"Overview\n"
"\n"
"Easylzma is a C library and command line tools for LZMA compression and \n"
"decompression. It uses a Igor Pavlov's reference implementation and SDK\n"
"written in C.\n"
"\n"
"License\n"
"\n"
"All the cruft you find here is public domain. You don't have to credit\n"
"anyone to use this code, but my personal request is that you mention\n"
"Igor Pavlov for his hard, high quality work.\n"
"\n"
"Project Goals\n"
"\n"
"1. A tiny C wrapper and portable build system around a subset of\n"
" Igor Pavlov's public domain LZMA compression and decompression\n"
" implementation.\n"
"2. A tiny and straighforward API\n"
"3. Support for multiple different prominent LZMA file formats (see section on\n"
" file formats below)\n"
"4. easy to build and use everywhere (doze and nix alike)\n"
"5. public domain licensing through and through. (hats off to Igor)\n"
"\n"
"Current State:\n"
"\n"
"THIS IS A WORK IN PROGRESS. The code here should be considered pre-alpha,\n"
"and this should only be used by tinkerers or hackers at this point. Once\n"
"feature completion is attained this message will be updated. See the\n"
"TODO file distributed with the source for remaining work to be done.\n"
"\n"
"Platforms Supported\n"
"\n"
"0.0.2 has been successfully compiled and run basic round trip testing\n"
"on the following platforms & compilers:\n"
"\n"
" * win32 - visual studio 2005\n"
" * osx - 10.4 & 10.5 (intel)\n"
" * netbsd ppc - 4.0.1 with gcc 4.1.2\n"
" (NOTE: memory allocation errors when dict size is default)\n"
" * freebsd 6.1 - amd64 gcc 3.4.4\n"

"\n"
"XXX: write me (and the code)\n"
"\n"
"The Saga of LZMA File Formats, and a couple cents.\n"
"\n"
"As far as I can tell, there are at least four different ways to put LZMA\n"
"compressed data in a stream:\n"
"\n"
"1. The LZMA-Alone format, which consists of a 13 byte header including\n"
" compression properties, dictionary size, and the uncompressed size of\n"
" the file, followed by compressed data. This format has some support\n"
" in Igor Pavlov's reference implementation and is in widespread use, as\n"
" it's supported by lzmautils: http://tukaani.org/lzma/\n"
"\n"
" The canonical (afaict) implementation of this format (lzmautis) is\n"
" BSD licensed.\n"
"\n"
"2. The lzip format (http://www.nongnu.org/lzip/lzip.html) - which\n"
" includes a CRC footer and leading \"magic number\". The former\n"
" affords data integrity gaurantees, while the latter simplifies\n"
" heuristic determination of file format. This format looks to have\n"
" reasonably widespread usage, though not quite as significant as\n"
" LZMA-Alone.\n"
"\n"
" The only implementation of this format I can find (lzip) is GPL licensed.\n"
"\n"
"3. the xz format ( http://tukaani.org/xz/xz-file-format.txt ) which is\n"
" a more complex representation that includes CRC support and a magic\n"
" number. This format is to be supported by the next iteration of\n"
" XZ Utils which is currently in beta. The source may be obtained\n"
" here: git://ctrl.tukaani.org/xz.git\n"
"\n"
" This format will address some criticisms to the LZMA-Alone format and\n"
" was developed collaboratively by Lasse Collin (the current maintainer\n"
" of XZ utils) and Igor Pavlov (the author of 7zip and the refrence\n"
" implementation of LZMA).\n"
"\n"
" The xz format will employ LZMA2 which consists of extensions on top\n"
" of LZMA, in the xz utils maintainer's words:\n"
"\n"
" \"The primary compression algorithm in .xz is currently LZMA2, which\n"
" is an extension on top of the orignal LZMA to fix a few practical\n"
" issues, like adding support for flushing the encoder (equivalent\n"
" to zlib's Z_SYNC_FLUSH), which isn't possible with the original\n"
" LZMA.\"\n"
"\n"
" Again, maintainers words, regarding licensing:\n"
"\n"
" \"XZ Utils currently contains a zlib-like compression library and a \n"
" gzip-like command line tool. It's currently under LGPLv2.1+ but I will \n"
" put it into the public domain before the first stable release.\"\n"
"\n"
"4. The 7zip disk format which can contain multiple files possibly stored in\n"
" LZMA compressed format.\n"
"\n"
"Given the state of things, the goal of this project is to develop something\n"
"based on the existing formats, and quickly leverage code generated by the XZ\n"
"Utils project, or simply kill this thing if that project produces something\n"
"that's easy to embed and has a clean API at a similar level of abstraction\n"
"as easylzma.\n"
"\n"

In: the pointer to the size of outProps buffer; *outPropsSize = LZMA_PROPS_SIZE = 5.
Out: the pointer to the size of written properties in outProps buffer; *outPropsSize =
LZMA_PROPS_SIZE = 5.
LZMA Encoder will use defult values for any parameter, if it is
-1 for any from: level, loc, lp, pb, fb, numThreads
0 for dictSize
level - compression level: 0 <= level <= 9;
level dictSize algo fb
0: 16 KB 0 32
1: 64 KB 0 32
2: 256 KB 0 32
3: 1 MB 0 32
4: 4 MB 0 32
5: 16 MB 1 32
6: 32 MB 1 32
7+: 64 MB 1 64
The default value for "level" is 5.
algo = 0 means fast method
algo = 1 means normal method
dictSize - The dictionary size in bytes. The maximum value is
128 MB = (1 << 27) bytes for 32-bit version
1 GB = (1 << 30) bytes for 64-bit version
The default value is 16 MB = (1 << 24) bytes.
It's recommended to use the dictionary that is larger than 4 KB and
that can be calculated as (1 << N) or (3 << N) sizes.
lc - The number of literal context bits (high bits of previous literal).
It can be in the range from 0 to 8. The default value is 3.
Sometimes lc=4 gives the gain for big files.
lp - The number of literal pos bits (low bits of current position for literals).
It can be in the range from 0 to 4. The default value is 0.
The lp switch is intended for periodical data when the period is equal to 2^lp.
For example, for 32-bit (4 bytes) periodical data you can use lp=2. Often it's
better to set lc=0, if you change lp switch.
pb - The number of pos bits (low bits of current position).
It can be in the range from 0 to 4. The default value is 2.
The pb switch is intended for periodical data when the period is equal 2^pb.
fb - Word size (the number of fast bytes).
It can be in the range from 5 to 273. The default value is 32.
Usually, a big number gives a little bit better compression ratio and
slower compression process.
numThreads - The number of thereads. 1 or 2. The default value is 2.
Fast mode (algo = 0) can use only 1 thread.
Out:
destLen - processed output size
Returns:
SZ_OK - OK
SZ_ERROR_MEM - Memory allocation error
SZ_ERROR_PARAM - Incorrect paramater
SZ_ERROR_OUTPUT_EOF - output buffer overflow
SZ_ERROR_THREAD - errors in multithreading functions (only for Mt version)
