/** @file iothub_client_ll.h
*    @brief     APIs that allow a user (usually a device) to communicate
*             with an Azure IoTHub.
*
*    @details IoTHubClient_LL allows a user (usually a
*             device) to communicate with an Azure IoTHub. It can send events
*             and receive messages. At any given moment in time there can only
*             be at most 1 message callback function.
*
*             This API surface contains a set of APIs that allows the user to
*             interact with the lower layer portion of the IoTHubClient. These APIs
*             contain @c _LL_ in their name, but retain the same functionality like the
*             @c IoTHubClient_... APIs, with one difference. If the @c _LL_ APIs are
*             used then the user is responsible for scheduling when the actual work done
*             by the IoTHubClient happens (when the data is sent/received on/from the wire).
*             This is useful for constrained devices where spinning a separate thread is
*             often not desired.
