The Current set of articles delve into system programming in Linux. The current set of articles deal with thread programming, pipes, user/kernel space interactions, system interaction etc. There are example code placed for most discussions. Most of the topics are discussed with an effort to get a reader comfortable with the concepts and to proceed further.

Kindly note – this section is still under construction. It will be updated soon.

Socket programming is discussed separately in the socket programming in Linux tab as a separate section.

Some good books and references for System programming in Linux are

• The linux Programming Interface – Michael Kerrisk
• Linux system Programming – Robert Love
