Linux System Programming

Write software that makes the most effective use of the Linux system, including the kernel and core system libraries. Written primarily for engineers looking to program at the low level, Linux System Programming gives you an understanding of core internals that makes for better code, no matter where it appears in the stack.

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 overview
• Basic I/O operations, such as reading from and writing to files
• 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
• Thread concepts, multithreaded programming, and Pthreads
• File and directory management
• Interfaces for allocating memory and optimizing memory access
• Basic and advanced signal interfaces, and their role on the system
• Clock management, including POSIX clocks and high-resolution timers
