Guido van Rossumcaa63801995-01-12 11:45:45 +00005PyIntObject represents a (long) integer. This is an immutable object;
Guido van Rossum85a5fbb1990-10-14 12:07:46 +00006an integer cannot change its value after creation.
7
8There are functions to create new integer objects, to test an object
9for integer-ness, and to get the integer value. The latter functions
Guido van Rossumcaa63801995-01-12 11:45:45 +000010returns -1 and sets errno to EBADF if the object is not an PyIntObject.
Guido van Rossum85a5fbb1990-10-14 12:07:46 +000011None of the functions should be applied to nil objects.

Guido van Rossumcaa63801995-01-12 11:45:45 +000013The type PyIntObject is (unfortunately) exposed here so we can declare
Armin Rigo89a39462004-10-28 16:32:00 +000014_Py_TrueStruct and _Py_ZeroStruct in boolobject.h; don't use this.
