| XinZhangMS | 0:f7f1f0d76dd6 | 5 | * @brief APIs that allow a user (usually a module) to communicate |
| XinZhangMS | 0:f7f1f0d76dd6 | 6 | * with an Azure IoTHub. |
| XinZhangMS | 0:f7f1f0d76dd6 | 7 | * |
| XinZhangMS | 0:f7f1f0d76dd6 | 8 | * @details IoTHubModuleClient_LL is a module that allows a user (usually a |
| XinZhangMS | 0:f7f1f0d76dd6 | 9 | * module) to communicate with an Azure IoTHub. It can send events |
| XinZhangMS | 0:f7f1f0d76dd6 | 10 | * and receive messages. At any given moment in time there can only |
| XinZhangMS | 0:f7f1f0d76dd6 | 11 | * be at most 1 message callback function. |
| XinZhangMS | 0:f7f1f0d76dd6 | 12 | * |
| XinZhangMS | 0:f7f1f0d76dd6 | 13 | * This API surface contains a set of APIs that allows the user to |
| XinZhangMS | 0:f7f1f0d76dd6 | 14 | * interact with the lower layer portion of the IoTHubClient. These APIs |
| XinZhangMS | 0:f7f1f0d76dd6 | 15 | * contain @c _LL_ in their name, but retain the same functionality like the |
| XinZhangMS | 0:f7f1f0d76dd6 | 16 | * @c IoTHubModuleClient_... APIs, with one difference. If the @c _LL_ APIs are |
| XinZhangMS | 0:f7f1f0d76dd6 | 17 | * used then the user is responsible for scheduling when the actual work done |
| XinZhangMS | 0:f7f1f0d76dd6 | 18 | * by the IoTHubClient happens (when the data is sent/received on/from the wire). |
| XinZhangMS | 0:f7f1f0d76dd6 | 19 | * This is useful for constrained devices where spinning a separate thread is |
| XinZhangMS | 0:f7f1f0d76dd6 | 20 | * often not desired. |
