Terminal window device name

[c.pergiel]

I have a simple C program that processes a input either from file or from stdin.

I want to be able to talk to the user (print messages and get keyboard input) even when stdin has been redirected to a file.

I figure a need a device name, but have been unable to find one the will work.

Running in a DOS box under Windows the name "con" works.

I have tried "con", "console", "/dev/console" under Linux, but none of these names work.

Does /dev/tty0 work?

Text-Terminal-HOWTO: Terminal Special Files such as /dev/tty : see section 6.5

Thanks for the suggestion, but no, /dev/tty0 does not work.
I've tried several different names, but no luck so far.
