and has no change on the compression ratio. I compress 8M FVMAIN image,
the compression time is reduced from 2.590s to 1.419s.

+HISTORY of the LZMA SDK
+-----------------------
+
+16.04          2016-10-04
+-------------------------
+- The bug was fixed in DllSecur.c.
+
+
+16.03          2016-09-28
+-------------------------
+- SFX modules now use some protection against DLL preloading attack.
+- Some bugs in 7z code were fixed.
+
+
+16.02          2016-05-21
+-------------------------
+- The BUG in 16.00 - 16.01 was fixed:
+  Split Handler (SplitHandler.cpp) returned incorrect 
+  total size value (kpidSize) for split archives.
+
+
+16.01          2016-05-19
+-------------------------	
+- Some internal changes to reduce the number of compiler warnings.
+
+
+16.00          2016-05-10
+-------------------------	
+- Some bugs were fixed.
+
+
+15.12          2015-11-19
+-------------------------	
+- The BUG in C version of 7z decoder was fixed:
+  7zDec.c : SzDecodeLzma2()
+  7z decoder could mistakenly report about decoding error for some 7z archives
+  that use LZMA2 compression method.
+  The probability to get that mistaken decoding error report was about 
+  one error per 16384 solid blocks for solid blocks larger than 16 KB (compressed size). 
+- The BUG (in 9.26-15.11) in C version of 7z decoder was fixed:
+  7zArcIn.c : SzReadHeader2()
+  7z decoder worked incorrectly for 7z archives that contain 
+  empty solid blocks, that can be placed to 7z archive, if some file is 
+  unavailable for reading during archive creation.
+
+
+15.09 beta     2015-10-16
+-------------------------	
+- The BUG in LZMA / LZMA2 encoding code was fixed.
+  The BUG in LzFind.c::MatchFinder_ReadBlock() function.
+  If input data size is larger than (4 GiB - dictionary_size),
+  the following code worked incorrectly:
+  -  LZMA : LzmaEnc_MemEncode(), LzmaEncode() : LZMA encoding functions 
+     for compressing from memory to memory. 
+     That BUG is not related to LZMA encoder version that works via streams.
+  -  LZMA2 : multi-threaded version of LZMA2 encoder worked incorrectly, if 
+     default value of chunk size (CLzma2EncProps::blockSize) is changed 
+     to value larger than (4 GiB - dictionary_size).
+
+
+9.38 beta      2015-01-03
+-------------------------	
+- The BUG in 9.31-9.37 was fixed:
+  IArchiveGetRawProps interface was disabled for 7z archives.
+- The BUG in 9.26-9.36 was fixed:
+  Some code in CPP\7zip\Archive\7z\ worked correctly only under Windows.
+
+
+9.36 beta      2014-12-26
+-------------------------	
+- The BUG in command line version was fixed:
+  7-Zip created temporary archive in current folder during update archive
+  operation, if -w{Path} switch was not specified. 
+  The fixed 7-Zip creates temporary archive in folder that contains updated archive.
+- The BUG in 9.33-9.35 was fixed:
+  7-Zip silently ignored file reading errors during 7z or gz archive creation,
+  and the created archive contained only part of file that was read before error.
+  The fixed 7-Zip stops archive creation and it reports about error.
+
+
+9.35 beta      2014-12-07
+-------------------------	
+- 7zr.exe now support AES encryption.
+- SFX mudules were added to LZMA SDK
+- Some bugs were fixed.
+
+
+9.21 beta      2011-04-11
+-------------------------	
+- New class FString for file names at file systems.
+- Speed optimization in CRC code for big-endian CPUs.
+- The BUG in Lzma2Dec.c was fixed:
+    Lzma2Decode function didn't work.
+
+
+9.18 beta      2010-11-02
+-------------------------	
+- New small SFX module for installers (SfxSetup).
+
+
+9.12 beta      2010-03-24
+-------------------------
+- The BUG in LZMA SDK 9.* was fixed: LZMA2 codec didn't work,
+  if more than 10 threads were used (or more than 20 threads in some modes).
