    If ``result`` is smaller than ``0``, it is interpreted as negative error
    code, and an appropriate exception is raised:

    - ``-ENOMEM`` raises a :exc:`~exceptions.MemoryError`
    - ``-EOVERFLOW`` raises a :exc:`~exceptions.OverflowError`
    - all other error codes raise :exc:`~exceptions.EnvironmentError`

    If result is greater or equal to ``0``, it is returned unchanged.
