30.10.15.32 Rename [fs.op.rename]

void rename(const path& old_p, const path& new_p); void rename(const path& old_p, const path& new_p, error_code& ec) noexcept;

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

[Note:

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

  • Otherwise, the rename may include the following effects:

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

    • 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]

Throws: As specified in [fs.err.report].
