+Long Integer Objects
+--------------------
+
+.. index:: object: long integer
+
+
+.. ctype:: PyLongObject
+
+ This subtype of :ctype:`PyObject` represents a Python long integer object.
+
+
+.. cvar:: PyTypeObject PyLong_Type
+
+ .. index:: single: LongType (in modules types)
+
+ This instance of :ctype:`PyTypeObject` represents the Python long integer type.
+ This is the same object as ``long`` and ``types.LongType``.
+
+
+.. cfunction:: int PyLong_Check(PyObject *p)
+
+ Return true if its argument is a :ctype:`PyLongObject` or a subtype of
+ :ctype:`PyLongObject`.
+
+ .. versionchanged:: 2.2
+ Allowed subtypes to be accepted.
+
+
+.. cfunction:: int PyLong_CheckExact(PyObject *p)
+
+ Return true if its argument is a :ctype:`PyLongObject`, but not a subtype of
+ :ctype:`PyLongObject`.
+
+ .. versionadded:: 2.2
+
+
+.. cfunction:: PyObject* PyLong_FromLong(long v)
+
+ Return a new :ctype:`PyLongObject` object from *v*, or *NULL* on failure.
+
+
+.. cfunction:: PyObject* PyLong_FromUnsignedLong(unsigned long v)
+
+ Return a new :ctype:`PyLongObject` object from a C :ctype:`unsigned long`, or
+ *NULL* on failure.
+
+
+.. cfunction:: PyObject* PyLong_FromSsize_t(Py_ssize_t v)
+
+ Return a new :ctype:`PyLongObject` object from a C :ctype:`Py_ssize_t`, or
+ *NULL* on failure.
+
+ .. versionadded:: 2.5
+
+
+.. cfunction:: PyObject* PyLong_FromSize_t(size_t v)
+
+ Return a new :ctype:`PyLongObject` object from a C :ctype:`size_t`, or
+ *NULL* on failure.
+
+ .. versionadded:: 2.5
+
+
+.. cfunction:: PyObject* PyLong_FromLongLong(PY_LONG_LONG v)
+
+ Return a new :ctype:`PyLongObject` object from a C :ctype:`long long`, or *NULL*
+ on failure.
+
+
+.. cfunction:: PyObject* PyLong_FromUnsignedLongLong(unsigned PY_LONG_LONG v)
+
+ Return a new :ctype:`PyLongObject` object from a C :ctype:`unsigned long long`,
+ or *NULL* on failure.
+
+
+.. cfunction:: PyObject* PyLong_FromDouble(double v)
+
+ Return a new :ctype:`PyLongObject` object from the integer part of *v*, or
+ *NULL* on failure.
+
+
+.. cfunction:: PyObject* PyLong_FromString(char *str, char **pend, int base)
+
+ Return a new :ctype:`PyLongObject` based on the string value in *str*, which is
+ interpreted according to the radix in *base*. If *pend* is non-*NULL*,
+ ``*pend`` will point to the first character in *str* which follows the
+ representation of the number. If *base* is ``0``, the radix will be determined
+ based on the leading characters of *str*: if *str* starts with ``'0x'`` or
+ ``'0X'``, radix 16 will be used; if *str* starts with ``'0'``, radix 8 will be
+ used; otherwise radix 10 will be used. If *base* is not ``0``, it must be
+ between ``2`` and ``36``, inclusive. Leading spaces are ignored. If there are
+ no digits, :exc:`ValueError` will be raised.
+
+
+.. cfunction:: PyObject* PyLong_FromUnicode(Py_UNICODE *u, Py_ssize_t length, int base)
+
+ Convert a sequence of Unicode digits to a Python long integer value. The first
+ parameter, *u*, points to the first character of the Unicode string, *length*
+ gives the number of characters, and *base* is the radix for the conversion. The
+ radix must be in the range [2, 36]; if it is out of range, :exc:`ValueError`
+ will be raised.
