[Discuss-gnuradio] Developing with C++ but not python

[Gong Zhang]

Hi,
   I think python file means data go downstream without interacting 
with other data stream.And I have seen several example writen in c++ and 
they all contain a gr_top_block which makes them similar to python 
files.Any body have the experience developing in c++?And what you think 
is the major difficulity(except more effort) compared to python?
   Thanks.
