Download e-book for iPad: The Linux Programming Interface: A Linux and UNIX System by Michael Kerrisk

The Linux Programming Interface is the definitive advisor to the Linux and UNIX programming interface—the interface hired by way of approximately each program that runs on a Linux or UNIX system.

In this authoritative paintings, Linux programming specialist Michael Kerrisk offers specified descriptions of the procedure calls and library services that you simply want which will grasp the craft of approach programming, and accompanies his factors with transparent, entire instance programs.

You'll locate descriptions of over 500 procedure calls and library services, and greater than two hundred instance courses, 88 tables, and one hundred fifteen diagrams. You'll find out how to:
• learn and write documents successfully
• Use indications, clocks, and timers
• Create methods and execute courses
• Write safe courses
• Write multithreaded courses utilizing POSIX threads
• construct and use shared libraries
• practice interprocess conversation utilizing pipes, message queues, shared reminiscence, and semaphores
• Write community functions with the sockets API

While The Linux Programming Interface covers a wealth of Linux-specific good points, together with epoll, inotify, and the /proc dossier process, its emphasis on UNIX criteria (POSIX. 1-2001/SUSv3 and POSIX. 1-2008/SUSv4) makes it both priceless to programmers engaged on different UNIX platforms.

The Linux Programming Interface is the main complete single-volume paintings at the Linux and UNIX programming interface, and a ebook that's destined to turn into a brand new classic.

Praise for The Linux Programming Interface

"If I needed to decide on a unmarried ebook to sit down subsequent to my computer whilst writing software program for Linux, this might be it. " —Martin Landers, software program Engineer, Google

"This booklet, with its precise descriptions and examples, comprises every little thing you want to comprehend the main points and nuances of the low-level programming APIs in Linux . . . it doesn't matter what the extent of reader, there'll be anything to be learnt from this booklet. " —Mel Gorman, writer of figuring out the Linux digital reminiscence Manager

"Michael Kerrisk has not just written a superb e-book approximately Linux programming and the way it pertains to numerous criteria, yet has additionally taken care that insects he spotted bought fastened and the guy pages have been (greatly) greater. In all 3 ways, he has made Linux programming more straightforward. The in-depth remedy of issues within the Linux Programming Interface . . . makes it a must have reference for either new and skilled Linux programmers. " —Andreas Jaeger, software supervisor, openSUSE, Novell

"Michael's inexhaustible decision to get his details correct, and to precise it truly and concisely, has led to a powerful reference resource for programmers. whereas this paintings is focused at Linux programmers, will probably be of worth to any programmer operating within the UNIX/POSIX environment. " —David Butenhof, writer of Programming with POSIX Threads and Contributor to the POSIX and UNIX Standards

". . . a really thorough—yet effortless to read—explanation of UNIX procedure and community programming, with an emphasis on Linux structures. It's definitely a booklet I'd suggest to anyone eager to get into UNIX programming (in normal) or to skilled UNIX programmers desirous to recognize 'what's new' within the well known GNU/Linux approach. " —Fernando Gont, community safeguard Researcher, IETF player, and RFC Author

". . . encyclopedic within the breadth and intensity of its insurance, and textbook-like in its wealth of labored examples and routines. every one subject is obviously and comprehensively coated, from conception to hands-on operating code. pros, scholars, educators, this can be the Linux/UNIX reference that you've got been awaiting. " —Anthony Robins, affiliate Professor of desktop technology, The college of Otago

"I've been very inspired by means of the precision, the standard and the extent of element Michael Kerrisk installed his e-book. he's an outstanding specialist of Linux procedure calls and we could us proportion his wisdom and realizing of the Linux APIs. " —Christophe Blaess, writer of Programmation systeme en C sous Linux

". . . an important source for the intense or specialist Linux and UNIX structures programmer. Michael Kerrisk covers using the entire key APIs throughout either the Linux and UNIX procedure interfaces with transparent descriptions and instructional examples and stresses the significance and advantages of following criteria resembling the one UNIX Specification and POSIX 1003. 1. " —Andrew Josey, Director, criteria, The Open workforce, and Chair of the POSIX 1003. 1 operating Group

"What can be larger than an encyclopedic connection with the Linux method, from the perspective of the procedure programmer, written by way of none except the maintainer of the fellow pages himself? The Linux Programming Interface is entire and special. I firmly anticipate it to turn into an fundamental addition to my programming bookshelf. " —Bill Gallmeister, writer of POSIX. four Programmer's advisor: Programming for the genuine World

". . . the main whole and up to date ebook approximately Linux and UNIX process programming. If you're new to Linux procedure programming, if you're a UNIX veteran inquisitive about portability whereas drawn to studying the Linux means, or if you're easily trying to find a good reference in regards to the Linux programming interface, then Michael Kerrisk's e-book is well the spouse you will have in your bookshelf. " —Loic Domaigne, leader software program Architect (Embedded), Corpuls. com

Get Learning the Korn Shell PDF

This Nutshell guide® is an intensive advent to the Korn shell, either as a consumer interface and as a programming language. The Korn shell, just like the C and Bourne shells, is a application that translates UNIX instructions. It has many positive factors that are not present in different shells, together with command historical past (the skill to bear in mind and edit earlier commands).

Example text

Fixed priority threads will be placed on the global run queue if you run schedtune -F1. 6 Time slices The CPUs on the system are shared amongst all the threads by giving each thread a certain slice of time to run. The default time slice of one clock tick (10 ms) can be changed using schedtune -t. Sometimes increasing the time slice improves system throughput due to reduced context switching. The vmstat and sar commands show the amount of context switching. If you see a high value of context switches, then increasing the time slice can improve performance.

A process can either ignore the signal or it can release memory pages using the disclaim() subroutine. npskill The operating system will begin killing processes when the amount of paging space left on the system goes below this threshold. When the npskill threshold is reached, the operating system sends a SIGKILL signal to the youngest process. Processes that are handling a SIGDANGER signal and processes that are using the EPSA policy are exempt from being killed. nokilluid By setting the value of the nokilluid value to 1 (one), the root processes will be exempt from being killed when the npskill threshold is reached.

1, “TCP/IP protocols” on page 31. 2, “Network tunables” on page 32. Chapter 1. Introduction to AIX performance monitoring and tuning 29 The knowledge of the network topology used is necessary to understand and detect possible performance bottlenecks on the network. This includes information about the routers and gateways used, the Maximum Transfer Unit (MTU) used on the network path between the systems, and the current load on the networks used. This information should be well documented, and access to these documents needs to be guaranteed at any time.
