// Directory tree generator.
//
//	For each directory in the directory tree rooted at top (including top
//	itself, but excluding '.' and '..'), yields a 3-tuple
//
//	    dirpath, dirnames, filenames
//
//	dirpath is a string, the path to the directory.  dirnames is a list of
//	the names of the subdirectories in dirpath (including symlinks to directories,
//	and excluding '.' and '..').
//	filenames is a list of the names of the non-directory files in dirpath.
//	Note that the names in the lists are just names, with no path components.
//	To get a full path (which begins with top) to a file or directory in
//	dirpath, do os.path.join(dirpath, name).
//
//	If optional arg 'topdown' is true or not specified, the triple for a
//	directory is generated before the triples for any of its subdirectories
//	(directories are generated top down).  If topdown is false, the triple
//	for a directory is generated after the triples for all of its
//	subdirectories (directories are generated bottom up).
//
//	When topdown is true, the caller can modify the dirnames list in-place
//	(e.g., via del or slice assignment), and walk will only recurse into the
//	subdirectories whose names remain in dirnames; this can be used to prune the
//	search, or to impose a specific order of visiting.  Modifying dirnames when
//	topdown is false has no effect on the behavior of os.walk(), since the
//	directories in dirnames have already been generated by the time dirnames
//	itself is generated. No matter the value of topdown, the list of
//	subdirectories is retrieved before the tuples for the directory and its
//	subdirectories are generated.
//
//	By default errors from the os.scandir() call are ignored.  If
//	optional arg 'onerror' is specified, it should be a function; it
//	will be called with one argument, an OSError instance.  It can
//	report the error to continue with the walk, or raise the exception
//	to abort the walk.  Note that the filename is available as the
//	filename attribute of the exception object.
//
//	By default, os.walk does not follow symbolic links to subdirectories on
//	systems that support them.  In order to get this functionality, set the
//	optional argument 'followlinks' to true.
//
//	Caution:  if you pass a relative pathname for top, don't change the
//	current working directory between resumptions of walk.  walk never
//	changes the current directory, and assumes that the client doesn't
//	either.
//
//	Example:
//
//	import os
//	from os.path import join, getsize
//	for root, dirs, files in os.walk('python/Lib/email'):
//	    print(root, "consumes ")
//	    print(sum(getsize(join(root, name)) for name in files), end=" ")
//	    print("bytes in", len(files), "non-directory files")
//	    if 'CVS' in dirs:
//	        dirs.remove('CVS')  # don't visit CVS directories

// Directory tree generator.
//
//	This behaves exactly like walk(), except that it yields a 4-tuple
//
//	    dirpath, dirnames, filenames, dirfd
//
//	`dirpath`, `dirnames` and `filenames` are identical to walk() output,
//	and `dirfd` is a file descriptor referring to the directory `dirpath`.
//
//	The advantage of fwalk() over walk() is that it's safe against symlink
//	races (when follow_symlinks is False).
//
//	If dir_fd is not None, it should be a file descriptor open to a directory,
//	  and top should be relative; top will then be relative to that directory.
//	  (dir_fd is always supported for fwalk.)
//
//	Caution:
//	Since fwalk() yields file descriptors, those are only valid until the
//	next iteration step, so you should dup() them if you want to keep them
//	for a longer period.
//
//	Example:
//
//	import os
//	for root, dirs, files, rootfd in os.fwalk('python/Lib/email'):
