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.
