Hi all,
I'm trying to port my posix_ipc extension to Python 3, and I'm
confused by the documentation for PyObject_HEAD and PyObject_VAR_HEAD.
My understanding is that a PyObject-derived type should begin its
PyTypeObject struct with PyObject_HEAD and a PyVarObject-derived type
with PyObject_VAR_HEAD. the documentation says of PyVarObject, "This
type does not often appear in the Python/C API."
http://docs.python.org/3.1/c-api/structures.html#PyVarObject
The doc also says that …
[View More]PyObject_VAR_HEAD, "is used when declaring new
types which represent objects with a length that varies from instance
to instance."
http://docs.python.org/3.1/c-api/structures.html#PyObject_VAR_HEAD
I assumed, then, that PyObject_VAR_HEAD would also appear
infrequently, but that's not the case at all. In fact, I can't find
PyObject_HEAD used at all in the Python 3.1.1 source code, whereas
PyObject_VAR_HEAD is used hundreds of times, including for objects
that don't have a length (like the float type, for instance).
Is the documentation wrong, or am I misreading it? Suggestions
appreciated.
THanks
