A pointer to the returned percentage value.

Use this function to get the available video light power level, as a percentage of the maximum. A non-zero level indicates that there is sufficient power available to turn on the video light (see camera_config_videolight()). You can listen for CAMERA_STATUS_VIDEOLIGHT_LEVEL_CHANGE status events to know when the video light power level has changed from its previous value.
