12 # This subtype of PyObject represents a Python long integer object.
14 # PyTypeObject PyLong_Type
16 # This instance of PyTypeObject represents the Python long integer
17 # type. This is the same object as long and types.LongType.
19 bint PyLong_Check(object p)
20 # Return true if its argument is a PyLongObject or a subtype of PyLongObject.
22 bint PyLong_CheckExact(object p)
23 # Return true if its argument is a PyLongObject, but not a subtype of PyLongObject.
25 object PyLong_FromLong(long v)
26 # Return value: New reference.
27 # Return a new PyLongObject object from v, or NULL on failure.
29 object PyLong_FromUnsignedLong(unsigned long v)
30 # Return value: New reference.
31 # Return a new PyLongObject object from a C unsigned long, or NULL on failure.
33 object PyLong_FromLongLong(PY_LONG_LONG v)
34 # Return value: New reference.
35 # Return a new PyLongObject object from a C long long, or NULL on failure.
37 object PyLong_FromUnsignedLongLong(uPY_LONG_LONG v)
38 # Return value: New reference.
39 # Return a new PyLongObject object from a C unsigned long long, or NULL on failure.
41 object PyLong_FromDouble(double v)
42 # Return value: New reference.
43 # Return a new PyLongObject object from the integer part of v, or NULL on failure.
45 object PyLong_FromString(char *str, char **pend, int base)
46 # Return value: New reference.
47 # Return a new PyLongObject based on the string value in str,
48 # which is interpreted according to the radix in base. If pend is
49 # non-NULL, *pend will point to the first character in str which
50 # follows the representation of the number. If base is 0, the
51 # radix will be determined based on the leading characters of str:
52 # if str starts with '0x' or '0X', radix 16 will be used; if str
53 # starts with '0', radix 8 will be used; otherwise radix 10 will
54 # be used. If base is not 0, it must be between 2 and 36,
55 # inclusive. Leading spaces are ignored. If there are no digits,
56 # ValueError will be raised.
58 object PyLong_FromUnicode(Py_UNICODE *u, Py_ssize_t length, int base)
59 # Return value: New reference.
60 # Convert a sequence of Unicode digits to a Python long integer
61 # value. The first parameter, u, points to the first character of
62 # the Unicode string, length gives the number of characters, and
63 # base is the radix for the conversion. The radix must be in the
64 # range [2, 36]; if it is out of range, ValueError will be
67 object PyLong_FromVoidPtr(void *p)
68 # Return value: New reference.
69 # Create a Python integer or long integer from the pointer p. The
70 # pointer value can be retrieved from the resulting value using
71 # PyLong_AsVoidPtr(). If the integer is larger than LONG_MAX, a
72 # positive long integer is returned.
74 long PyLong_AsLong(object pylong) except? -1
75 # Return a C long representation of the contents of pylong. If
76 # pylong is greater than LONG_MAX, an OverflowError is raised.
78 unsigned long PyLong_AsUnsignedLong(object pylong) except? -1
79 # Return a C unsigned long representation of the contents of
80 # pylong. If pylong is greater than ULONG_MAX, an OverflowError is
83 PY_LONG_LONG PyLong_AsLongLong(object pylong) except? -1
84 # Return a C long long from a Python long integer. If pylong
85 # cannot be represented as a long long, an OverflowError will be
88 uPY_LONG_LONG PyLong_AsUnsignedLongLong(object pylong) except? -1
89 #unsigned PY_LONG_LONG PyLong_AsUnsignedLongLong(object pylong)
90 # Return a C unsigned long long from a Python long integer. If
91 # pylong cannot be represented as an unsigned long long, an
92 # OverflowError will be raised if the value is positive, or a
93 # TypeError will be raised if the value is negative.
95 unsigned long PyLong_AsUnsignedLongMask(object io) except? -1
96 # Return a C unsigned long from a Python long integer, without
97 # checking for overflow.
99 uPY_LONG_LONG PyLong_AsUnsignedLongLongMask(object io) except? -1
100 #unsigned PY_LONG_LONG PyLong_AsUnsignedLongLongMask(object io)
101 # Return a C unsigned long long from a Python long integer,
102 # without checking for overflow.
104 double PyLong_AsDouble(object pylong) except? -1.0
105 # Return a C double representation of the contents of pylong. If
106 # pylong cannot be approximately represented as a double, an
107 # OverflowError exception is raised and -1.0 will be returned.
109 void* PyLong_AsVoidPtr(object pylong) except? NULL
110 # Convert a Python integer or long integer pylong to a C void
111 # pointer. If pylong cannot be converted, an OverflowError will be
112 # raised. This is only assured to produce a usable void pointer
113 # for values created with PyLong_FromVoidPtr(). For values outside
114 # 0..LONG_MAX, both signed and unsigned integers are acccepted.
