/* CObjects are marked Pending Deprecation as of Python 2.7. The full schedule for 2.x is as follows: - CObjects are marked Pending Deprecation in Python 2.7. - CObjects will be marked Deprecated in Python 2.8 (if there is one). - CObjects will be removed in Python 2.9 (if there is one). Additionally, for the Python 3.x series: - CObjects were marked Deprecated in Python 3.1. - CObjects will be removed in Python 3.2. You should switch all use of CObjects to capsules. Capsules have a safer and more consistent API. For more information, see Include/pycapsule.h, or read the "Capsules" topic in the "Python/C API Reference Manual". Python 2.7 no longer uses CObjects itself; all objects which were formerly CObjects are now capsules. Note that this change does not by itself break binary compatibility with extensions built for previous versions of Python--PyCObject_AsVoidPtr() has been changed to also understand capsules. */ /* original file header comment follows: */ /* C objects to be exported from one extension module to another.
