[C++-sig] How to convert a Python Tuple into a C/C++ array?

[aashish at iastate.edu]

 I didn't use Python C API but I know that in boost.python its really
straight forward.

Well C++-sig is  boost.python forum (I guess, I am new to here :) )  ..
you can try python forum for your question and probably they can give you
a better answer.

Hope this helps.
