AzureIoTClient 16:deba40344375 5 * @brief APIs that allow a user (usually a device) to communicate
AzureIoTClient 16:deba40344375 6 * with an Azure IoTHub.
AzureIoTClient 16:deba40344375 7 *
AzureIoTClient 16:deba40344375 8 * @details IoTHubClient_LL is a module that allows a user (usually a
AzureIoTClient 16:deba40344375 9 * device) to communicate with an Azure IoTHub. It can send events
AzureIoTClient 16:deba40344375 10 * and receive messages. At any given moment in time there can only
AzureIoTClient 16:deba40344375 11 * be at most 1 message callback function.
AzureIoTClient 40:1a94db9139ea 12 *
AzureIoTClient 16:deba40344375 13 * This API surface contains a set of APIs that allows the user to
AzureIoTClient 16:deba40344375 14 * interact with the lower layer portion of the IoTHubClient. These APIs
AzureIoTClient 16:deba40344375 15 * contain @c _LL_ in their name, but retain the same functionality like the
AzureIoTClient 16:deba40344375 16 * @c IoTHubClient_... APIs, with one difference. If the @c _LL_ APIs are
AzureIoTClient 16:deba40344375 17 * used then the user is responsible for scheduling when the actual work done
AzureIoTClient 16:deba40344375 18 * by the IoTHubClient happens (when the data is sent/received on/from the wire).
AzureIoTClient 16:deba40344375 19 * This is useful for constrained devices where spinning a separate thread is
AzureIoTClient 16:deba40344375 20 * often not desired.

AzureIoTClient 53:1e5a1ca1f274 456 * @p value is pointing to are specific for every option.
AzureIoTClient 53:1e5a1ca1f274 457 *
AzureIoTClient 53:1e5a1ca1f274 458 * @param iotHubClientHandle The handle created by a call to the create function.

AzureIoTClient 53:1e5a1ca1f274 461 *
AzureIoTClient 53:1e5a1ca1f274 462 * The options that can be set via this API are:
AzureIoTClient 53:1e5a1ca1f274 463 * - @b timeout - the maximum time in milliseconds a communication is
AzureIoTClient 53:1e5a1ca1f274 464 * allowed to use. @p value is a pointer to an @c unsigned @c int with
AzureIoTClient 53:1e5a1ca1f274 465 * the timeout value in milliseconds. This is only supported for the HTTP
AzureIoTClient 53:1e5a1ca1f274 466 * protocol as of now. When the HTTP protocol uses CURL, the meaning of
AzureIoTClient 53:1e5a1ca1f274 467 * the parameter is <em>total request time</em>. When the HTTP protocol uses
AzureIoTClient 53:1e5a1ca1f274 468 * winhttp, the meaning is the same as the @c dwSendTimeout and
