mock_bpa_crc_apply()

void mock_bpa_crc_apply	(	UsefulBuf	buf,
		size_t	begin,
		size_t	end,
		BSL_BundleCRCType_e	crc_type
	)

Apply a CRC function to an encoded block.

Parameters

buf	The buffer holding the encoded block. The buffer contents will be modified to hold the correct CRC value.
begin	The start of the block array
end	The end of the block array
crc_type	The needed CRC type.

mock_bpa_crc_check()

bool mock_bpa_crc_check	(	UsefulBufC	buf,
		size_t	begin,
		size_t	end,
		BSL_BundleCRCType_e	crc_type
	)

Check the CRC of an encoded block.

Parameters

buf	The buffer holding the encoded block.
begin	The start of the block array
end	The end of the block array
crc_type	The needed CRC type.

Returns

True if the CRC value agrees.
