Wrap a function returning an object

[Hleb]

Hi!

I have some methods returning objects instead of pointers, e.g. (simplified)

=======

class Selection{void*ptr; int type;};

Selection find(const char*);

=======

If I use (define-c Selection find (string)) the generated code assumes that a pointer is returned: sexp_make_cpointer(ctx, sexp_unbox_fixnum(sexp_opcode_return_type(self)), find(sexp_string_data(arg0)), SEXP_FALSE, 0);

How to properly handle such cases? My current attempt is

========

auto *sel = static_cast<Selection*>(sexp_alloc(ctx, sizeof(Selection)));
*sel = find(s);
return sexp_make_cpointer(ctx, sexp_type_tag(SelectionType), sel, nullptr, 0);

========

But i'm not sure.
