I'm getting confused by the behaviour of INTERACTIVE-STREAM-P,
I'm trying to use it in the following manner
(if (interactive-stream-p *error-output*)
... output progress messages)
However, it is always saying *error-output* is interactive, even when I
redirect to a file or pipe, ie,
clisp -x '(interactive-stream-p *error-output*)' >& foo
puts T into the output file. I get the same result when I use *standard-output* or
If I do
(setf *error-output* (open "foo" :direction :output))
I get NIL, as expected.
What am I doing wrong?
I'm running 17April96 version compiled (by me) for Solaris2.5.
I notice the NEWS file contains the 22June1994 comment
* The function INTERACTIVE-STREAM-P knows that if the terminal stream is
referring to a regular file (via input redirection) it is not interactive.
Implying that it should work.