+
+
+9.11 beta      2010-03-15
+-------------------------
+- PPMd compression method support
+   
+
+9.09           2009-12-12
+-------------------------
+- The bug was fixed:
+   Utf16_To_Utf8 funstions in UTFConvert.cpp and 7zMain.c
+   incorrectly converted surrogate characters (the code >= 0x10000) to UTF-8.
+- Some bugs were fixed
+
+
+9.06           2009-08-17
+-------------------------

+    LZMA Encoder in fast compression mode could access memory outside of 
+    allocated range in some rare cases.
+
+
+4.58 beta      2008-05-05
+-------------------------
+- ANSI-C LZMA Decoder was rewritten for speed optimizations.
+- ANSI-C LZMA Encoder was included to LZMA SDK.

+  
+
+4.39 beta      2006-04-14
+-------------------------
+- The bug in versions 4.33b:4.38b was fixed:
+  C++ version of LZMA encoder could not correctly compress 
+  files larger than 2 GB with HC4 match finder (-mfhc4).
+  
+
+4.37 beta      2005-04-06

+LZMA SDK 16.04
+--------------
+
+LZMA SDK provides the documentation, samples, header files,
+libraries, and tools you need to develop applications that 
+use 7z / LZMA / LZMA2 / XZ compression.
+
+LZMA is an improved version of famous LZ77 compression algorithm. 
+It was improved in way of maximum increasing of compression ratio,
+keeping high decompression speed and low memory requirements for 
+decompressing.
+
+LZMA2 is a LZMA based compression method. LZMA2 provides better 
+multithreading support for compression than LZMA and some other improvements.
+
+7z is a file format for data compression and file archiving.
+7z is a main file format for 7-Zip compression program (www.7-zip.org).
+7z format supports different compression methods: LZMA, LZMA2 and others.
+7z also supports AES-256 based encryption.
+
+XZ is a file format for data compression that uses LZMA2 compression.
+XZ format provides additional features: SHA/CRC check, filters for 
+improved compression ratio, splitting to blocks and streams,
+
+

+
+LZMA features
+-------------
+  - Variable dictionary size (up to 1 GB)
+  - Estimated compressing speed: about 2 MB/s on 2 GHz CPU
+  - Estimated decompressing speed: 
+      - 20-30 MB/s on modern 2 GHz cpu
+      - 1-2 MB/s on 200 MHz simple RISC cpu: (ARM, MIPS, PowerPC)
+  - Small memory requirements for decompressing (16 KB + DictionarySize)
+  - Small code size for decompressing: 5-8 KB
+
+LZMA decoder uses only integer operations and can be 
+implemented in any modern 32-bit CPU (or on 16-bit CPU with some conditions).
+
+Some critical operations that affect the speed of LZMA decompression:
+  1) 32*16 bit integer multiply
+  2) Mispredicted branches (penalty mostly depends from pipeline length)
+  3) 32-bit shift and arithmetic operations
+
+The speed of LZMA decompressing mostly depends from CPU speed.
+Memory speed has no big meaning. But if your CPU has small data cache, 
+overall weight of memory speed will slightly increase.
+
+
+How To Use
+----------
+
+Using LZMA encoder/decoder executable
+--------------------------------------
+
+Usage:  LZMA <e|d> inputFile outputFile [<switches>...]
+
+  e: encode file
+
+  d: decode file
+
+  b: Benchmark. There are two tests: compressing and decompressing 
+     with LZMA method. Benchmark shows rating in MIPS (million 
+     instructions per second). Rating value is calculated from 
+     measured speed and it is normalized with Intel's Core 2 results.
+     Also Benchmark checks possible hardware errors (RAM 
+     errors in most cases). Benchmark uses these settings:
+     (-a1, -d21, -fb32, -mfbt4). You can change only -d parameter. 
+     Also you can change the number of iterations. Example for 30 iterations:
+       LZMA b 30
+     Default number of iterations is 10.
+
+<Switches>
+  
+
+  -a{N}:  set compression mode 0 = fast, 1 = normal
+          default: 1 (normal)
+
+  d{N}:   Sets Dictionary size - [0, 30], default: 23 (8MB)
+          The maximum value for dictionary size is 1 GB = 2^30 bytes.
+          Dictionary size is calculated as DictionarySize = 2^N bytes. 
