The ``structmember.h`` header is deprecated, though it continues to be available and there are no plans to remove it. There are no deprecation warnings. Old code can stay unchanged (unless the extra include and non-namespaced macros bother you greatly). Specifically, no uses in CPython are updated -- that would just be unnecessary churn. The ``structmember.h`` header is deprecated, though it continues to be available and there are no plans to remove it. Its contents are now available just by including ``Python.h``, with a ``Py`` prefix added if it was missing: - `PyMemberDef`, `PyMember_GetOne` and`PyMember_SetOne` - Type macros like `Py_T_INT`, `Py_T_DOUBLE`, etc. (previously ``T_INT``, ``T_DOUBLE``, etc.) - The flags `Py_READONLY` (previously ``READONLY``) and `Py_AUDIT_READ` (previously all uppercase) Several items are not exposed from ``Python.h``: - `T_OBJECT` (use `Py_T_OBJECT_EX`) - `T_NONE` (previously undocumented, and pretty quirky) - The macro ``WRITE_RESTRICTED`` which does nothing. - The macros ``RESTRICTED`` and ``READ_RESTRICTED``, equivalents of `Py_AUDIT_READ`. - In some configurations, ``<stddef.h>`` is not included from ``Python.h``. It should be included manually when using ``offsetof()``. The deprecated header continues to provide its original contents under the original names. Your old code can stay unchanged, unless the extra include and non-namespaced macros bother you greatly. There is discussion on the issue to rename `T_PYSSIZET` to `PY_T_SSIZE` or similar. I chose not to do that -- users will probably copy/paste that with any spelling, and not renaming it makes migration docs simpler.

/* Interface to map C struct members to Python object attributes

*
|
|
* This header is deprecated: new code should not use stuff from here.
|
|
* New definitions are in descrobject.h.
|
|
*
|
|
* However, there's nothing wrong with old code continuing to use it,
|
|
* and there's not much mainenance overhead in maintaining a few aliases.
|
|
* So, don't be too eager to convert old code.
|
|
*
|
|
* It uses names not prefixed with Py_.
|
|
* It is also *not* included from Python.h and must be included individually.
