So ok, I have to specify headers containing my structs and somehow push it to rpython toolchain, if I got you correctly. 0. Why? This structures are already described in the vm file as a bunch of ffi.CStruct objects. 1. If I have to, how would I do that, is there any example of embedding rpython into something? I saw an example "how to embed PyPy" but it looked a bit too PyPy specific. Thanks
