You introduce a strong point with the issue moving structs over the barrier. When I do it, I create constructor functions in C, and only send pointers over the bridge between the non-C and C. I'm happy to do this, but recognise that it is boilerplatey, and should be seen as a different tradeoff choice rather than a trivial alternative. Agree regarding C++ ABI also. I don't have much experience with C++. My usual approach is to use C for system calls and bare-minimum surrounds, and then use the wrapping approaches described above to get to a high-level language. This is why the struct issue didn't come to mind for me.
