Yes, that could explain why the stderr line appears at different places and sometimes even gets placed correctly. It does not neccessarily explain why the effect happens at all, IMHO. > It turned out that I forgot to introduce a flag pro_errortoout in > tmseprocess.options which feeds the stdout pipe to stdout and stderror in Interesting :-( This "explanation" tells me absolutely nothing - I cannot imagine by any means what an additional option flag might effect towards correctly feeding output from different sources to a single destination. And above that, your further "explanation" sounds backwards to me... The name seems to imply that stderr output wasn't displayed before - but it _was_, it just came out misplaced at times. So I _do_ wonder what this flag might really effect/affect? To me, as a user, that flag only increases the size of your code "universe" (the set of possible configurations) by a factor of two, making maintenance more complex by a factor of 2^^((configuration space size)^^2). (I'm just about building a "small" [micro-] controller program for some appliance that the customer wanted to be very broadly applicable, even covering two quite distinct use cases. Even though it's not yet finished, they already lamented about how difficult it was testing it thouroughly enough to find out what's still wrong or not compliant with their wishes...) > Minoshi, does activating pro_errortoout help? I'd like to know too... -- (Weitergabe von Adressdaten, Telefonnummern u.ä. ohne Zustimmung nicht gestattet, ebenso Zusendung von Werbung oder ähnlichem) ----------------------------------------------------------- Mit freundlichen Grüßen, S.
