Beginning Linux Programming, 4th Edition

Building on the success of its previous editions, this must-have guide continues its popular tutorial approach and brings you a straightforward introduction to developing programs for Linux and other UNIX-style operating systems. The author duo of experienced Linux programmers covers a wide range of topics to help you learn more about what Linux has to offer so you can maximize your programming time and your use of the Linux system. You'll progress from the basics of compiling programs, linking to libraries, and dealing with terminal input and output to more advanced subjects such as writing applications for the GNOME and KDE environments, storing data using MySQL, and debugging. As each topic is covered, the authors introduce an appropriate programming theory and then illustrate it with practical examples, clear explanations, and a step-by-step approach with the intent that you will learn by doing. You'll quickly evolve from being a Linux beginner to confidently creating custom applications in Linux. What you will learn from this book • How to use the standard Linux C libraries and other facilities • Ways to make the most of the standard Linux development tools • Tips on basic system calls, file I/O, interprocess communication, and shell programming • How to build graphical user interfaces using the GTK+ or Qt toolkits • Using sockets to support TCP/IP networking to different machines • How to write programs that will work on different distributions of Linux Who this book is for This book is for programmers and developers who want to increase their skill level using Linux. Experience in C and/or C+ + programming is helpful.

Process Structure Starting New Processes Signals Summary Chapter 12: POSIX Threads What Is a Thread? Advantages and Drawbacks of Threads A First Threads Program Simultaneous Execution Synchronization Thread Attributes Canceling a Thread Threads in Abundance Summary Chapter 13: Inter-Process Communication: Pipes What Is a Pipe? Process Pipes Sending Output to popen The Pipe Call Parent and Child Processes Named Pipes: FIFOs The CD Database Application Summary Chapter 14: Semaphores, Shared Memory, and Message Queues Semaphores Shared Memory Message Queues The CD Database Application IPC Status Commands Summary Chapter 15: Sockets What Is a Socket? Socket Connections Network Information Multiple Clients Datagrams Summary Chapter 16: Programming GNOME Using GTK+ Introducing X Introducing GTK+ Events, Signals, and Callbacks Packing Box Widgets GTK+ Widgets GNOME Widgets GNOME Menus Dialogs CD Database Application Summary Chapter 17: Programming KDE Using Qt Introducing KDE and Qt Installing Qt Signals and Slots Qt Widgets Dialogs Menus and Toolbars with KDE CD Database Application Using KDE/Qt Summary Chapter 18: Standards for Linux The C Programming Language Interfaces and the Linux Standards Base The Filesystem Hierarchy Standard Further Reading about Standards Summary Index Beginning Linux Programming, Fourth Edition continues its unique approach to teaching UNIX programming in a simple and structured way on the Linux platform. Through the use of detailed and realistic examples, students learn by doing, and are able to move from being a Linux beginner to creating custom applications in Linux. The book introduces fundamental concepts beginning with the basics of writing Unix programs in C, and including material on basic system calls, file I/O, interprocess communication (for getting programs to work together), and shell programming. Parallel to this, the book introduces the toolkits and libraries for working with user interfaces, from simpler terminal mode applications to X and GTK+ for graphical user interfaces. Advanced topics are covered in detail such as processes, pipes, semaphores, socket programming, using MySQL, writing applications for the GNOME or the KDE desktop, writing device drivers, POSIX Threads, and kernel programming for the latest Linux Kernel.Source: Publisher
