Linux Application Development (2nd Edition)

If you are already a proficient Unix programmer, this book will greatly facilitate your transition to Linux. You will also find helpful discussions of some tricky Unix topics, such as process and session groups, job control, and tty handling.If you are a C programmer, but know neither Unix nor Linux, reading this book in its entirety and working with its numerous examples will give you a solid introduction to Linux programming. "The first edition of this book has always been kept within arm's reach of my desk due to the wonderful explanations of all areas of the Linux userspace API. This second edition greatly overshadows the first one, and will replace it." --Greg Kroah-Hartman, Linux kernel programmer Develop Software that Leverages the Full Power of Today's Linux Linux Application Development, Second Edition, is the definitive reference for Linux programmers at all levels of experience, including C programmers moving from other operating systems. Building on their widely praised first edition, leading Linux programmers Michael Johnson and Erik Troan systematically present the key APIs and techniques you need to create robust, secure, efficient software or to port existing code to Linux. This book has been fully updated for the Linux 2.6 kernel, GNU C library version 2.3, the latest POSIX standards, and the Single Unix Specification, Issue 6. Its deep coverage of Linux-specific extensions and features helps you take advantage of the full power of contemporary Linux. Along the way, the authors share insights, tips, and tricks for developers working with any recent Linux distribution, and virtually any version of Unix. Topics include Developing in Linux: understanding the operating system, licensing, and documentation The development environment: compilers, linker and loader, and unique debugging tools System programming: process models, file handling, signal processing, directory operations, and job control Terminals, sockets, timers, virtual consoles, and the Linux console Development libraries: string matching, terminal handling, command-line parsing, authentication, and more Hundreds of downloadable code samples New to this edition The GNU C library (glibc), underlying standards, and test macros Writing secure Linux programs, system daemons, and utilities Significantly expanded coverage of memory debugging, including Valgrind and mpr Greatly improved coverage of regular expressions IPv6 networking coverage, including new system library interfaces for using IPv6 and IPv4 interchangeably Coverage of strace, ltrace, real-time signals, poll and epoll system calls, popt library improvements, Pluggable Authentication Modules (PAM), qdbm, and much more Improved index and glossary, plus line-numbered code examples. Linux Application Development, Second Edition, is the definitive reference for Linux programmers at all levels of experience, including C programmers moving from other operating systems. Building on their widely praised first edition, leading Linux programmers Michael Johnson and Erik Troan systematically present the key APIs and techniques you need to create robust, secure, efficient software or to port existing code to Linux. Linux Application Development is divided into four parts. Part 1 introduces you to Linux(the operating system, licenses, and documentation. Part 2 covers the most important aspects of the development environment(the compilers, linker, loader, and debugging tools. Part 3-the heart of the book-describes the interface to the kernel and to the core system libraries, including discussion of the process model, file handling, directory operations, signal processing (including the Linux signal API), job control, the POSIX(termios interface, sockets, and the Linux console. Part 4 describes important development libraries with interfaces more independent of the kernel. The source code from the book is freely available at http://www.awl.com/cseng/books/lad Michael K.
