| Inter-Process Communication (IPC) for client-server applications can be |
| accomplished using |
| [UNIX sockets](http://en.wikipedia.org/wiki/Unix_domain_socket). |
| |
| Both client and server need to use the same path for the socket. |
| |
| {common.rs} |
| |
| The client program: |
| |
| {client.rs} |
| |
| The server program: |
| |
| {server.rs} |
| |
| Let's test the programs |
| |
| ``` |
| $ rustc client.rs; rustc server.rs |
| |
| # Terminal 1 |
| $ ./server |
| Server started, waiting for clients |
| |
| # Terminal 2 |
| $ ./client hello |
| |
| # Terminal 1 |
| Server started, waiting for clients |
| Client said: hello |
| ``` |
