/* 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 in boolobject.h; don't use this. */ #ifndef Py_INTOBJECT_H #define Py_INTOBJECT_H #ifdef __cplusplus extern "C" { #endif typedef struct { PyObject_HEAD long ob_ival; } PyIntObject; PyAPI_DATA(PyTypeObject) PyInt_Type; #define PyInt_Check(op) \ PyType_FastSubclass(Py_TYPE(op), Py_TPFLAGS_INT_SUBCLASS) #define PyInt_CheckExact(op) (Py_TYPE(op) == &PyInt_Type) #define _PyAnyInt_Check(op) (PyInt_Check(op) || PyLong_Check(op)) #define _PyAnyInt_CheckExact(op) (PyInt_CheckExact(op) || PyLong_CheckExact(op)) PyAPI_FUNC(PyObject *) PyInt_FromString(char*, char**, int); #ifdef Py_USING_UNICODE PyAPI_FUNC(PyObject *) PyInt_FromUnicode(Py_UNICODE*, Py_ssize_t, int); #endif PyAPI_FUNC(PyObject *) PyInt_FromLong(long); PyAPI_FUNC(PyObject *) PyInt_FromSize_t(size_t); PyAPI_FUNC(PyObject *) PyInt_FromSsize_t(Py_ssize_t); PyAPI_FUNC(long) PyInt_AsLong(PyObject *); PyAPI_FUNC(Py_ssize_t) PyInt_AsSsize_t(PyObject *); PyAPI_FUNC(int) _PyInt_AsInt(PyObject *); PyAPI_FUNC(unsigned long) PyInt_AsUnsignedLongMask(PyObject *); #ifdef HAVE_LONG_LONG PyAPI_FUNC(unsigned PY_LONG_LONG) PyInt_AsUnsignedLongLongMask(PyObject *); #endif PyAPI_FUNC(long) PyInt_GetMax(void); /* Macro, trading safety for speed */ #define PyInt_AS_LONG(op) (((PyIntObject *)(op))->ob_ival) /* These aren't really part of the Int object, but they're handy; the protos * are necessary for systems that need the magic of PyAPI_FUNC and that want * to have stropmodule as a dynamically loaded module instead of building it * into the main Python shared library/DLL.
