41 * \addtogroup CborEncoding
47 * Closes the CBOR container (array or map) provided by \a containerEncoder and
48 * updates the CBOR stream provided by \a encoder. Both parameters must be the
49 * same as were passed to cbor_encoder_create_array() or
50 * cbor_encoder_create_map().
52 * Unlike cbor_encoder_close_container(), this function checks that the number
53 * of items (or pair of items, in the case of a map) was correct. If the number
54 * of items inserted does not match the length originally passed to
55 * cbor_encoder_create_array() or cbor_encoder_create_map(), this function
56 * returns either CborErrorTooFewItems or CborErrorTooManyItems.
