Now that we are no longer developing new py2/py3 compatible code we can remove any aspects of this header we do not use. This will make the eventual removal easier. Signed-off-by: Andrew Bartlett <abartlet@samba.org>

/* Quick docs:
|
|
*
|
|
* "PyStr_*" works like PyUnicode_* on Python 3, but uses bytestrings (str)
|
|
* under Python 2.
|
|
*
|
|
* "PyBytes_*" work like in Python 3; on Python 2 they are aliased to their
|
|
* PyString_* names.
|
|
*
|
|
* "PyInt_*" works like PyLong_*
|
|
*
|
|
* Syntax for module initialization is as in Python 3, except the entrypoint
|
|
* function definition and declaration:
|
|
* PyMODINIT_FUNC PyInit_modulename(void);
|
|
* PyMODINIT_FUNC PyInit_modulename(void)
|
|
* {
|
|
* ...
|
|
* }
|
|
* is replaced by:
|
|
* MODULE_INIT_FUNC(modulename)
|
|
* {
|
|
* ...
|
|
* }
|
|
*
|
|
* In the entrypoint, create a module using PyModule_Create and PyModuleDef,
|
|
* and return it. See Python 3 documentation for details.
|
|
* For Python 2 compatibility, always set PyModuleDef.m_size to -1.
