Interprocess communication Posix

Question

Hi all,

I am working on a debian system and have to communicate some processes so i am looking for some advise or documentation ...

As an imposed rule, i cannot use any library such as boost, so i am trying to choose between systemV IPC and POSIX ipc facilities , but i have not found any good document about the later. ¿Could you please help me?

Also i have been looking for a ipc best practices manual or something like that... Do you know anyone?

Thanks in advance (and forgive me for my English )

Answer 1

Here's a nice tutorial/guide

Answer 2

One best practice for IPC is the pipeline.

process | anotherProcess

Is a form of IPC. One process is a writer to a buffer, the other process is a reader from a buffer.

This is fast, trivial to implement, requires no specialized knowledge or libraries, is supported directly by the shell and the OS.

Few things are as simple as the pipeline.

Answer 3

The following are great books describing all you are asking about:

Unix Systems Programming, Robbins and Robbins.

Advanced Programming in the UNIX Environment, Stevens.

They both do a great job talking about SYSV and POSIX IPC approaches and are the staple in college curriculum for CS.

Answer 4

Chapter 5 (PDF) of Advanced Linux Programming is an excellent description of IPC methods in Linux. It covers sockets, pipes, and System V IPC, but not POSIX IPC.
