+    # PyLongObject
+    #
+    # This subtype of PyObject represents a Python long integer object.
+
+    # PyTypeObject PyLong_Type
+    #
+    # This instance of PyTypeObject represents the Python long integer
+    # type. This is the same object as long and types.LongType.
+
+    bint PyLong_Check(object p)
+    # Return true if its argument is a PyLongObject or a subtype of PyLongObject.
+
+    bint PyLong_CheckExact(object p)
+    # Return true if its argument is a PyLongObject, but not a subtype of PyLongObject.
+
+    object PyLong_FromLong(long v)
+    # Return value: New reference.
+    # Return a new PyLongObject object from v, or NULL on failure.
+
+    object PyLong_FromUnsignedLong(unsigned long v)
+    # Return value: New reference.
+    # Return a new PyLongObject object from a C unsigned long, or NULL on failure.
+
+    object PyLong_FromLongLong(PY_LONG_LONG v)
+    # Return value: New reference.
+    # Return a new PyLongObject object from a C long long, or NULL on failure.
+
+    object PyLong_FromUnsignedLongLong(uPY_LONG_LONG v)
+    # Return value: New reference.
+    # Return a new PyLongObject object from a C unsigned long long, or NULL on failure.
+
+    object PyLong_FromDouble(double v)
+    # Return value: New reference.
+    # Return a new PyLongObject object from the integer part of v, or NULL on failure.
+
+    object PyLong_FromString(char *str, char **pend, int base)
+    # Return value: New reference.
+    # Return a new 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,
+    # ValueError will be raised.
+
+    object PyLong_FromUnicode(Py_UNICODE *u, Py_ssize_t length, int base)
+    # Return value: New reference.
+    # 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, ValueError will be
+    # raised.
+
+    object PyLong_FromVoidPtr(void *p)
+    # Return value: New reference.
+    # Create a Python integer or long integer from the pointer p. The
+    # pointer value can be retrieved from the resulting value using
+    # PyLong_AsVoidPtr().  If the integer is larger than LONG_MAX, a
+    # positive long integer is returned.

+    # raised.
+
+    PY_LONG_LONG PyLong_AsLongLong(object pylong) except? -1
+    # Return a C long long from a Python long integer. If pylong
+    # cannot be represented as a long long, an OverflowError will be

+
+    uPY_LONG_LONG PyLong_AsUnsignedLongLong(object pylong) except? -1

+    # TypeError will be raised if the value is negative.
+

+    # checking for overflow.
+
+    uPY_LONG_LONG PyLong_AsUnsignedLongLongMask(object io) except? -1
+    #unsigned PY_LONG_LONG PyLong_AsUnsignedLongLongMask(object io)
+    # Return a C unsigned long long from a Python long integer,
+    # without checking for overflow.
+
+    double PyLong_AsDouble(object pylong) except? -1.0
+    # Return a C double representation of the contents of pylong. If
+    # pylong cannot be approximately represented as a double, an
+    # OverflowError exception is raised and -1.0 will be returned.
+
+    void* PyLong_AsVoidPtr(object pylong) except? NULL
+    # Convert a Python integer or long integer pylong to a C void
+    # pointer. If pylong cannot be converted, an OverflowError will be
+    # raised. This is only assured to produce a usable void pointer
+    # for values created with PyLong_FromVoidPtr(). For values outside
+    # 0..LONG_MAX, both signed and unsigned integers are acccepted.
