Effects: Renames old_­p to new_­p, as if by POSIX rename().

[ Note:

  • (1.1)

    If old_­p and new_­p resolve to the same existing file, no action is taken.

  • (1.2)

    Otherwise, the rename may include the following effects:

    • (1.2.1)

      if new_­p resolves to an existing non-directory file, new_­p is removed; otherwise,

    • (1.2.2)

      if new_­p resolves to an existing directory, new_­p is removed if empty on POSIX compliant operating systems but may be an error on other operating systems.

A symbolic link is itself renamed, rather than the file it resolves to.  — end note ]
