For greater than 20 years, critical C programmers have depended on one publication for sensible, in-depth wisdom of the programming interfaces that force the UNIX and Linux kernels: W. Richard Stevens’ Advanced Programming within the UNIX® Environment . Now, once more, Rich’s colleague Steve Rago has completely up-to-date this vintage paintings. the hot 3rd version helps today’s prime systems, displays new technical advances and most sensible practices, and aligns with model four of the one UNIX Specification.

Steve conscientiously keeps the spirit and process that experience made this publication so beneficial. development on Rich’s pioneering paintings, he starts with documents, directories, and methods, rigorously laying the basis for extra complicated concepts, akin to sign dealing with and terminal I/O. He additionally completely covers threads and multithreaded programming, and socket-based IPC.

This variation covers greater than seventy new interfaces, together with POSIX asynchronous I/O, spin locks, obstacles, and POSIX semaphores. such a lot out of date interfaces were got rid of, with the exception of a couple of which are ubiquitous. approximately all examples were validated on 4 sleek systems: Solaris 10, Mac OS X model 10.6.8 (Darwin 10.8.0), FreeBSD 8.0, and Ubuntu model 12.04 (based on Linux 3.2).

As in earlier variations, you’ll research via examples, together with greater than 10000 traces of downloadable, ISO C resource code. greater than 400 process calls and features are confirmed with concise, entire courses that sincerely illustrate their utilization, arguments, and go back values. To tie jointly what you’ve realized, the e-book offers a number of chapter-length case reports, each one reflecting modern environments.

Advanced Programming within the UNIX® surroundings has helped generations of programmers write code with unparalleled strength, functionality, and reliability. Now up to date for today’s structures, this 3rd version might be much more worthy.

Example text

I welcome electronic mail from any readers with comments, suggestions, or bug fixes. Tucson, Arizona April 1992 W. 1 Introduction All operating systems provide services for programs they run. Typical services include executing a new program, opening a file, reading a file, allocating a region of memory, getting the current time of day, and so on. The focus of this text is to describe the services provided by various versions of the UNIX operating system. Describing the UNIX System in a strictly linear fashion, without any forward references to terms that haven’t been described yet, is nearly impossible (and would probably be boring).

How can we extend the overflow point? Are these strategies compatible with existing applications? 5 If the process time is stored as a signed 32-bit integer, and if the system counts 100 ticks per second, after how many days will the value overflow? 1 Introduction Much work has gone into standardizing the UNIX programming environment and the C programming language. S. government, to call for standardization. In this chapter we first look at the various standardization efforts that have been under way over the past two and a half decades.

The process hasn’t told the kernel to do anything other than the default with this signal, so the process terminates. To catch this signal, the program needs to call the signal function, specifying the name of the function to call when the SIGINT signal is generated. The function is named sig_int; when it’s called, it just prints a message and a new prompt. 10. 10 Read commands from standard input and execute them In Chapter 10, we’ll take a long look at signals, as most nontrivial applications deal with them.
