Using UNIX Domain Stream Sockets
Example Using UNIX Domain Stream Sockets
* PITCH - SEND DATA TO THE CATCHER
*
* Pitch and catch set up a simple unix domain stream socket
* client-server connection. The client (pitch) then sends
* data to the server (catch), throughput is calculated, and
* the result is printed to the client's stdout.
