- /* 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.
