<P>Now that we've seen how to create servers, let's spend just a moment

making a client. Since this is so easy, I'm going to do all of it in this

one page.

X

<P>

Kirthika says, "Here's an one paragraph abstract for a one page client app:"
X
<UL>
X				The server is an Stream object of ACE_SOCK_Stream type. The
X				ACE_Sock_Connector does the job of actively making a connection with the
X				listening server. It does so using the server_host_address and port
X				number which are stored in the ACE_INET_Addr object.Once the
X				connection has been established, the client begins its interaction
X				with the server and bombards it with messages.
X				Note: send_n() call is used since this call sees to the issues of
X				network buffering and reliably gets the data across to the server.
X				Also, a timeout value is set to provide fault tolerance if the server
X				ever dies before the transaction is completed. The server calls a
X				close() method
X				once it reads in zero bytes during the Event_Handler::handle_input()
X				call. This
X				proves that the client has severed its connection. The server then
X				shuts down.

<P>Ok, so that was pretty easy. What would be even easier would be to wrap

all of the connection mess up in an object and overload a couple of basic

operators to make things less network-centric. Perhaps we'll see that in

another tutorial.
