Who should attend: Programmers and system administrators who want to learn more about the essentials of UNIX programming and recent changes. Some programming experience in C is assumed.

In this tutorial, you will learn about current UNIX programming concepts required for systems programming, with a focus on the poorly documented features that tend to be the least understood. It does not cover the basic functions that most programmers are familiar with (open, lseek, STDIO).

You will also hear about the recent additions to the UNIX programming toolbag, specifically the 1996 POSIX.1 standard which includes the realtime and threads extensions and the UNIX 98 system which includes the Large File Summit and N-bit cleanup (64-bit and beyond).

Topics will include:

	Current UNIX standards
	File and directory I/O: I/O sharing, POSIX.1 changes, Large File Summit changes
	Process control: Startup & termination, race conditions, interpreter files
	Process relationships: Sessions, job control, daemons, error logging
	Signals, including POSIX.1 realtime signals    Record locking    I/O multiplexing    Memory mapped I/O    Interprocess communication: Coprocesses and new POSIX.1 IPC: messages, semaphores, and shared memory    POSIX.1 threads.
