This book is about writing software that makes the most effective use of the
system you're running on -- code that interfaces directly with the kernel and
core system libraries, including the shell, text editor, compiler, debugger,
core utilities, and system daemons. The majority of both Unix and Linux code
is still written at the system level, and Linux System Programming focuses on
everything above the kernel, where applications such as Apache, bash, cp, vim,
Emacs, gcc, gdb, glibc, ls, mv, and X exist.
Written primarily for engineers looking to program (better) at the low level,
this book is an ideal teaching tool for any programmer. Even with the trend
toward high-level development, either through web software (such as PHP) or
managed code (C#), someone still has to write the PHP interpreter and the C#
virtual machine. Linux System Programming gives you an understanding of core
internals that makes for better code, no matter where it appears in the stack.
Debugging high-level code often requires you to understand the system calls
and kernel behavior of your operating system, too.
Key topics include:
* An overview of Linux, the kernel, the C library, and the C compiler
* Reading from and writing to files, along with other basic file I/O operations,
including how the Linux kernel implements and manages file I/O
* Buffer size management, including the Standard I/O library
* Advanced I/O interfaces, memory mappings, and optimization techniques
* The family of system calls for basic process management
* Advanced process management, including real-time processes
* File and directories-creating, moving, copying, deleting, and managing them
* Memory management -- interfaces for allocating memory, managing the memory
you have, and optimizing your memory access
* Signals and their role on a Unix system, plus basic and advanced signal interfaces
* Time, sleeping, and clock management, starting with the basics and continuing
through POSIX clocks and high resolution timers
With Linux System Programming, you will be able to take an in-depth look at
Linux from both a theoretical and an applied perspective as you cover a wide
range of programming topics.

About the Author
Robert Love has used Linux since the early days. He is involved in and passionate
about both the Linux kernel and GNOME communities. He has written and maintained
numerous projects, including the preemptive kernel, GNOME Volume Manager, and
inotify.
Robert is Chief Architect, Linux Desktop, at Novell.
He is the author of Linux Kernel Development (SAMS 2005) and the co-author
of Linux in a Nutshell (2006 O'Reilly). He is currently working on a new work
for O'Reilly that will be the greatest book ever written, give or take.
Robert is a Contributing Editor at Linux Journal.
He holds a B.A. in Mathematics and a B.S. in Computer Science from the University
of Florida. A proud Gator, Robert was born in South Florida but currently calls
home Cambridge, MA.
