Course Description:

'' this course discusses the use of system-level programming interfaces provided by unix and linux to develop applications.

the course is illustrated with practical examples in unix’s ‘native�c language which show how to write programs to exploit the features of unix and how to choose the correct api calls for the task. unix is an excellent environment for client/server programming. you will learn how toboth client and server applications using sockets and other inter-process communication methods, and how torobust multi-threaded applications using the standard pthreads library.

the course concentrates on a common approach to the different variants of unix, using the single unix specification (sus) and explores features available in to x/open system interface (xsi). this broad-ranging unix course is designed to provide delegates with the skills and knowledge which is applicable to all flavours of unix including linux, hp-ux, unixware, solaris, aix etc.

prerequisites
delegates must have a good working knowledge of the c programming language. this can be gained by attending our c programming course.
a familiarity with unix processes, system calls and general philosophy is assumed. this can be gained from attending qa-iq’s unix fundamentals course.
delegates will learn how to
write programs that can access and update information in files
use the concepts of the unix virtual memory system
handle signals in a safe and reliable way
program unix and internet sockets interfaces
build multi-process applications
understand passing information between co-operating processes using ipc
implement unix client/server applications
create multi-threaded programs and synchronise shared resources
