of the compiler used. Different compilers define their own feature

* A number of APIs are available on macOS from a certain macOS version.
* To support building with a new SDK while deploying to older versions
* the availability test is split into two:
* - HAVE_<FUNCTION>: The configure check for compile time availability
* - HAVE_<FUNCTION>_RUNTIME: Runtime check for availability
*
* The latter is always true when not on macOS, or when using a compiler
* that does not support __has_builtin (older versions of Xcode).
*
* Due to compiler restrictions there is one valid use of HAVE_<FUNCTION>_RUNTIME:
* if (HAVE_<FUNCTION>_RUNTIME) { ... }

/*
* A PyArg_ParseTuple "converter" function
* that handles filesystem paths in the manner
* preferred by the os module.
*
* path_converter accepts (Unicode) strings and their
* subclasses, and bytes and their subclasses. What
* it does with the argument depends on path.make_wide:
*
* * If path.make_wide is nonzero, if we get a (Unicode)
* string we extract the wchar_t * and return it; if we
* get bytes we decode to wchar_t * and return that.
*
* * If path.make_wide is zero, if we get bytes we extract
* the char_t * and return it; if we get a (Unicode)
* string we encode to char_t * and return that.
*
* path_converter also optionally accepts signed
* integers (representing open file descriptors) instead
* of path strings.
*
* Input fields:
* path.nullable
* If nonzero, the path is permitted to be None.
* path.nonstrict
* If nonzero, the path is permitted to contain
* embedded null characters and have any length.
* path.make_wide
* If nonzero, the converter always uses wide, decoding if necessary, else
* it always uses narrow, encoding if necessary. The default value is
* nonzero on Windows, else zero.
* path.suppress_value_error
* If nonzero, raising ValueError is suppressed.
* path.allow_fd
* If nonzero, the path is permitted to be a file handle
* (a signed int) instead of a string.
* path.function_name
* If non-NULL, path_converter will use that as the name
* of the function in error messages.
* (If path.function_name is NULL it omits the function name.)
* path.argument_name
* If non-NULL, path_converter will use that as the name
* of the parameter in error messages.
* (If path.argument_name is NULL it uses "path".)
*
* Output fields:
* path.wide
* Points to the path if it was expressed as Unicode
* or if it was bytes and decoded to Unicode.
* path.narrow
* Points to the path if it was expressed as bytes,
* or if it was Unicode and encoded to bytes.
* path.fd
* Contains a file descriptor if path.accept_fd was true
* and the caller provided a signed integer instead of any
* sort of string.
*
* WARNING: if your "path" parameter is optional, and is
* unspecified, path_converter will never get called.
* So if you set allow_fd, you *MUST* initialize path.fd = -1
* yourself!
* path.value_error
* If nonzero, then suppress_value_error was specified and a ValueError
* occurred.
* path.length
* The length of the path in characters, if specified as
* a string.
* path.object
* The original object passed in (if get a PathLike object,
* the result of PyOS_FSPath() is treated as the original object).
* Own a reference to the object.
* path.cleanup
* For internal use only. May point to a temporary object.
* (Pay no attention to the man behind the curtain.)
*
* At most one of path.wide or path.narrow will be non-NULL.
* If path was None and path.nullable was set,
* or if path was an integer and path.allow_fd was set,
* both path.wide and path.narrow will be NULL
* and path.length will be 0.
*
* path_converter takes care to not write to the path_t
* unless it's successful. However it must reset the
* "cleanup" field each time it's called.
*
* Use as follows:
* path_t path;
* memset(&path, 0, sizeof(path));
* PyArg_ParseTuple(args, "O&", path_converter, &path);
* // ... use values from path ...
* path_cleanup(&path);
*
* (Note that if PyArg_Parse fails you don't need to call
* path_cleanup(). However it is safe to do so.)

Set the access and modified time of path.
path may always be specified as a string.
On some platforms, path may also be specified as an open file descriptor.
If this functionality is unavailable, using it raises an exception.
If times is not None, it must be a tuple (atime, mtime);
atime and mtime should be expressed as float seconds since the epoch.
If ns is specified, it must be a tuple (atime_ns, mtime_ns);
atime_ns and mtime_ns should be expressed as integer nanoseconds
since the epoch.
If times is None and ns is unspecified, utime uses the current time.
Specifying tuples for both times and ns is an error.
If dir_fd is not None, it should be a file descriptor open to a directory,
and path should be relative; path will then be relative to that directory.
If follow_symlinks is False, and the last element of the path is a symbolic
link, utime will modify the symbolic link itself instead of the file the
link points to.
It is an error to use dir_fd or follow_symlinks when specifying path
as an open file descriptor.
dir_fd and follow_symlinks may not be available on your platform.
If they are unavailable, using them will raise a NotImplementedError.

os.startfile
filepath: path_t
operation: Py_UNICODE = NULL
arguments: Py_UNICODE = NULL

Start a file with its associated application.
When "operation" is not specified or "open", this acts like
double-clicking the file in Explorer, or giving the file name as an
argument to the DOS "start" command: the file is opened with whatever
application (if any) its extension is associated.
When another "operation" is given, it specifies what should be done with
the file. A typical operation is "print".
"arguments" is passed to the application, but should be omitted if the
file is a document.
"cwd" is the working directory for the operation. If "filepath" is
relative, it will be resolved against this directory. This argument
should usually be an absolute path.
"show_cmd" can be used to override the recommended visibility option.
See the Windows ShellExecute documentation for values.
startfile returns as soon as the associated application is launched.
There is no option to wait for the application to close, and no way
to retrieve the application's exit status.
The filepath is relative to the current directory. If you want to use
an absolute path, make sure the first character is not a slash ("/");
