
+ * @since_tizen 7.0
+ *
+ * @param[in]   listener     A listener handle
+ * @param[in]   attribute    An attribute to change.
+ *                           It should be in the range each sensor_attribute_e,
+ *                           or should be fixed enum value such as sensor_axis_e or sensor_pause_e.
+ * @param[out]  value        An attribute value
+ *
+ * @return  #SENSOR_ERROR_NONE on success, otherwise a negative error value
+ * @retval  #SENSOR_ERROR_NONE                 Successful
+ * @retval  #SENSOR_ERROR_INVALID_PARAMETER    Invalid parameter
+ * @retval  #SENSOR_ERROR_OPERATION_FAILED     Operation failed
