Hi Marcus, 

what do you mean by "run to completion" ?

best,

Hi Martin, 

Thank you so much, :) 

The last example you mentioned, gr-uhd/examples/c++/tags_demo.cc, this will help me!! 

It's interesting example. 

Thank you.

It's better to say in this way: *how could I use stop(), start(),
lock(), unlock() of the topblock methods? Is there any example of them?*

        Thank you martin,

        I saw examples before, but all of them used blocks in the main
        of the
        c++ code. I wanna have a class derived from topblock of gnuradio
        and put
        the blocks' connections in it. Then in the main of the program,
        run or
        stop the topblock.

        Can you give a part of the code in c++ ?


    If it's not in the examples, I'm not sure what you exactly want.
    Also, please use the mailing list for these kinds of requests.

                 Hi everybody,

                 I was wonder why I can't make a class of topblock in
        c++ like in
                 python
                 as said here:

        http://gnuradio.org/redmine/____projects/gnuradio/wiki/____TutorialsWritePythonApplicatio____ns
        <http://gnuradio.org/redmine/__projects/gnuradio/wiki/__TutorialsWritePythonApplicatio__ns>

        <http://gnuradio.org/redmine/__projects/gnuradio/wiki/__TutorialsWritePythonApplicatio__ns
        <http://gnuradio.org/redmine/projects/gnuradio/wiki/TutorialsWritePythonApplications>>

                 Then I think, I can control the flowgraph, start or
        stop it ,
                 disconnect
                 or connect blocks and anything else .

                 Any idea?


             It's pretty much the same, just in C++.
             Have a look at the c++ examples in the source tree, that'll
        get you
             started.
