Sockets
These programs are provided as examples only of UNIX Domain stream
NOTE
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.
