Structs
AAdditionalInfoEvent
ACameraCaptureFailure	Struct to describe a capture failure.
ACameraCaptureSession_captureCallbacks	ACaptureCaptureSession_captureCallbacks structure used in ACameraCaptureSession_capture and ACameraCaptureSession_setRepeatingRequest.
ACameraCaptureSession_captureCallbacksV2	This has the same functionality as ACameraCaptureSession_captureCallbacks, with the exception that captureCallback_startV2 callback is used, instead of captureCallback_start, to support retrieving the frame number.
ACameraCaptureSession_logicalCamera_captureCallbacks	This has the same functionality as ACameraCaptureSession_captureCallbacks, with the exception that an onLogicalCameraCaptureCompleted callback is used, instead of onCaptureCompleted, to support logical multi-camera.
ACameraCaptureSession_logicalCamera_captureCallbacksV2	This has the same functionality as ACameraCaptureSession_logicalCamera_captureCallbacks, with the exception that an captureCallback_startV2 callback is used, instead of captureCallback_start, to support retrieving frame number.
ACameraCaptureSession_stateCallbacks	Capture session state callbacks used in ACameraDevice_createCaptureSession and ACameraDevice_createCaptureSessionWithSessionParameters.
ACameraDevice_StateCallbacks	Applications' callbacks for camera device state changes, register with ACameraManager_openCamera.