+          For decompressing file compressed by LZMA method with dictionary 
+          size D = 2^N you need about D bytes of memory (RAM).
+
+  -fb{N}: set number of fast bytes - [5, 273], default: 128
+          Usually big number gives a little bit better compression ratio 
+          and slower compression process.
+
+  -lc{N}: set number of literal context bits - [0, 8], default: 3
+          Sometimes lc=4 gives gain for big files.
+
+  -lp{N}: set number of literal pos bits - [0, 4], default: 0
+          lp switch is intended for periodical data when period is 
+          equal 2^N. For example, for 32-bit (4 bytes) 
+          periodical data you can use lp=2. Often it's better to set lc0, 
+          if you change lp switch.
+
+  -pb{N}: set number of pos bits - [0, 4], default: 2
+          pb switch is intended for periodical data 
+          when period is equal 2^N.
+
+  -mf{MF_ID}: set Match Finder. Default: bt4. 
+              Algorithms from hc* group doesn't provide good compression 
+              ratio, but they often works pretty fast in combination with 
+              fast mode (-a0).
+
+              Memory requirements depend from dictionary size 
+              (parameter "d" in table below). 
+
+               MF_ID     Memory                   Description
+
+                bt2    d *  9.5 + 4MB  Binary Tree with 2 bytes hashing.
+                bt3    d * 11.5 + 4MB  Binary Tree with 3 bytes hashing.
+                bt4    d * 11.5 + 4MB  Binary Tree with 4 bytes hashing.
+                hc4    d *  7.5 + 4MB  Hash Chain with 4 bytes hashing.
+
+  -eos:   write End Of Stream marker. By default LZMA doesn't write 
+          eos marker, since LZMA decoder knows uncompressed size 
+          stored in .lzma file header.
+
+  -si:    Read data from stdin (it will write End Of Stream marker).
+  -so:    Write data to stdout
+
+
+Examples:
+
+1) LZMA e file.bin file.lzma -d16 -lc0 
+
+compresses file.bin to file.lzma with 64 KB dictionary (2^16=64K)  
+and 0 literal context bits. -lc0 allows to reduce memory requirements 
+for decompression.
+
+
+2) LZMA e file.bin file.lzma -lc0 -lp2
+
+compresses file.bin to file.lzma with settings suitable 
+for 32-bit periodical data (for example, ARM or MIPS code).
+
+3) LZMA d file.lzma file.bin
+
+decompresses file.lzma to file.bin.
+
+
+Compression ratio hints
+-----------------------
+
+Recommendations
+---------------
+
+To increase the compression ratio for LZMA compressing it's desirable 
+to have aligned data (if it's possible) and also it's desirable to locate
+data in such order, where code is grouped in one place and data is 
+grouped in other place (it's better than such mixing: code, data, code,
+data, ...).
+
+
+Filters
+-------
+You can increase the compression ratio for some data types, using
+special filters before compressing. For example, it's possible to 
+increase the compression ratio on 5-10% for code for those CPU ISAs: 
+x86, IA-64, ARM, ARM-Thumb, PowerPC, SPARC.
+
+You can find C source code of such filters in C/Bra*.* files
+
+You can check the compression ratio gain of these filters with such 
+7-Zip commands (example for ARM code):
+No filter:
+  7z a a1.7z a.bin -m0=lzma
+
+With filter for little-endian ARM code:
+  7z a a2.7z a.bin -m0=arm -m1=lzma        
+
+It works in such manner:
+Compressing    = Filter_encoding + LZMA_encoding
+Decompressing  = LZMA_decoding + Filter_decoding
+
+Compressing and decompressing speed of such filters is very high,
+so it will not increase decompressing time too much.
+Moreover, it reduces decompression time for LZMA_decoding, 
+since compression ratio with filtering is higher.
+
+These filters convert CALL (calling procedure) instructions 
+from relative offsets to absolute addresses, so such data becomes more 
+compressible.
+
+For some ISAs (for example, for MIPS) it's impossible to get gain from such filter.

