Function Documentation

lzma_ret lzma_auto_decoder	(	lzma_stream *	strm,
		uint64_t	memlimit,
		uint32_t	flags
	)

Decode .xz Streams and .lzma files with autodetection.

This decoder autodetects between the .xz and .lzma file formats, and calls lzma_stream_decoder() or lzma_alone_decoder() once the type of the input file has been detected.

Parameters:

	strm	Pointer to properly prepared lzma_stream
	memlimit	Memory usage limit as bytes. Use UINT64_MAX to effectively disable the limiter.
	flags	Bitwise-or of flags, or zero for no flags.

Returns:

- LZMA_OK: Initialization was successful.

• LZMA_MEM_ERROR: Cannot allocate memory.
• LZMA_OPTIONS_ERROR: Unsupported flags
• LZMA_PROG_ERROR
