(This tutorial is actually where ACE_IOStream +was born.) +<P> +Kirthika says: +<UL> +The cool thing about this "cooler" client is how we use a C++ trick for +streaming incoming data by using the operator<<() metod. Also the +Connector portion is wrapped in the open() method which now takes in the +server hostname and port.

As you can see, it really isn't +so hard to create an object that makes sending data much more "natural" +than the typical send() or send_n() invocation. You can even build +up arbitrary objects & do some neat tricks with C++ templates to stream +their data out as well. (We may go into that a little later.) +Of course, writting the full implementation such that these streams are +interchangable with the standard C++ ostreams is quite a bit more difficult. +In addition, there are a lot of optimizations that this client would benefit +from! +X +<P>As an exercise to the reader (don't you hate those!)
