Take a look at gr.feval_xx class: http://gnuradio.org/trac/browser/gnuradio/trunk/gnuradio-core/src/lib/general/gr_feval.h It defines a function 'eval' that can be called either from C++ or from Python. In Python you can subclass this and override the eval function with whatever you want. When the function is called from C++, control flow passes to the Python interpreter to evaluate the function and return. I haven't used it myself, but you can get a good feel for what is possible by looking at the QA code for the block at: http://gnuradio.org/trac/browser/gnuradio/trunk/gnuradio-core/src/python/gnuradio/gr/qa_feval.py Johnathan Corgan, AE6HO [EMAIL PROTECTED] _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
