I was reading about pipes today, it seems an interesting for me to use it or to start about it. but it's written there that the processes should be like a parent and child or client server and the communication will be between them.
there are some things I don't understand and before start I should be sure about them.
If I have a running process for example on my machine, and I want to send message to it, of course I can't control it, so how can I make it respond to my messages?? should I create the client and server and run them both?? Or the running process application can be a server for example and I can send some events to it??
if you can help me in this :)
