Overview

This course explores the system-level programming interfaces provided by Linux to develop applications and Embedded Linux Systems.

The course covers all the services provided by the C-Library to the application layer: accessing and handling files, creating processes and threads, IPC and many more

On Completion, Delegates will be able to

Understand the Linux programming model

Create and manage processes and threads

Using synchronization objects and IPC effectively

Debugging applications

Who Should Attend

The course is designed for developers who need to make their first steps in Linux development
