Dear Marcus,
Thanks for thorough explanation.
Let me summarize the information, as below.
Correct me if I am wrong.
1). For sink block derived from gr::sync_block, its work() function should
return noutput_items,
even though sink block doesn't produce any output.
This is a norm.
2)

Yes, it will.
The GNU Radio scheduler calls your block's work() function whenever it
needs new data.
Anyway, this is a very basic principle of GR; I recommend working
through the "creating an OOT module" tutorial, it's really great!
Greetings,
Marcus

Hi all,
First, I like to thank everybody at the FOSDEM SDR devroom today. I
really really learned a lot today!
I want to try to use GR for a session on "how dooes a 433 Mhz ISM signal
look like" in our local radio-club. For that, I want to use the live-CD
/ DVD of gnuradio so that peo
Hi Sylvain,
I am lucky to have a new Laptop with i7 Haswell CPU, however you have
written on gr-fosphor homepage that intel does not offer OpenCL for Haswell
on Linux. (Appearantly due to some self cannibalization issue of their
products if done so, as suggested somewhere else on the internet). I

Question:
How to stop the flow graph when this->d_complete == true ?
Return -1 (or WORK_DONE) in your work() function.

Dear Marcus,
At the receiver USRP, does the SBX daughtercard have any mechanism of
phase-lock-loop (PLL) ?
I guess the daughtercard should have it because PLL is essential for
quadrature downconversion.
Please advise, thanks.
