Overview

Legato's environment lets you create and run multiple applications in different ways:

OEM's can create Legato apps to run on their specific hardware.
3rd party software providers can create apps for different kinds of hardware.

To help support the different development needs, Legato has two levels of services:

Application Services

high-level APIs that can be used by several apps.
fully managed arbitration among apps lets you share the same resources.

Foundation Services

full-featured APIs to various foundational system and modem resources.
thread safe functions like get()can be called from any app.
command and response functions like startaction() or set()are thread safe; a single app can call them, or they can manage their own resource arbitration between selected apps.

Legato also provides a simple form of interface definition language (IDL) similar to C. It helps define APIs so they can be used in multiple, different programming languages. See Language-independent APIs.
