GCC extensions to the C language Write software that draws directly on services offered by the Linux kernel and core system libraries. With this comprehensive book, Linux kernel contributor Robert Love provides you with a tutorial on Linux system programming, a reference manual on Linux system calls, and an insider’s guide to writing smarter, faster code.Love clearly distinguishes between POSIX standard functions and special services offered only by Linux. With a new chapter on multithreading, this updated and expanded edition provides an in-depth look at Linux from both a theoretical and applied perspective over a wide range of programming topics, including:A Linux kernel, C library, and C compiler overviewBasic I/O operations, such as reading from and writing to filesAdvanced I/O interfaces, memory mappings, and optimization techniquesThe family of system calls for basic process managementAdvanced process management, including real-time processesThread concepts, multithreaded programming, and PthreadsFile and directory managementInterfaces for allocating memory and optimizing memory accessBasic and advanced signal interfaces, and their role on the systemClock management, including POSIX clocks and high-resolution timers Write software that draws directly on services offered by the Linux kernel and core system libraries.

Write software that makes the most effective use of the Linux system, including the kernel and core system libraries. The majority of both Unix and Linux code is still written at the system level, and this book helps you focus 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 at the low level, this updated edition of Linux System Programming gives you an understanding of core internals that makes for better code, no matter where it appears in the stack. -- Provided by publisher 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.
