| 5 | PyIntObject represents a (long) integer. This is an immutable object; |
| 6 | an integer cannot change its value after creation. |
| 7 | |
| 8 | There are functions to create new integer objects, to test an object |
| 9 | for integer-ness, and to get the integer value. The latter functions |
| 10 | returns -1 and sets errno to EBADF if the object is not an PyIntObject. |
| 11 | None of the functions should be applied to nil objects. |
| 12 | |
| 13 | The type PyIntObject is (unfortunately) exposed here so we can declare |
| 14 | _Py_TrueStruct and _Py_ZeroStruct in boolobject.h; don't use this. |
