[Discuss-gnuradio] SWIG Typemap for Two-way Conversion Between Python Stringand (char*, int) in C++

[Jeremy Chew]

Hi,

I've read that we can specify a typemap to change an input Python string to
(char*,int) in C++.

How do we specify a typemap for a C++ extension that also converts such
strings from C++ to Python? I want to have C++ calls that receive strings 
from Python code as well as C++ calls that pass strings to Python code.

Thanks,
Jeremy
