Lz_CompressionName()

const char* Lz_CompressionName

(

CompressionType

type

)

Returns a human-readable name string for a CompressionType enum.

Parameters

type	The compression type.

Returns

Read-only string description of compression algorithm.

Lz_Decompress()

int Lz_Decompress	(	const u8 *	in_data,
		size_t	in_size,
		u8 **	out_data,
		size_t *	out_size,
		CompressionType *	out_type
	)

Decompresses an LZ10 or LZ11 compressed data stream.

Parameters

in_data	Pointer to the raw compressed source buffer.
in_size	Size of the compressed data stream in bytes.
out_data	Pointer to the destination buffer pointer, allocated inside this function.
out_size	Pointer to store the size of the decompressed output buffer.
out_type	Optional output pointer to store the detected compression format.

Returns

0 on success; negative value on invalid headers or decompression buffer overflow.
