Detailed Description

Decoder for LZMA_Alone files.

Function Documentation

lzma_alone_decoder()

lzma_ret lzma_alone_decoder	(	lzma_stream *	strm,
		uint64_t	memlimit
	)

Initialize .lzma decoder (legacy file format)

Parameters

strm	Pointer to properly prepared lzma_stream
memlimit	Memory usage limit as bytes. Use UINT64_MAX to effectively disable the limiter. liblzma 5.2.3 and earlier don't allow 0 here and return LZMA_PROG_ERROR; later versions treat 0 as if 1 had been specified.

Valid `action' arguments to lzma_code() are LZMA_RUN and LZMA_FINISH. There is no need to use LZMA_FINISH, but it's allowed because it may simplify certain types of applications.

Returns

- LZMA_OK

• LZMA_MEM_ERROR
• LZMA_PROG_ERROR
