Mixing the FFI and the classic C API is not a good idea. You
shouldn't ever need to deal with FFI types in the classic C API.
Say, if you want to access an FFI struct, then declare a C
function and call it via the FFI with the struct as an argument.
The C function will receive a pointer to the struct. No wrapper
code necessary.