-LZMA features
--------------
-  - Variable dictionary size (up to 1 GB)
-  - Estimated compressing speed: about 2 MB/s on 2 GHz CPU
-  - Estimated decompressing speed: 
-      - 20-30 MB/s on 2 GHz Core 2 or AMD Athlon 64
-      - 1-2 MB/s on 200 MHz ARM, MIPS, PowerPC or other simple RISC
-  - Small memory requirements for decompressing (16 KB + DictionarySize)
-  - Small code size for decompressing: 5-8 KB
-
-LZMA decoder uses only integer operations and can be 
-implemented in any modern 32-bit CPU (or on 16-bit CPU with some conditions).
-
-Some critical operations that affect the speed of LZMA decompression:
-  1) 32*16 bit integer multiply
-  2) Misspredicted branches (penalty mostly depends from pipeline length)
-  3) 32-bit shift and arithmetic operations
-
-The speed of LZMA decompressing mostly depends from CPU speed.
-Memory speed has no big meaning. But if your CPU has small data cache, 
-overall weight of memory speed will slightly increase.
-
-
-How To Use
-----------
-
-Using LZMA encoder/decoder executable
---------------------------------------
-
-Usage:  LZMA <e|d> inputFile outputFile [<switches>...]
-
-  e: encode file
-
-  d: decode file
-
-  b: Benchmark. There are two tests: compressing and decompressing 
-     with LZMA method. Benchmark shows rating in MIPS (million 
-     instructions per second). Rating value is calculated from 
-     measured speed and it is normalized with Intel's Core 2 results.
-     Also Benchmark checks possible hardware errors (RAM 
-     errors in most cases). Benchmark uses these settings:
-     (-a1, -d21, -fb32, -mfbt4). You can change only -d parameter. 
-     Also you can change the number of iterations. Example for 30 iterations:
-       LZMA b 30
-     Default number of iterations is 10.
-
-<Switches>
-  
-
-  -a{N}:  set compression mode 0 = fast, 1 = normal
-          default: 1 (normal)
-
-  d{N}:   Sets Dictionary size - [0, 30], default: 23 (8MB)
-          The maximum value for dictionary size is 1 GB = 2^30 bytes.
-          Dictionary size is calculated as DictionarySize = 2^N bytes. 
-          For decompressing file compressed by LZMA method with dictionary 
-          size D = 2^N you need about D bytes of memory (RAM).
-
-  -fb{N}: set number of fast bytes - [5, 273], default: 128
-          Usually big number gives a little bit better compression ratio 
-          and slower compression process.
-
-  -lc{N}: set number of literal context bits - [0, 8], default: 3
-          Sometimes lc=4 gives gain for big files.
-
-  -lp{N}: set number of literal pos bits - [0, 4], default: 0
-          lp switch is intended for periodical data when period is 
-          equal 2^N. For example, for 32-bit (4 bytes) 
-          periodical data you can use lp=2. Often it's better to set lc0, 
-          if you change lp switch.
-
-  -pb{N}: set number of pos bits - [0, 4], default: 2
-          pb switch is intended for periodical data 
-          when period is equal 2^N.
-
-  -mf{MF_ID}: set Match Finder. Default: bt4. 
-              Algorithms from hc* group doesn't provide good compression 
-              ratio, but they often works pretty fast in combination with 
-              fast mode (-a0).
-
-              Memory requirements depend from dictionary size 
-              (parameter "d" in table below). 
-
-               MF_ID     Memory                   Description
-
-                bt2    d *  9.5 + 4MB  Binary Tree with 2 bytes hashing.
-                bt3    d * 11.5 + 4MB  Binary Tree with 3 bytes hashing.
-                bt4    d * 11.5 + 4MB  Binary Tree with 4 bytes hashing.
-                hc4    d *  7.5 + 4MB  Hash Chain with 4 bytes hashing.
-
-  -eos:   write End Of Stream marker. By default LZMA doesn't write 
-          eos marker, since LZMA decoder knows uncompressed size 
-          stored in .lzma file header.
-
-  -si:    Read data from stdin (it will write End Of Stream marker).
-  -so:    Write data to stdout
-
-
-Examples:
-
-1) LZMA e file.bin file.lzma -d16 -lc0 
-
-compresses file.bin to file.lzma with 64 KB dictionary (2^16=64K)  
-and 0 literal context bits. -lc0 allows to reduce memory requirements 
-for decompression.
