//          Handle to the Bluetooth device from which to obtain the list of primary services.
//
//      ServicesBufferCount [in]
//          The number of elements allocated for the ServicesBuffer parameter.

//
//  Description:
//      Registers for a characteristic value change event on the given characteristic
//      identified by its characteristic handle.
//
//  Parameters:
//      hDevice [in]
//          Handle to the Bluetooth device or a service in the Bluetooth device.
//          For CharacteristicValueChangedEvent, this must be a service handle.
//
//      EventType [in]
//          CharacteristicValueChangedEvent: event callback to receive Handle Value Notifications or Handle Value Indications.
//
//      EventParameters [in]
//          CharacteristicValueChangedEvent: A pointer to BLUETOOTH_GATT_NOTIFICATION_REGISTRATION
//                                           that specifies the characteristics to be registered for the changed event notifications.
//
//      Callback [in]
//          The callback method to call when the Characteristic value changes.
//
//      CallbackContext [in]
//          A client context provided in the client provided callback function.
//
//      EventHandle [out]
//          Upon successful registration, this parameter receives a handle to this registration.
//          The client shall use this handle when calling BluetoothGATTUnregisterEvent.
