/* Integer object interface */
/*
PyIntObject represents a (long) integer. This is an immutable object;
1990-10-14 09:07:46 -03:00
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.
1990-10-14 09:07:46 -03:00
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.
