You could examine the parent process IDs they should lead to a shel whose parent will either be a console or an x application.

You could use "ttyname()". This returns the path to the terminal connected to a filedescriptor. For consoles, this will be something like "/dev/tty1", for a xterm it will return somthing like /dev/pts/1
