[stdlib-sig] ctypes or struct from an h file

Is there a way that Python and C can have a shared definition for a binary data structure?

It could be nice if: 1. struct or ctypes had a function that could parse a .h/.c/.cpp file to auto-generate constructors or 2. a ctypes definition could be exported to a .h file.

So my question is - is there a way to do this in the std-lib or even pypi?

ps If this doesn't exist, then I'm probably going to open a project and would like some tips/ideas.
