This C function

typedef struct {
    PyObject *in;
    PyObject *out;
} ufunc_full_args;

static int
PyUFunc_GenericFunctionInternal(PyUFuncObject *ufunc, PyArrayObject **op,
        ufunc_full_args full_args, PyObject *type_tup, PyObject *extobj,
        NPY_CASTING casting, NPY_ORDER order, npy_bool subok,
