rffi.CStruct() is used to declare the RPython interface for structs that are originally defined in C. You can use lltype.Struct(), but it's not recommended in your case because lltype.Struct() is meant to define structs in RPython where you *don't* need a precise C-level struct; for example, lltype.Struct() could rename and reorder the fields in C if it is more efficient. We don't have a direct way to declare the struct in RPython but also force it to generate exactly the C struct declaration you want, because we never needed it. You need to use rffi.CStruct() and write the struct in the .h file manually too. > 1. If I have to, how would I do that, is there any example of embedding > rpython into something? Not really. Look maybe at tests using rpython.rlib.entrypoint, like rpython/translator/c/test/test_genc:test_entrypoints.
