/* 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 below; don't use this. |
