.. code-block:: console

    int fcb_append_finish(struct fcb *fcb, struct fcb_entry *append_loc);

Finalizes the write of new element. FCB computes the checksum over the
element and updates it in flash.

Returned values
^^^^^^^^^^^^^^^

Returns 0 on success; nonzero on failure.

Notes
^^^^^

You need to call fcb\_append\_finish() after writing the element
contents. Otherwise FCB will consider this entry to be invalid, and
skips over it when reading.
