Functions
int	bsl_mock_decode_eid (const BSL_Data_t *encoded_bytes, BSL_HostEID_t *eid)
	Decode a single EID.
int	bsl_mock_decode_eid_from_ctx (QCBORDecodeContext *dec, BSL_HostEID_t *eid)
	Decode a single EID from a QCBOR Decode Context.
int	bsl_mock_decode_primary (QCBORDecodeContext *dec, MockBPA_PrimaryBlock_t *blk)
	Encode primary block to a CBOR bytestring.
int	bsl_mock_decode_canonical (QCBORDecodeContext *dec, MockBPA_CanonicalBlock_t *blk)
	This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
int	bsl_mock_decode_bundle (QCBORDecodeContext *dec, MockBPA_Bundle_t *bundle)
	This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

bsl_mock_decode_eid()

int bsl_mock_decode_eid	(	const BSL_Data_t *	encoded_bytes,
		BSL_HostEID_t *	eid
	)

Decode a single EID.

Matches the signature for the BSL_HostDescriptors_t::eid_from_cbor function.

Parameters

[in]	dec	The encoded bytes to be decoded.
[in,out]	eid	The EID value. The struct must already be initialized.

bsl_mock_decode_eid_from_ctx()

int bsl_mock_decode_eid_from_ctx	(	QCBORDecodeContext *	dec,
		BSL_HostEID_t *	eid
	)

Decode a single EID from a QCBOR Decode Context.

Parameters

[in]	dec	QCBOR Decode Context.
[in,out]	eid	The EID Value.

bsl_mock_decode_primary()

int bsl_mock_decode_primary	(	QCBORDecodeContext *	dec,
		MockBPA_PrimaryBlock_t *	blk
	)

Encode primary block to a CBOR bytestring.

Parameters

[in]	dec	The decoder.
[in,out]	blk	The primary block structure to decode into. The struct must already be initialized.

Returns

0 if successful
