+
+   Return a C :ctype:`long long` representation of the contents of
+   *pylong*.  If *pylong* is greater than :const:`PY_LLONG_MAX` or less
+   than :const:`PY_LLONG_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``.
