=======================
+.. c:function:: void Py_SetProgramName(const wchar_t *name)
+
+ .. index::
+ single: Py_Initialize()
+ single: main()
+ single: Py_GetPath()
+
+ This API is kept for backward compatibility: setting
+ :c:member:`PyConfig.program_name` should be used instead, see :ref:`Python
+ Initialization Configuration <init-config>`.
+
+ This function should be called before :c:func:`Py_Initialize` is called for
+ the first time, if it is called at all. It tells the interpreter the value
+ of the ``argv[0]`` argument to the :c:func:`main` function of the program
+ (converted to wide characters).
+ This is used by :c:func:`Py_GetPath` and some other functions below to find
+ the Python run-time libraries relative to the interpreter executable. The
+ default value is ``'python'``. The argument should point to a
+ zero-terminated wide character string in static storage whose contents will not
+ change for the duration of the program's execution. No code in the Python
+ interpreter will change the contents of this storage.
+
+ Use :c:func:`Py_DecodeLocale` to decode a bytes string to get a
+ :c:expr:`wchar_*` string.
+
+ .. deprecated:: 3.11
+
+
.. c:function:: wchar_t* Py_GetProgramName()
Return the program name set with :c:member:`PyConfig.program_name`, or the default.
``sys.version``.
+.. c:function:: void PySys_SetArgvEx(int argc, wchar_t **argv, int updatepath)
+
+ .. index::
+ single: main()
+ single: Py_FatalError()
+ single: argv (in module sys)
+
+ This API is kept for backward compatibility: setting
+ :c:member:`PyConfig.argv`, :c:member:`PyConfig.parse_argv` and
+ :c:member:`PyConfig.safe_path` should be used instead, see :ref:`Python
+ Initialization Configuration <init-config>`.
+
+ Set :data:`sys.argv` based on *argc* and *argv*. These parameters are
+ similar to those passed to the program's :c:func:`main` function with the
+ difference that the first entry should refer to the script file to be
+ executed rather than the executable hosting the Python interpreter. If there
+ isn't a script that will be run, the first entry in *argv* can be an empty
+ string. If this function fails to initialize :data:`sys.argv`, a fatal
+ condition is signalled using :c:func:`Py_FatalError`.
+
+ If *updatepath* is zero, this is all the function does. If *updatepath*
+ is non-zero, the function also modifies :data:`sys.path` according to the
+ following algorithm:
+
+ - If the name of an existing script is passed in ``argv[0]``, the absolute
+ path of the directory where the script is located is prepended to
+ :data:`sys.path`.
+ - Otherwise (that is, if *argc* is ``0`` or ``argv[0]`` doesn't point
+ to an existing file name), an empty string is prepended to
+ :data:`sys.path`, which is the same as prepending the current working
+ directory (``"."``).
+
+ Use :c:func:`Py_DecodeLocale` to decode a bytes string to get a
+ :c:expr:`wchar_*` string.
+
+ See also :c:member:`PyConfig.orig_argv` and :c:member:`PyConfig.argv`
+ members of the :ref:`Python Initialization Configuration <init-config>`.
+
+ .. note::
+ It is recommended that applications embedding the Python interpreter
+ for purposes other than executing a single script pass ``0`` as *updatepath*,
+ and update :data:`sys.path` themselves if desired.
+ See `CVE-2008-5983 <https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_.
+
+ On versions before 3.1.3, you can achieve the same effect by manually
+ popping the first :data:`sys.path` element after having called
+ :c:func:`PySys_SetArgv`, for example using::
+
+ PyRun_SimpleString("import sys; sys.path.pop(0)\n");
+
+ .. versionadded:: 3.1.3
+
+ .. XXX impl. doesn't seem consistent in allowing ``0``/``NULL`` for the params;
+ check w/ Guido.
+
+ .. deprecated:: 3.11
+
+
+.. c:function:: void PySys_SetArgv(int argc, wchar_t **argv)
+
+ This API is kept for backward compatibility: setting
+ :c:member:`PyConfig.argv` and :c:member:`PyConfig.parse_argv` should be used
+ instead, see :ref:`Python Initialization Configuration <init-config>`.
+
+ This function works like :c:func:`PySys_SetArgvEx` with *updatepath* set
+ to ``1`` unless the :program:`python` interpreter was started with the
+ :option:`-I`.
+
+ Use :c:func:`Py_DecodeLocale` to decode a bytes string to get a
+ :c:expr:`wchar_*` string.
+
+ See also :c:member:`PyConfig.orig_argv` and :c:member:`PyConfig.argv`
+ members of the :ref:`Python Initialization Configuration <init-config>`.
+
+ .. versionchanged:: 3.4 The *updatepath* value depends on :option:`-I`.
+
+ .. deprecated:: 3.11
+
+
+.. c:function:: void Py_SetPythonHome(const wchar_t *home)
+
+ This API is kept for backward compatibility: setting
+ :c:member:`PyConfig.home` should be used instead, see :ref:`Python
+ Initialization Configuration <init-config>`.
+
+ Set the default "home" directory, that is, the location of the standard
+ Python libraries. See :envvar:`PYTHONHOME` for the meaning of the
+ argument string.
+
+ The argument should point to a zero-terminated character string in static
+ storage whose contents will not change for the duration of the program's
+ execution. No code in the Python interpreter will change the contents of
+ this storage.
+
+ Use :c:func:`Py_DecodeLocale` to decode a bytes string to get a
+ :c:expr:`wchar_*` string.
+
+ .. deprecated:: 3.11
+
+
.. c:function:: wchar_t* Py_GetPythonHome()
