Overview - Legato Docs

Legato's Services APIs are pre-built IPC interfaces designed to create and run multiple apps in different ways:

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

Many Services APIs provided are multi-app safe:

APIs can be used by several apps.
arbitration fully managed among apps so multiple apps can share the same resources.

Other Services provide full-featured interface access to 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 interface definition language (IDL) similar to C. It helps define APIs so they can be used in multiple, different programming languages. See API Files.

Warning: Some Services shouldn't be used together in the same app (e.g., if you use a muli-app safe service like Data Connection, you can't also use the Modem Data Control service).
