Detailed Description

Definition of az_result and helper functions.

Note
You MUST NOT use any symbols (macros, functions, structures, enums, etc.) prefixed with an underscore ('_') directly in your application code. These symbols are part of Azure SDK's internal implementation; we do not document these symbols and they are subject to change in future versions of the SDK which would break your code.

Enumeration Type Documentation

◆ anonymous enum

anonymous enum
Enumerator
AZ_HTTP_REQUEST_URL_BUFFER_SIZE 

The maximum buffer size for a URL.

AZ_HTTP_REQUEST_BODY_BUFFER_SIZE 

The maximum buffer size for an HTTP request body.

AZ_LOG_MESSAGE_BUFFER_SIZE 

The maximum buffer size for a log message.

◆ az_result

enum az_result

The type represents the various success and error conditions.

Enumerator
AZ_OK 

Success.

AZ_ERROR_CANCELED 

A context was canceled, and a function had to return before result was ready.

AZ_ERROR_ARG 

Input argument does not comply with the expected range of values.

AZ_ERROR_NOT_ENOUGH_SPACE 

The destination size is too small for the operation.

AZ_ERROR_NOT_IMPLEMENTED 

Requested functionality is not implemented.

AZ_ERROR_ITEM_NOT_FOUND

AZ_ERROR_HTTP_CORRUPT_RESPONSE_HEADER 

Error while parsing HTTP response header.

AZ_ERROR_HTTP_END_OF_HEADERS 

There are no more headers within the HTTP response payload.

AZ_ERROR_HTTP_ADAPTER 

Generic error in the HTTP transport adapter implementation.

AZ_ERROR_IOT_TOPIC_NO_MATCH
