Re: C++, stdout, and XInetd

Well, I'm not using any special library, really. The way xinetd works is that
it connects stdin to the input stream and stdout to the output of the program
it invokes. So, I'm just using cout to print to the client.

I'm using Qt, so I've even tried using a QFile and QIOStream and opening
stdout, but even when the client disconnects, QFile::isOpen() still reports
true. Very odd.
