hello
I am calling a terra function from C and using the returned value later in
the C source.
The terra function is
terra testme(a:Rbase.SEXP)
var a1 : RealVector = rv.salloc():init(a)
return(a1)
end
where
struct RealVector(R.Object)
{
_sexp : R.SEXP;
_ptr : &double;
_length : uint64;
}
(neither the salloc or init do any memory allocation)
So when i call testme from C, i get a CDATA data structure(
cdata<struct RealVector_1 *>: ). I
imagine
const void *p = lua_topointer (L,-1); // L is LuaState after
'testme' returns
a = *((SEXP *)p);
I imagine 'a' will now point to the '_sexp' member of the returned
struct.
Is this expectation correct? Or do terra structs get padded?
Regards
Saptarshi
