Using UNIX Domain Stream Sockets

Example Using UNIX Domain Stream Sockets

Example Using UNIX Domain Stream

Sockets

NOTE

These programs are provided as examples only of UNIX Domain stream

socket usage and are not Hewlett-Packard supported products.

These programming examples demonstrate how to set up and use UNIX

Domain stream sockets. These sample programs can be found in the

/usr/lib/demos/networking/af_unix

directory. The client program

is intended to run in conjunction with the server program.

This example shows how to create UNIX Domain stream sockets and

how to set up address structures for the sockets. In this example the

client process sends 2000 bytes of data to the server (ﬁve times). The

server process can receive data from any other process and will echo the

data back to the sender.

Sample Program: AF_UNIX stream sockets, server process

CATCH - RECEIVE DATA FROM THE PITCHER

*

*

Pitch and catch set up a simple unix domain stream socket

*

client-server connection. The client (pitch) then sends

*

data to server (catch), throughput is calculated, and the

*

result is printed to the client's stdout.
