OK, fine, I read longobject.c at last! :)
I found that longobject is a structure like this:
struct _longobject {
struct _object *_ob_next;
struct _object *_ob_prev;
Py_ssize_t ob_refcnt;
struct _typeobject *ob_type;
digit ob_digit[1];
}
And a digit is a 15-item array of C's un

Hello again,
This time I have a simple C question!
As you know, _PyLong_New returns the result of PyObject_NEW_VAR. I
found PyObject_NEW_VAR in objimpl.h header file. But I can't
understand the last line :( Here's the code:
#define PyObject_NEW_VAR(type, typeobj, n) \
( (type *) PyObject_InitVar(

Oh, I didn't see long_as_number before. I'm reading it. That was very
helpful, thanks.

Hello,
I'm reading about implementation of long ints in Python. I downloaded
the source code of CPython and will read the longobject.c, but from
where I should start reading this file? I mean which function is the
first?
Anyone can help?
Thanks

Oh... I got it! :)
I found this line in ctypes.h:
#define Py_TYPE(q) = ((PyObject *)(q))->ob_next;
So those lines are trying to set the blocks type from rear to front.
But I still don't know why after the while (when q is equal to p), the
Py_TYPE(q) set to NULL!

Hello community,
I'm reading the CPython interpreter source code,
first, if you have something that I should know for better reading
this source code, I would much appreciate that :)
second, in intobject.c file, I read the following code in
fill_free_list function that I couldn't understand:
