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	Requested item was not found.
AZ_ERROR_UNEXPECTED_CHAR	Input can't be successfully parsed.
AZ_ERROR_UNEXPECTED_END	Unexpected end of the input data.
AZ_ERROR_NOT_SUPPORTED	Not supported.
AZ_ERROR_DEPENDENCY_NOT_PROVIDED	An external dependency required to perform the operation was not provided. The operation needs an implementation of the platform layer or an HTTP transport adapter.
AZ_ERROR_OUT_OF_MEMORY	Dynamic memory allocation request was not successful.
AZ_ERROR_JSON_INVALID_STATE	The kind of the token being read is not compatible with the expected type of the value.
AZ_ERROR_JSON_NESTING_OVERFLOW	The JSON depth is too large.
AZ_ERROR_JSON_READER_DONE	No more JSON text left to process.
AZ_ERROR_HTTP_INVALID_STATE	The az_http_response instance is in an invalid state.
AZ_ERROR_HTTP_PIPELINE_INVALID_POLICY	HTTP pipeline is malformed.
AZ_ERROR_HTTP_INVALID_METHOD_VERB	Unknown HTTP method verb.
AZ_ERROR_HTTP_AUTHENTICATION_FAILED	Authentication failed.
AZ_ERROR_HTTP_RESPONSE_OVERFLOW	HTTP response overflow.
AZ_ERROR_HTTP_RESPONSE_COULDNT_RESOLVE_HOST	Couldn't resolve host.
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	The IoT topic is not matching the expected format.
AZ_ERROR_IOT_END_OF_PROPERTIES	While iterating, there are no more properties to return.

Function Documentation
