	msg	Description of the last error (null if no errors).
	next_in	Input buffer.
	next_in_index	Position of cursor into input buffer.
	next_out	Output buffer.
	next_out_index	Position of cursor into the output buffer.
	total_in	Total number of input bytes read so far.
	total_out	Total number of bytes output so far.
	Z_BUF_ERROR	No progress possible or no room in output buffer.
	Z_DATA_ERROR	Input data is corrupted (wrong format or checksum).
	Z_ERRNO	File error.
	Z_MEM_ERROR	Not enough memory.
	Z_NEED_DICT	A preset dictionary is needed at this point.
	Z_OK	No error.

Public Methods

	Name	Description
	deflate	Compresses as much data as possible, and stops when the input buffer becomes empty or the output buffer becomes full.
	deflateEnd	Frees all dynamically allocated data structures for this stream, discards any unprocessed input, and does not flush any pending output.
	deflateInit	Overloaded. Initializes the internal stream state for compression.
	deflateParams	Dynamically updates the compression level and compression strategy.
	deflateSetDictionary	Initializes the compression dictionary from the given byte sequence without producing any compressed output.
	inflate	Decompresses as much data as possible until the input buffer is exhausted or the output buffer is full.
	inflateEnd	Frees all dynamically allocated data structures for this stream, discards any unprocessed input, and does not flush any pending output.
	inflateInit	Overloaded. Initializes the internal stream state for decompression.
	inflateSetDictionary	Initializes the decompression dictionary from the given uncompressed byte sequence.
	inflateSync	Skips invalid compressed data until a full flush point is found, or until all available input is skipped. No output is provided.
