Overview

Unix and Linux provide many powerful facilities such as multi-tasking and inter-process communication. A thorough understanding of these facilities enables programmers to write effective and robust applications.

The techniques covered in this course are applicable to most major Unix and Linux distributions.

Objectives

On successful completion of this course, participants will be able to write Unix and Linux applications that:

• Use the system facilities
• Perform I/O
• Utilise file and record locking
• Access devices directly
• Perform memory management tasks
• Create and control other processes
• Communicate with other processes

Audience

This course is for programmers and analysts who wish to write Unix or Linux applications in C.

Prerequisites

Participants must have a knowledge of C or C++ up to the level covered in the C Programming course, and a knowledge of Unix or Linux up to the level covered in the Unix and Linux Fundamentals course.
