Advanced Red Hat Linux Systems Programming


				Course Description

	This course introduces the participants to system level programming in the C 
	language in a RHEL5 environment. The course focuses on RHEL5 system calls and 
	library functions, how to use them, and their underlying mechanisms. The course 
	deals with many facets of the RHEL5 operating system, including: introduction to 
	RHEL5 kernel structure, I/O, Signals, Signal handlers, Timers, Processes, Multi-Tasking, 
	Inter-Process Communication (IPC) Pipes, Shared memory, Message Queues, Semaphores, 
	Networking, Sockets, using TCP/IP and UDP/IP.Throughout the course the information 
	presented is related to the participant through:  the execution of common RHEL5 
	user/administrator commands, and writing, compiling, and executing example C language 
	programs which demonstrate the use of system routines and accessing system data structures 
	on a live RHEL5 system. 


				Course Objectives

	Upon completion of this course the participant will be able to:
	•	Explain the programmable mechanisms in a RHEL5 environment 
	•	Write applications using standard RHEL5 system calls and library functions

			Course Duration

	This course normally requires five (5) days, 60% lecture, 40% hands 
	on lab exercises.


			Course Prerequisites

	It is assumed that the participant has a solid background in basic RHEL5
	utilities and editors (such as vi), and a working knowledge of the C (or C++) 
	programming language(s).
