26 * "PyStr_*" works like PyUnicode_* on Python 3, but uses bytestrings (str)
29 * "PyBytes_*" work like in Python 3; on Python 2 they are aliased to their
32 * "PyInt_*" works like PyLong_*
34 * Syntax for module initialization is as in Python 3, except the entrypoint
35 * function definition and declaration:
36 * PyMODINIT_FUNC PyInit_modulename(void);
37 * PyMODINIT_FUNC PyInit_modulename(void)
42 * MODULE_INIT_FUNC(modulename)
47 * In the entrypoint, create a module using PyModule_Create and PyModuleDef,
48 * and return it. See Python 3 documentation for details.
49 * For Python 2 compatibility, always set PyModuleDef.m_size to -1.
