Remarks: The application should allocate response with malloc. The IoT Hub client SDK will free the data automatically.

Warning: The data in payload is not guaranteed to be a null-terminated string.

Returns: HTTP style return code to indicate success or failure of the method call.

◆ IOTHUB_CLIENT_DEVICE_TWIN_CALLBACK

typedef void(* IOTHUB_CLIENT_DEVICE_TWIN_CALLBACK) (DEVICE_TWIN_UPDATE_STATE update_state, const unsigned char *payLoad, size_t size, void *userContextCallback)

Signature of the callback that the application implements to process data received from an IoT Hub device or module twin.

Parameters

update_state	Whether application has received a full twin or just a patch update.
payLoad	Payload of twin received.

◆ IOTHUB_CLIENT_FILE_UPLOAD_CALLBACK

typedef void(* IOTHUB_CLIENT_FILE_UPLOAD_CALLBACK) (IOTHUB_CLIENT_FILE_UPLOAD_RESULT result, void *userContextCallback)

Deprecated callback mechanism for uploading data to a blob.

Deprecated:: This callback type is deprecated. Use the callback IOTHUB_CLIENT_FILE_UPLOAD_GET_DATA_CALLBACK_EX() instead.

◆ IOTHUB_CLIENT_FILE_UPLOAD_GET_DATA_CALLBACK

typedef void(* IOTHUB_CLIENT_FILE_UPLOAD_GET_DATA_CALLBACK) (IOTHUB_CLIENT_FILE_UPLOAD_RESULT result, unsigned char const **data, size_t *size, void *context)

Deprecated callback mechanism for uploading data to a blob.

Deprecated:: This callback type is deprecated. Use the callback IOTHUB_CLIENT_FILE_UPLOAD_GET_DATA_CALLBACK_EX() instead.

◆ IOTHUB_CLIENT_FILE_UPLOAD_GET_DATA_CALLBACK_EX

typedef IOTHUB_CLIENT_FILE_UPLOAD_GET_DATA_RESULT(* IOTHUB_CLIENT_FILE_UPLOAD_GET_DATA_CALLBACK_EX) (IOTHUB_CLIENT_FILE_UPLOAD_RESULT result, unsigned char const **data, size_t *size, void *context)

Signature of the callback that the application implements to process IoT Hub client SDK requesting additional chunks to upload to blob.

Parameters

result	The result of the upload of the previous block of data provided by the user.
data	Next block of data to be uploaded, to be provided by the user when this callback is invoked.
size	Size of the data parameter.
context	User context provided on the call to IoTHubClient_UploadMultipleBlocksToBlobAsync.

Returns: IOTHUB_CLIENT_FILE_UPLOAD_GET_DATA_RESULT indicating whether the application is returning data to be sent or not.

Remarks: If the user wants to abort the upload, the callback should return IOTHUB_CLIENT_FILE_UPLOAD_GET_DATA_ABORT It should return IOTHUB_CLIENT_FILE_UPLOAD_GET_DATA_OK otherwise. If a NULL is provided for parameter "data" and/or zero is provided for "size", the user indicates to the client that the complete file has been uploaded. In such case this callback will be invoked only once more to indicate the status of the final block upload. If result is not FILE_UPLOAD_OK, the upload is cancelled and this callback stops being invoked. When this callback is called for the last time, no data or size is expected, so data and size are NULL

◆ IOTHUB_CLIENT_LL_UPLOADTOBLOB_CONTEXT_HANDLE

typedef struct IOTHUB_CLIENT_LL_UPLOADTOBLOB_CONTEXT_STRUCT* IOTHUB_CLIENT_LL_UPLOADTOBLOB_CONTEXT_HANDLE

Remarks: struct IOTHUB_CLIENT_LL_UPLOADTOBLOB_CONTEXT_STRUCT contains information specifically related to an individual upload request currently active in Azure IoT Hub, mainly the correlation-id and Azure Blob SAS URI provided by the Azure IoT Hub when a new upload is started. The struct IOTHUB_CLIENT_LL_UPLOADTOBLOB_HANDLE_DATA on the other hand holds common information (independent from individual upload requests) that is used for upload-to-blob Rest API calls to Azure IoT Hub.

◆ IOTHUB_CLIENT_MESSAGE_CALLBACK_ASYNC

typedef IOTHUBMESSAGE_DISPOSITION_RESULT(* IOTHUB_CLIENT_MESSAGE_CALLBACK_ASYNC) (IOTHUB_MESSAGE_HANDLE message, void *userContextCallback)

Signature of the callback that the application implements to receive notifications of module initiated device method calls.

