I've had some success doing the meta programming in python, which generates .cpp (since the preprocessor does some expansion, it's not C++) files that I include from and .h file which I include in C code. It's harder to go the other way. It lets you basically modify only the python source and then have the same names for structs (classes in python) in both languages. But then I realized it was all pretty complicated. So I started using ctypes instead. That way I only wrote it once in a header file. The only real limitation when using cpython was that I could only include a maximum of one other struct in each struct, so sometimes the C header files were a bit strangely written.
