Thank you for answering a question I didn't ask! The current
version of vfxlin has changed! The question is how do I
determine if a program is running in a terminal session or is
detached in some way, e.g. by using & at the end of the command
line? I need need to make this distinction in order to choose
between I/O to the term/xterm device or launch a GUI console.
Under Kubuntu 9.04 at least, trying to open /dev/tty succeeds in
both cases and fds 0,1,2 return true from isatty(). Similarly,
ttyname() returns a name.
