*pylong* is greater than :const:`LONG_MAX`, raise an :exc:`OverflowError`,
and return -1. Convert non-long objects automatically to long first,
and return -1 if that raises exceptions.
.. cfunction:: long PyLong_AsLongAndOverflow(PyObject *pylong, int* overflow)
Return a C :ctype:`long` representation of the contents of *pylong*. If
*pylong* is greater than :const:`LONG_MAX`, return -1 and
set `*overflow` to 1 (for overflow) or -1 (for underflow).
If an exception is set because of type errors, also return -1.
