+/// `close(raw_fd)`—Closes a `RawFd` directly.
+///
+/// Most users won't need to use this, as [`OwnedFd`] automatically closes its
+/// file descriptor on `Drop`.
+///
+/// This function does not return a `Result`, as it is the [responsibility] of
+/// filesystem designers to not return errors from `close`. Users who chose to
+/// use NFS or similar filesystems should take care to monitor for problems
+/// externally.
