pointer for success, and ``NULL`` for failure. But if you use an integer return converter,
all integers are valid. How can Argument Clinic detect an error? Its solution: each return

that value, and an error has been set (``PyErr_Occurred()`` returns a true
-value), then the generated code will propogate the error. Otherwise it will
