how to netcat in listen mode prints to stdout when -c option is in use

Question

I put netcat -l -p 80 into terminal. Then open http://localhost/ in web browser. Now netcat shows the header of the request in stdout. All fine.

But if I use netcat with the -c option netcat does not print anymore to stdout.

How can I get netcat -l -p 80 -c uname to print to stdout?

Maybe via the -o file option via file descriptor?
