| 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. |
