+ Return a C :ctype:`long` representation of the contents of
+ *pylong*. If *pylong* is greater than :const:`LONG_MAX` or less
+ than :const:`LONG_MIN`, set `*overflow` to ``1`` or ``-1``,
+ respectively, and return ``-1``; otherwise, set `*overflow` to
+ ``0``. If any other exception occurs (for example a TypeError or
+ MemoryError), then ``-1`` will be returned and ``*overflow`` will
+ be ``0``.
