Introduction

This chapter discusses interprocess communication (IPC) in Linux. Interprocess communication is a way for multiple processes in Linux to communicate with each other. First, interprocess communication and the resources it uses are defined. The chapter then discusses how to use the ipcs command to learn about the IPC resources on the system. Next, the various parameters available for the different IPC resources are discussed. The chapter then tells how to modify IPC parameters both statically and dynamically. Finally, the role of pipes as IPC facilities in Linux is discussed.
