Hi! Is there a way to detect your login tty? ttyname(3) only gives me the name of the pty of the current window or rlogin session. I know that I can find it through wtmp, but this is not acceptable since then there might be a lot of I/O involved which would slow down the application too much. Also one can never be sure that a wtmp file exists. Anyone any idea??
