Dieses Buch beschreibt die Systemprogrammierung unter Linux/Unix. Unix bietet wie
jedes Betriebssystem sogenannte Systemaufrufe an, die von den Benutzerprogrammen
aus aufgerufen werden können, wenn diese bestimmte Dienste vom process benötigen.
Typische von einem Betriebssystem angebotene Dienste sind z.B. Öffnen einer Datei,
Schreiben auf eine Datei, Bereitstellen von freiem Speicherplatz oder Kommunizieren mit
Diese Systemaufrufe werden ebenso wie andere wichtige Funktionen aus der C-Stan-
dardbibliothek in diesem Buch anhand von zahlreichen anschaulichen Beispielen aus-
führlich beschrieben. Praxisnahe Übungen am Ende jedes Kapitels ermöglichen dem
Leser das Anwenden und Vertiefen der jeweils erworbenen Kenntnisse.
An entsprechenden Stellen wird in diesem Buch die Umsetzung von wichtigen Betriebs-
systemkonzepten und -algorithmen am method Linux gezeigt. Dieses procedure wurde nicht
nur aufgrund seiner großen Beliebtheit ausgewählt, sondern auch, weil Linux alle seine
Quellprogramme der Öffentlichkeit zur Verfügung stellt.
There are plenty of introductory C books, yet this can be the 1st person who has the no-nonsense, useful method that has made Nutshell Handbooks® famous.C programming is greater than simply getting the syntax correct. sort and debugging additionally play an incredible half in developing courses that run good and are effortless to keep up. This publication teaches you not just the mechanics of programming, but additionally describes the right way to create courses which are effortless to learn, debug, and update.Practical ideas are under pressure. for instance, there are fifteen priority principles in C (&& comes sooner than || comes earlier than ?:). the sensible programmer reduces those to two:
- Multiplication and department come ahead of addition and subtraction.
Contrary to renowned trust, such a lot programmers don't spend such a lot in their time growing code. such a lot in their time is spent editing a person else's code. This books exhibits you the way to prevent the all-too-common obfuscated makes use of of C (and additionally to acknowledge those makes use of in case you come across them in present courses) and thereby to depart code that the programmer chargeable for upkeep doesn't need to fight with. digital Archaeology, the artwork of facing a person else's code, is described.This 3rd version introduces well known built-in improvement Environments on home windows structures, in addition to UNIX programming utilities, and contours a wide statistics-generating application to tug jointly the suggestions and good points within the language.
