[Discuss-gnuradio] stdout and stderr

[cswiger]

Does the gnuradio / python output conform to usual unix
stdout and stderr - that is, normal status and informational
output go to stdout, while errors like USRP and Audio
over/under run go to stderr?

A text mode radio outputs status and takes user control
on the command line, but gets interference from the usual
out-of-sync hardware clocks aUaUaUaUuOuO  etc.  If I run
it with

$ ssb_rx.py -f3938e3 2>/dev/null

then I get NO output, even from the command prompt, altho
user commands get in ok.

Anyway, it would be nice to seperate stdout and stderr streams.

I can turn off aUaUaUaU by commenting out the printf statements
in the code to turn off the annoying chatter, but then you lose
an important indication of something really wrong (like truncated
fractional decimation) in other cases.
