New functions: unsigned long PyInt_AsUnsignedLongMask(PyObject *); unsigned PY_LONG_LONG) PyInt_AsUnsignedLongLongMask(PyObject *); unsigned long PyLong_AsUnsignedLongMask(PyObject *); unsigned PY_LONG_LONG) PyLong_AsUnsignedLongLongMask(PyObject *); New and changed format codes: b unsigned char 0..UCHAR_MAX B unsigned char none ** h unsigned short 0..USHRT_MAX H unsigned short none ** i int INT_MIN..INT_MAX I * unsigned int 0..UINT_MAX l long LONG_MIN..LONG_MAX k * unsigned long none L long long LLONG_MIN..LLONG_MAX K * unsigned long long none Notes: * New format codes. ** Changed from previous "range-and-a-half" to "none"; the range-and-a-half checking wasn't particularly useful. New test test_getargs2.py, to verify all this.

/* Integer object interface */

|

/*
|
|
PyIntObject represents a (long) integer. This is an immutable object;
|
|
an integer cannot change its value after creation.
|
|
|
|
There are functions to create new integer objects, to test an object
|
|
for integer-ness, and to get the integer value. The latter functions
|
|
returns -1 and sets errno to EBADF if the object is not an PyIntObject.
|
|
None of the functions should be applied to nil objects.
|
|
|
|
The type PyIntObject is (unfortunately) exposed here so we can declare
|
|
_Py_TrueStruct and _Py_ZeroStruct below; don't use this.
