Hello,
I'm creating a GNU Radio OOT module in C++ language, in which I instantiate
an osmosdr source. The syntax is : osmosdr::source ::sptr m_source =
osmosdr::source::make();
I also implement other blocks in my design.
In CMakeLists.txt file, I specify all these components:

You can't actually control it, but you can set a minimum number, yes.

look for the thing that initiates your tagging, and add new tags every

Hmm ok, I feel like perhaps I've misunderstood some fundamental mechanic of
GNURadio.. is it within my power to define the exact number of samples that
should be available on the next call to the work function of e.g. a sync

Hi,
I suppose not - I just figured that using a tagged stream block would be
useful since then I'd be able to iterate over the entire packet in one work

Hi Marcus,
Aha, that explains it.. bummer! Perhaps you could advise me on an

I must admit that I don't remember whether the TSB block base was
correctly wrapped for Python (darn it, first I write something, and
then you find a glaring counterexample); in fact, there's not a single
test case for that in the main GNU Radio tree, which probably means
"no".
