Hassles with fprintf

[Hans H. Huebner]

Hello,

lately I ran into a problem while working at my sendmail port for XENIX.
Although sendmail runs fine so far, it always gave the bogus error message
"Not a character device" (ENOTTY) whenever something went wrong. I was able
to track down the producer of this errno value to be fprintf, and I
wondered if anyone here knows what's happening, since fprintf isn't
supposed to set errno to ENOTTY as far as i know. I have now kludged around
the problem with a fake fprintf which preserves the old errno, but I don't
think that's a good solution. Any clues ?

(Environment: Xenix 2.2 Development & O-System, generic AT klone)

Please respond directly since I don't normally read these groups due to
their massive volume.

	Thanks,
		Hans
