Hi, I just want to use NA_get1_Int64 etc but I couldn't find a way to 'cleanly' find out about the size of an array, i.e. I always have to access raw fields in the PyArrayObject structure like: PyArrayObject* a; if (a->nd == 2) { if (a->dimensions[0] == m && b->dimensions[1] == n) ... Is this the intended way ? I hope not... Best, Soeren
