/* 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.
