Advanced Linux System Programming

4 days
LX3 - Version:2
Description
The course introduces the participant to programming in the C programming language in a Linux environment. The course focuses on Linux system calls and library functions, how to use them, and their underlying mechanisms. The course deals with many facets of the Linux operating system, including: Linux kernel structure, I/O, Signals, Timers, Processes, Threads, IPC mechanisms: Pipes, Shared memory, Message Queues, Semaphores, and Sockets using TCP and UDP. The course includes many programming examples that can serve as a reference or basis for the participants' work in the future. Time is given to writing and testing several programs to help the participants comprehend the complexity of Linux system programming, along with the satisfaction of knowing how to do it well.
Intended audience
The course is for programmers, software designers, and project managers.
