[−][src]Function nix::unistd::fchownat
pub fn fchownat<P: ?Sized + NixPath>(
dirfd: Option<RawFd>,
path: &P,
owner: Option<Uid>,
group: Option<Gid>,
flag: FchownatFlags
) -> Result<()>
Change the ownership of the file at path to be owned by the specified
owner (user) and group.
The owner/group for the provided path name will not be modified if None is
provided for that argument. Ownership change will be attempted for the path
only if Some owner/group is provided.
The file to be changed is determined relative to the directory associated
with the file descriptor dirfd or the current working directory
if dirfd is None.
If flag is FchownatFlags::NoFollowSymlink and path names a symbolic link,
then the mode of the symbolic link is changed.
fchownat(None, path, mode, FchownatFlags::NoFollowSymlink) is identical to
a call libc::lchown(path, mode). That's why lchmod is unimplemented in
the nix crate.
