Changes the mode of the directory.
The process must have the correct privileges in order to do this
successfully, or must have the effective user ID matching the owner
of the directory. Additionally, the directory must have been opened
with OpenOptions{ .iterate = true }.

Functions in this namespace
Functions
- iterateAssumeFirstIteration
- Like `iterate`, but will not reset the directory cursor before the first
- walk
- Recursively iterates over a directory.
- openFile
- Opens a file for reading or writing, without attempting to create a new file.
- openFileZ
- Same as `openFile` but the path parameter is null-terminated.
- openFileW
- Same as `openFile` but Windows-only and the path parameter is
- createFile
- Creates, opens, or overwrites a file with write access.
- createFileZ
- Same as `createFile` but the path parameter is null-terminated.
- createFileW
- Same as `createFile` but Windows-only and the path parameter is
- makeDir
- Creates a single directory with a relative or absolute path.
- makeDirZ
- Same as `makeDir`, but `sub_path` is null-terminated.
- makeDirW
- Creates a single directory with a relative or absolute null-terminated WTF-16 LE-encoded path.
- makePath
- Calls makeDir iteratively to make an entire path
- makePathStatus
- Same as `makePath` except returns whether the path already existed or was successfully created.
- makeOpenPath
- This function performs `makePath`, followed by `openDir`.
- realpath
- This function returns the canonicalized absolute pathname of
- realpathZ
- Same as `Dir.realpath` except `pathname` is null-terminated.
- realpathW
- Windows-only.
- realpathAlloc
- Same as `Dir.realpath` except caller must free the returned memory.
- setAsCwd
- Changes the current working directory to the open directory handle.
- openDir
- Opens a directory at the given path.
- openDirZ
- Same as `openDir` except the parameter is null-terminated.
- openDirW
- Same as `openDir` except the path parameter is WTF-16 LE encoded, NT-prefixed.
- deleteFile
- Delete a file name and possibly the file it refers to, based on an open directory handle.
- deleteFileZ
- Same as `deleteFile` except the parameter is null-terminated.
- deleteFileW
- Same as `deleteFile` except the parameter is WTF-16 LE encoded.
- deleteDir
- Returns `error.DirNotEmpty` if the directory is not empty.
- deleteDirZ
- Same as `deleteDir` except the parameter is null-terminated.
- deleteDirW
- Same as `deleteDir` except the parameter is WTF16LE, NT prefixed.
- rename
- Change the name or location of a file or directory.
- renameZ
- Same as `rename` except the parameters are null-terminated.
- renameW
- Same as `rename` except the parameters are WTF16LE, NT prefixed.
- symLink
- Creates a symbolic link named `sym_link_path` which contains the string `target_path`.
- symLinkWasi
- WASI-only.
- symLinkZ
- Same as `symLink`, except the pathname parameters are null-terminated.
- symLinkW
- Windows-only.
- atomicSymLink
- Same as `symLink`, except tries to create the symbolic link until it
- readLink
- Read value of a symbolic link.
- readLinkWasi
- WASI-only.
- readLinkZ
- Same as `readLink`, except the `sub_path_c` parameter is null-terminated.
- readLinkW
- Windows-only.
- readFile
- Read all of file contents using a preallocated buffer.
- readFileAlloc
- On success, caller owns returned buffer.
- readFileAllocOptions
- On success, caller owns returned buffer.
- deleteTree
- Whether `sub_path` describes a symlink, file, or directory, this function
- deleteTreeMinStackSize
- Like `deleteTree`, but only keeps one `Iterator` active at a time to minimize the function's stack size.
- writeFile
- Writes content to the file system, using the file creation flags provided.
- access
- Test accessing `sub_path`.
- accessZ
- Same as `access` except the path parameter is null-terminated.

- Check the file size, mtime, and mode of `source_path` and `dest_path`.
- copyFile
- Atomically creates a new file at `dest_path` within `dest_dir` with the
- atomicFile
- Directly access the `.file` field, and then call `AtomicFile.finish` to
- statFile
- Returns metadata for a file inside the directory.
- chmod
- Changes the mode of the directory.
- chown
- Changes the owner and group of the directory.
- setPermissions
- Sets permissions according to the provided `Permissions` struct.
