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.

False and True are special intobjects used by Boolean expressions.
|
|
All values of type Boolean must point to either of these; but in
|
|
contexts where integers are required they are integers (valued 0 and 1).
|
|
Hope these macros don't conflict with other people's.
|
|
|
|
Don't forget to apply Py_INCREF() when returning True or False!!!