-
-
-2) LZMA e file.bin file.lzma -lc0 -lp2
-
-compresses file.bin to file.lzma with settings suitable 
-for 32-bit periodical data (for example, ARM or MIPS code).
-
-3) LZMA d file.lzma file.bin
-
-decompresses file.lzma to file.bin.
-
-
-Compression ratio hints
------------------------
-
-Recommendations
----------------
-
-To increase the compression ratio for LZMA compressing it's desirable 
-to have aligned data (if it's possible) and also it's desirable to locate
-data in such order, where code is grouped in one place and data is 
-grouped in other place (it's better than such mixing: code, data, code,
-data, ...).
-
-
-Filters
--------
-You can increase the compression ratio for some data types, using
-special filters before compressing. For example, it's possible to 
-increase the compression ratio on 5-10% for code for those CPU ISAs: 
-x86, IA-64, ARM, ARM-Thumb, PowerPC, SPARC.
-
-You can find C source code of such filters in C/Bra*.* files
-
-You can check the compression ratio gain of these filters with such 
-7-Zip commands (example for ARM code):
-No filter:
-  7z a a1.7z a.bin -m0=lzma
-
-With filter for little-endian ARM code:
-  7z a a2.7z a.bin -m0=arm -m1=lzma        
-
-It works in such manner:
-Compressing    = Filter_encoding + LZMA_encoding
-Decompressing  = LZMA_decoding + Filter_decoding
-
-Compressing and decompressing speed of such filters is very high,
-so it will not increase decompressing time too much.
-Moreover, it reduces decompression time for LZMA_decoding, 
-since compression ratio with filtering is higher.
-
-These filters convert CALL (calling procedure) instructions 
-from relative offsets to absolute addresses, so such data becomes more 
-compressible.
-
-For some ISAs (for example, for MIPS) it's impossible to get gain from such filter.
-
-
-LZMA compressed file format

-  5     8   Uncompressed size (little endian). -1 means unknown size
- 13         Compressed data

-
-ANSI-C LZMA Decoder
-~~~~~~~~~~~~~~~~~~~
-
-Please note that interfaces for ANSI-C code were changed in LZMA SDK 4.58.
-If you want to use old interfaces you can download previous version of LZMA SDK
-from sourceforge.net site.
-
-To use ANSI-C LZMA Decoder you need the following files:
-1) LzmaDec.h + LzmaDec.c + Types.h
-LzmaUtil/LzmaUtil.c is example application that uses these files.
-
-
-Memory requirements for LZMA decoding
--------------------------------------
-
-Stack usage of LZMA decoding function for local variables is not 
-larger than 200-400 bytes.
-
-LZMA Decoder uses dictionary buffer and internal state structure.
-Internal state structure consumes
-  state_size = (4 + (1.5 << (lc + lp))) KB
-by default (lc=3, lp=0), state_size = 16 KB.
-
-
-How To decompress data
-----------------------
-
-LZMA Decoder (ANSI-C version) now supports 2 interfaces:
-1) Single-call Decompressing
-2) Multi-call State Decompressing (zlib-like interface)
-
-You must use external allocator:
-Example:
-void *SzAlloc(void *p, size_t size) { p = p; return malloc(size); }
-void SzFree(void *p, void *address) { p = p; free(address); }
-ISzAlloc alloc = { SzAlloc, SzFree };
-
-You can use p = p; operator to disable compiler warnings.
-
-
-Single-call Decompressing
--------------------------
-When to use: RAM->RAM decompressing
-Compile files: LzmaDec.h + LzmaDec.c + Types.h
-Compile defines: no defines
-Memory Requirements:
-  - Input buffer: compressed size
-  - Output buffer: uncompressed size
-  - LZMA Internal Structures: state_size (16 KB for default settings) 
-
-Interface:
-  int LzmaDecode(Byte *dest, SizeT *destLen, const Byte *src, SizeT *srcLen,
-      const Byte *propData, unsigned propSize, ELzmaFinishMode finishMode, 
-      ELzmaStatus *status, ISzAlloc *alloc);
-  In: 
-    dest     - output data
-    destLen  - output data size
-    src      - input data
-    srcLen   - input data size
-    propData - LZMA properties  (5 bytes)
-    propSize - size of propData buffer (5 bytes)
-    finishMode - It has meaning only if the decoding reaches output limit (*destLen).
