interprocess communication in C++

Hello!

What mechanisms are usually used for interprocess communication in C++? When
project consists of several processes located at different network nodes how
it is easier to program all the messaging between processes/classes.
Example: one class calls the function from another class that is located on
another computer.

Thank you for any keywords!

You have a couple of options to do that:

1. SUN-RPC - stone old, but still works. Not very nice to use from C++,
though.
2. XML-RPC - newer, free libraries are available, some have a C++ interface.
3. CORBA - not so new, but can be used very elegantly and clean if you
stick to the basics (read "Advanced CORBA Programming with C++" by Henning/
Vinoski to avoid troubles).

.... this list is not complete, feel free to fill it up.

I've personally used 2 & 3 and would not again use XML-RPC. SUN-RPC is almost
dead, so I would recommend CORBA. There are a lot of free ORBs around (TAO,
omniORB, etc.), you have a nice IDL, etc.

YMMV,
Uli

C++ has no native IPC mechanisms. However, you can use any of Linux' through
the standard Linux APIs: sockets, pipes, named pipes, semaphores, shared
memory, message queues, etc.

However, you seem to be asking not about interprocess communication, but
rather network communication. In that case there's the low-level network
APIs and for things like computing clusters there's stuff like MPI, PVM,
MOSIX, etc.
