Try ttyname(3C) which will return a pointer to a null-terminated 
character string of the terminal device associated with the file
descriptor you send it.  So you can do something like

char *tty_ptr, *strrchr(), *ttyname();

	tty_ptr = strrchr(ttyname(0)) + 1;

assuming that the tty's have something like /dev/ttynnn or the
like.