-	 LZMA_FINISH_ANY - Decode just destLen bytes.
-	 LZMA_FINISH_END - Stream must be finished after (*destLen).
-                           You can use LZMA_FINISH_END, when you know that 
-                           current output buffer covers last bytes of stream. 
-    alloc    - Memory allocator.
-
-  Out: 
-    destLen  - processed output size 
-    srcLen   - processed input size 
-
-  Output:
-    SZ_OK
-      status:
-        LZMA_STATUS_FINISHED_WITH_MARK
-        LZMA_STATUS_NOT_FINISHED 
-        LZMA_STATUS_MAYBE_FINISHED_WITHOUT_MARK
-    SZ_ERROR_DATA - Data error
-    SZ_ERROR_MEM  - Memory allocation error
-    SZ_ERROR_UNSUPPORTED - Unsupported properties
-    SZ_ERROR_INPUT_EOF - It needs more bytes in input buffer (src).
-
-  If LZMA decoder sees end_marker before reaching output limit, it returns OK result,
-  and output value of destLen will be less than output buffer size limit.
-
-  You can use multiple checks to test data integrity after full decompression:
-    1) Check Result and "status" variable.
-    2) Check that output(destLen) = uncompressedSize, if you know real uncompressedSize.
-    3) Check that output(srcLen) = compressedSize, if you know real compressedSize. 
-       You must use correct finish mode in that case. */ 
-
-
-Multi-call State Decompressing (zlib-like interface)
-----------------------------------------------------
-
-When to use: file->file decompressing 
-Compile files: LzmaDec.h + LzmaDec.c + Types.h
-
-Memory Requirements:
- - Buffer for input stream: any size (for example, 16 KB)
- - Buffer for output stream: any size (for example, 16 KB)
- - LZMA Internal Structures: state_size (16 KB for default settings) 
- - LZMA dictionary (dictionary size is encoded in LZMA properties header)
-
-1) read LZMA properties (5 bytes) and uncompressed size (8 bytes, little-endian) to header:
-   unsigned char header[LZMA_PROPS_SIZE + 8];
-   ReadFile(inFile, header, sizeof(header)
-
-2) Allocate CLzmaDec structures (state + dictionary) using LZMA properties
-
-  CLzmaDec state;
-  LzmaDec_Constr(&state);
-  res = LzmaDec_Allocate(&state, header, LZMA_PROPS_SIZE, &g_Alloc);
-  if (res != SZ_OK)
-    return res;
-
-3) Init LzmaDec structure before any new LZMA stream. And call LzmaDec_DecodeToBuf in loop
-
-  LzmaDec_Init(&state);
-  for (;;)
-  {
-    ... 
-    int res = LzmaDec_DecodeToBuf(CLzmaDec *p, Byte *dest, SizeT *destLen, 
-    	const Byte *src, SizeT *srcLen, ELzmaFinishMode finishMode);
-    ...
-  }
-
-
-4) Free all allocated structures
-  LzmaDec_Free(&state, &g_Alloc);
-
-For full code example, look at C/LzmaUtil/LzmaUtil.c code.
-
-
-How To compress data
---------------------
-
-Compile files: LzmaEnc.h + LzmaEnc.c + Types.h +
-LzFind.c + LzFind.h + LzFindMt.c + LzFindMt.h + LzHash.h
-
-Memory Requirements:
-  - (dictSize * 11.5 + 6 MB) + state_size
-
-Lzma Encoder can use two memory allocators:
-1) alloc - for small arrays.
-2) allocBig - for big arrays.
-
-For example, you can use Large RAM Pages (2 MB) in allocBig allocator for 
-better compression speed. Note that Windows has bad implementation for 
-Large RAM Pages. 
-It's OK to use same allocator for alloc and allocBig.
