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
