[Discuss-gnuradio] Fwd: Fwd: What value is in in[noutput_items+1]?

Thanks Sylvain and Nathan.  As soon as you mentioned set_history(N) is N-1 and how the data was laid out, everything made sense.  Made a quick fix in my code and the anomaly's gone.

Thanks!

First, set_history(2) means there will be 1 old sample, not two. (yeah
go figure ... but the default value is '1' and means "no history").

So, if noutput_items = 8192

in[0] = history[0]
in[1] = new_sample[0]
...
in[8192] = new_sample[8191]


Cheers,