+
+ .. versionadded:: 1.6
+
+
+.. cfunction:: PyObject* PyLong_FromVoidPtr(void *p)
+
+ Create a Python integer or long integer from the pointer *p*. The pointer value
+ can be retrieved from the resulting value using :cfunc:`PyLong_AsVoidPtr`.
+
+ .. versionadded:: 1.5.2
+
+ .. versionchanged:: 2.5
+ If the integer is larger than LONG_MAX, a positive long integer is returned.
+
+
+.. cfunction:: long PyLong_AsLong(PyObject *pylong)
+
+ .. index::
+ single: LONG_MAX
+ single: OverflowError (built-in exception)
+
+ Return a C :ctype:`long` representation of the contents of *pylong*. If
+ *pylong* is greater than :const:`LONG_MAX`, an :exc:`OverflowError` is raised
+ and ``-1`` will be returned.
+
+
+.. cfunction:: Py_ssize_t PyLong_AsSsize_t(PyObject *pylong)
+
+ .. index::
+ single: PY_SSIZE_T_MAX
+ single: OverflowError (built-in exception)
+
+ Return a C :ctype:`Py_ssize_t` representation of the contents of *pylong*. If
+ *pylong* is greater than :const:`PY_SSIZE_T_MAX`, an :exc:`OverflowError` is raised
+ and ``-1`` will be returned.
+
+ .. versionadded:: 2.5
+
+
+.. cfunction:: unsigned long PyLong_AsUnsignedLong(PyObject *pylong)
+
+ .. index::
+ single: ULONG_MAX
+ single: OverflowError (built-in exception)
+
+ Return a C :ctype:`unsigned long` representation of the contents of *pylong*.
+ If *pylong* is greater than :const:`ULONG_MAX`, an :exc:`OverflowError` is
+ raised.
+
+
+.. cfunction:: PY_LONG_LONG PyLong_AsLongLong(PyObject *pylong)
+
+ Return a C :ctype:`long long` from a Python long integer. If *pylong* cannot be
+ represented as a :ctype:`long long`, an :exc:`OverflowError` will be raised.
+
+ .. versionadded:: 2.2
+
+
+.. cfunction:: unsigned PY_LONG_LONG PyLong_AsUnsignedLongLong(PyObject *pylong)
+
+ Return a C :ctype:`unsigned long long` from a Python long integer. If *pylong*
+ cannot be represented as an :ctype:`unsigned long long`, an :exc:`OverflowError`
+ will be raised if the value is positive, or a :exc:`TypeError` will be raised if
+ the value is negative.
+
+ .. versionadded:: 2.2
+
+
+.. cfunction:: unsigned long PyLong_AsUnsignedLongMask(PyObject *io)
+
+ Return a C :ctype:`unsigned long` from a Python long integer, without checking
+ for overflow.
+
+ .. versionadded:: 2.3
+
+
+.. cfunction:: unsigned PY_LONG_LONG PyLong_AsUnsignedLongLongMask(PyObject *io)
+
+ Return a C :ctype:`unsigned long long` from a Python long integer, without
+ checking for overflow.
+
+ .. versionadded:: 2.3
+
+
+.. cfunction:: double PyLong_AsDouble(PyObject *pylong)
+
+ Return a C :ctype:`double` representation of the contents of *pylong*. If
+ *pylong* cannot be approximately represented as a :ctype:`double`, an
+ :exc:`OverflowError` exception is raised and ``-1.0`` will be returned.
+
+
+.. cfunction:: void* PyLong_AsVoidPtr(PyObject *pylong)
+
+ Convert a Python integer or long integer *pylong* to a C :ctype:`void` pointer.
+ If *pylong* cannot be converted, an :exc:`OverflowError` will be raised. This
+ is only assured to produce a usable :ctype:`void` pointer for values created
+ with :cfunc:`PyLong_FromVoidPtr`.
+
+ .. versionadded:: 1.5.2
+
+ .. versionchanged:: 2.5
+ For values outside 0..LONG_MAX, both signed and unsigned integers are accepted.
