Ioto Agent Reference Guide

This guide describes the Ioto agent programming APIs.

Before reading the APIs, you may wish to review some architectural overviews that explain the programming paradigms used by Ioto.

Architectural Overviews

• Ioto Background
• Memory Allocation
• Fiber Coroutine Programming

Programming APIs

The Ioto agent native APIs consist of C language headers, function prototypes, structure definitions and defines. They are divided into one of these areas.

Area	Description
Ioto	Agent API
Web Server	Embedded Web Server
DB	Embedded Database
MQTT	MQTT protocol client
URL	Http Client
JSON	JSON parser and query engine
Crypt	Crypto APIs
R	Portable Runtime
OSDEP	O/S Portability Layer

Stability Classifications

In addition to supporting SemVer for Ioto version policy, we provide stability classifications.

APIs stability classifications document the likelihood of future change on a per-API basis. Rather than a general, meaningless backwards compatibility promise, these Stability Classifications assist developers to understand the future risk of change.
