Function Documentation

◆ ZSTD_buildCTable()

size_t ZSTD_buildCTable	(	void *	dst,
		size_t	dstCapacity,
		FSE_CTable *	nextCTable,
		U32	FSELog,
		symbolEncodingType_e	type,
		unsigned *	count,
		U32	max,
		const BYTE *	codeTable,
		size_t	nbSeq,
		const S16 *	defaultNorm,
		U32	defaultNormLog,
		U32	defaultMax,
		const FSE_CTable *	prevCTable,
		size_t	prevCTableSize,
		void *	entropyWorkspace,
		size_t	entropyWorkspaceSize )

◆ ZSTD_crossEntropyCost()

size_t ZSTD_crossEntropyCost	(	short const *	norm,
		unsigned	accuracyLog,
		unsigned const *	count,
		unsigned const	max )

Returns the cost in bits of encoding the distribution in count using the table described by norm. The max symbol support by norm is assumed >= max. norm must be valid for every symbol with non-zero probability in count.

◆ ZSTD_encodeSequences()

size_t ZSTD_encodeSequences	(	void *	dst,
		size_t	dstCapacity,
		FSE_CTable const *	CTable_MatchLength,
		BYTE const *	mlCodeTable,
		FSE_CTable const *	CTable_OffsetBits,
		BYTE const *	ofCodeTable,
		FSE_CTable const *	CTable_LitLength,
		BYTE const *	llCodeTable,
		seqDef const *	sequences,
		size_t	nbSeq,
		int	longOffsets,
		int	bmi2 )

◆ ZSTD_encodeSequences_body()

FORCE_INLINE_TEMPLATE size_t ZSTD_encodeSequences_body	(	void *	dst,
		size_t	dstCapacity,
		FSE_CTable const *	CTable_MatchLength,
		BYTE const *	mlCodeTable,
		FSE_CTable const *	CTable_OffsetBits,
		BYTE const *	ofCodeTable,
		FSE_CTable const *	CTable_LitLength,
		BYTE const *	llCodeTable,
		seqDef const *	sequences,
		size_t	nbSeq,
		int	longOffsets )

◆ ZSTD_fseBitCost()

size_t ZSTD_fseBitCost	(	FSE_CTable const *	ctable,
		unsigned const *	count,
		unsigned const	max )

Returns the cost in bits of encoding the distribution in count using ctable. Returns an error if ctable cannot represent all the symbols in count.

◆ ZSTD_selectEncodingType()

symbolEncodingType_e ZSTD_selectEncodingType	(	FSE_repeat *	repeatMode,
		unsigned const *	count,
		unsigned const	max,
		size_t const	mostFrequent,
		size_t	nbSeq,
		unsigned const	FSELog,
		FSE_CTable const *	prevCTable,
		short const *	defaultNorm,
		U32	defaultNormLog,
		ZSTD_defaultPolicy_e const	isDefaultAllowed,
		ZSTD_strategy const	strategy )
