COURSE OBJECTIVES
Linux Programming and Introduction to X is designed to quickly bring experienced programmers up to speed in a Linux environment. Upon completion of the course, students will be comfortable on a Linux system and will understand the fundamentals of the X Window System.
Students will learn:
- Programming in C in a Linux environment.
- Shell programming.
- Linux Concepts/Techniques including standards and compliance, working with files, processes and signals, inter-process communication, semaphores, messages, shared memory and sockets.
- Linux Programming in C including makefiles, version control, compiling, linking and debugging.
- GUI Development using the X Window System including X concepts, basic X programming in C, window attributes, the graphics context, drawing graphics and text, color, events, keyboard and mouse.
TEXTS
- Beginning Linux Programming by Neil Matthew & Richard Stones
- Xlib Programming Manual by Adrian Nye
- Linux/etc by Terry Griffin; articles reprinted from Computer Bits magazine, Nov. 1996 - Jan. 1999
INSTRUCTIONAL APPROACH
This course will be taught in a classroom with one computer per student. The emphasis will be on hands-on programming, with roughly one half of the total time being spent on labs and exercises. The Red Hat 5.2 Linux distribution will be used with the KDE desktop environment.
The class is divided into 23 sessions, each consisting of both lecture and lab. The lectures are intended to be interactive and will include review of the lab assignments. The sessions range from 0.5 hours to 5 hours, and are presented over a period of 5 days.
PREREQUISITES
- Students should be proficient in the C programming language.
- Successful completion of Axian's Linux Use and Administration course, or equivalent.
