The second argument points to the (optional) object for that you are
creating the view. The code in Object/stringobject.c is a good example:

static int
string_buffer_getbuffer(PyStringObject *self, Py_buffer *view, int flags)
{
        return PyBuffer_FillInfo(view, (PyObject*)self,
                                 (void *)self->ob_sval, Py_SIZE(self),
                                 1, flags);
}
