/*
* This is an example of using a named-pipe for uni-directional communication.
* Client (./client) sends strings to the server (./server). You can run the two programs in separate terminals and observe the behavior.
* For bi-directional communication, two uni-directional pipes should be used.
* To compile: 
*
* g++ named-pipe-client.cpp -o client
* g++ named-pipe-server.cpp -o server
