can anybody give the example of interprocess communication?

Answer 1

Sure, if all you're looking for is a simple example, use unix command shell pipelines, which you pipe the output of one command into another, like "cat /etc/hosts | grep mailhost" this creates IPC between the cat and grep processes.

If you are looking for the classic examples of IPC and the issues surrounding it, Google for the "dining philosophers" problem or the "sleeping barber" problem.

In the context of networking, IPC is commonly accomplished using the socket interface, where pairs of sockets running in different processes exchange data, even on the same machine.

Answer 2

search google for IPC for theory on it... Inter Process communication can happen within machine boundaries or across machine boundaries . When it happens across machines you use what is called a remote procedure call.. (RPC)