Parameters

result	Result of the operation
responseStatus	HTTP status code returned from the module or device. This is only valid if `result` is `IOTHUB_CLIENT_OK`.
responsePayload	HTTP response payload returned from the module or device. This is only valid if `result` is `IOTHUB_CLIENT_OK`.
responsePayloadSize	Number of bytes in `responsePayload`. This is only valid if `result` is `IOTHUB_CLIENT_OK`.
context	Context value passed is initial call to IoTHubModuleClient_ModuleMethodInvokeAsync() (e.g.).

Remarks: Module clients when hosted in IoT Edge may themselves invoke methods on either modules on the same IoT Edge device or on downstream devices using APIs such as IoTHubModuleClient_LL_DeviceMethodInvoke() or IoTHubModuleClient_LL_ModuleMethodInvoke(). These APIs operate asynchronously. When the invoked module or device returns (or times out), the IoT Hub SDK will invoke the application's IOTHUB_METHOD_INVOKE_CALLBACK() callback.

Warning: This API is only applicable to applications running inside a module container hosted by IoT Edge. Calling outside a IoT Edge hosted edge container will result in undefined results.

Enumeration Type Documentation

◆ IOTHUB_CLIENT_CONNECTION_STATUS

enum IOTHUB_CLIENT_CONNECTION_STATUS

Enumeration passed to the application callback indicating connection status changes to IoT Hub.

Remarks: IOTHUB_CLIENT_CONNECTION_AUTHENTICATED means the device or module client is ready to communicate with the Azure IoT Hub, being both connected and authenticated. IOTHUB_CLIENT_CONNECTION_UNAUTHENTICATED means the device or module client is not ready to communicate with the Azure IoT Hub. See the corresponding value of IOTHUB_CLIENT_CONNECTION_STATUS_REASON for more details.

◆ IOTHUB_CLIENT_CONNECTION_STATUS_REASON

enum IOTHUB_CLIENT_CONNECTION_STATUS_REASON

Enumeration passed to the application callback indicating reason that connection was unsuccessful.

Remarks: Each of the values of IOTHUB_CLIENT_CONNECTION_STATUS_REASON has a specific semantics depending on the transport protocol used. Here is a brief description of the reasons for each transport protocol: IOTHUB_CLIENT_CONNECTION_EXPIRED_SAS_TOKEN MQTT: The SAS token used in the current MQTT connection is expired and the client must reconnect with a new SAS token. AMQP: Not applicable. HTTP: Not applicable. IOTHUB_CLIENT_CONNECTION_DEVICE_DISABLED MQTT: An MQTT CONNECT to the Azure IoT Hub was rejected. AMQP: Not applicable. HTTP: Not applicable. IOTHUB_CLIENT_CONNECTION_BAD_CREDENTIAL MQTT: Not applicable. AMQP: A SAS-based authentication request failed. HTTP: Not applicable. IOTHUB_CLIENT_CONNECTION_RETRY_EXPIRED MQTT: The MQTT transport has made its maximum number of attempts to reconnect to the Azure IoT Hub and it will no longer try. AMQP: The AMQP transport has made its maximum number of attempts to reconnect to the Azure IoT Hub and it will no longer try. HTTP: Not applicable. IOTHUB_CLIENT_CONNECTION_NO_NETWORK MQTT: An MQTT CONNECT packet failed to be sent to the Azure IoT Hub for any reason. AMQP: A network connection issue was detected, which includes socket errors, failures on AMQP ATTACH to CBS link (for authentication). HTTP: Not applicable. IOTHUB_CLIENT_CONNECTION_COMMUNICATION_ERROR MQTT: A telemetry message timed out receiving a PUBACK from the Azure IoT Hub, there was an error sending a PUBACK or PUBREC to Azure IoT Hub, or an I/O error occurred when using WebSockets. AMQP: Authentication request timed out, received an unexpected link DETACH from Azure IoT Hub, or a link ATTACH timed out. HTTP: Not applicable. IOTHUB_CLIENT_CONNECTION_OK Applicable to all transport protocols. The Azure IoT C SDK client is connected and ready to communicate with the Azure IoT Hub. This reason is applicable only to IOTHUB_CLIENT_CONNECTION_AUTHENTICATED. IOTHUB_CLIENT_CONNECTION_NO_PING_RESPONSE MQTT: The MQTT transport timed out waiting for a ping response from the Azure IoT Hub. AMQP: Not applicable. HTTP: Not applicable. IOTHUB_CLIENT_CONNECTION_QUOTA_EXCEEDED MQTT: Not applicable. AMQP: The Azure IoT Hub rejected a telemetry message because the maximum daily quota of telemetry messages has been reached. HTTP: Not applicable.
