Release NotesThis 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. Written primarily for engineers looking to
program (better) at the low level, this book can give any programmer an
understanding of core internals that makes for better code, no matter where it
appears in the stack.
Full Description
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.
