+      Renames the underlying shared memory block to ``newname``. By
+      default, if ``newname`` already exists, it will be unlinked
+      beforehand. Passing the ``os.SHM_RENAME_EXCHANGE`` as ``flags``,
+      an exchange with ``newname``  will be proceeded instead. Passing
+      the ``os.SHM_RENAME_NOREPLACE`` as ``flags``, an error
+      will be triggered if ``newname`` already exists.
