Function mkdirat

pub fn mkdirat<Fd: AsFd, P: ?Sized + NixPath>(
    dirfd: Fd,
    path: &P,
    mode: Mode,
) -> Result<()>

Create a directory at the path specified by dirfd and path.

If path is a relative path, then it is interpreted relative to the directory referred to by the file descriptor dirfd. (One can use AT_FDCWD to specify the current working directory in dirfd). If path is absolute, then dirfd is ignored.
