castxml (https://github.com/CastXML/CastXML) may be what you want. It uses the Clang front-end to output an XML representation of a C or C++ parse tree. It is then possible to turn this into what you want. I've used it and seen it used to generate code to do endianess conversion of structures from headers, or RPC code generation for example.

It can be used from Python through pygccxml (https://github.com/CastXML/pygccxml). The name comes from a previous instance, gccxml, based on the GCC front-end.

Both castxml and pygccxml are packaged in Debian and Ubuntu.