-
-
-Single-call Compression with callbacks
---------------------------------------
-
-Check C/LzmaUtil/LzmaUtil.c as example, 
-
-When to use: file->file decompressing 
-
-1) you must implement callback structures for interfaces:
-ISeqInStream
-ISeqOutStream
-ICompressProgress
-ISzAlloc
-
-static void *SzAlloc(void *p, size_t size) { p = p; return MyAlloc(size); }
-static void SzFree(void *p, void *address) {  p = p; MyFree(address); }
-static ISzAlloc g_Alloc = { SzAlloc, SzFree };
-
-  CFileSeqInStream inStream;
-  CFileSeqOutStream outStream;
-
-  inStream.funcTable.Read = MyRead;
-  inStream.file = inFile;
-  outStream.funcTable.Write = MyWrite;
-  outStream.file = outFile;
-
-
-2) Create CLzmaEncHandle object;
-
-  CLzmaEncHandle enc;
-
-  enc = LzmaEnc_Create(&g_Alloc);
-  if (enc == 0)
-    return SZ_ERROR_MEM;
-
-
-3) initialize CLzmaEncProps properties;
-
-  LzmaEncProps_Init(&props);
-
-  Then you can change some properties in that structure.
-
-4) Send LZMA properties to LZMA Encoder
-
-  res = LzmaEnc_SetProps(enc, &props);
-
-5) Write encoded properties to header
-
-    Byte header[LZMA_PROPS_SIZE + 8];
-    size_t headerSize = LZMA_PROPS_SIZE;
-    UInt64 fileSize;
-    int i;
-
-    res = LzmaEnc_WriteProperties(enc, header, &headerSize);
-    fileSize = MyGetFileLength(inFile);
-    for (i = 0; i < 8; i++)
-      header[headerSize++] = (Byte)(fileSize >> (8 * i));
-    MyWriteFileAndCheck(outFile, header, headerSize)
-
-6) Call encoding function:
-      res = LzmaEnc_Encode(enc, &outStream.funcTable, &inStream.funcTable, 
-        NULL, &g_Alloc, &g_Alloc);
-
-7) Destroy LZMA Encoder Object
-  LzmaEnc_Destroy(enc, &g_Alloc, &g_Alloc);
-
-
-If callback function return some error code, LzmaEnc_Encode also returns that code.

-Single-call RAM->RAM Compression
---------------------------------
-
-Single-call RAM->RAM Compression is similar to Compression with callbacks,
-but you provide pointers to buffers instead of pointers to stream callbacks:
-
-HRes LzmaEncode(Byte *dest, SizeT *destLen, const Byte *src, SizeT srcLen,
-    CLzmaEncProps *props, Byte *propsEncoded, SizeT *propsSize, int writeEndMark, 
-    ICompressProgress *progress, ISzAlloc *alloc, ISzAlloc *allocBig);
-
-Return code:
-  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)

-LZMA Defines
-------------
-
-_LZMA_SIZE_OPT - Enable some optimizations in LZMA Decoder to get smaller executable code.
-
-_LZMA_PROB32   - It can increase the speed on some 32-bit CPUs, but memory usage for 
-                 some structures will be doubled in that case.
-
-_LZMA_UINT32_IS_ULONG  - Define it if int is 16-bit on your compiler and long is 32-bit.
-
-_LZMA_NO_SYSTEM_SIZE_T  - Define it if you don't want to use size_t type.
-
-
-C++ LZMA Encoder/Decoder 
-~~~~~~~~~~~~~~~~~~~~~~~~
-C++ LZMA code use COM-like interfaces. So if you want to use it, 
-you can study basics of COM/OLE.
-C++ LZMA code is just wrapper over ANSI-C code.
-
-
-C++ Notes
-~~~~~~~~~~~~~~~~~~~~~~~~
-If you use some C++ code folders in 7-Zip (for example, C++ code for .7z handling),
-you must check that you correctly work with "new" operator.
-7-Zip can be compiled with MSVC 6.0 that doesn't throw "exception" from "new" operator.
-So 7-Zip uses "CPP\Common\NewHandler.cpp" that redefines "new" operator:
-operator new(size_t size)
-{
-  void *p = ::malloc(size);
-  if (p == 0)
-    throw CNewException();
-  return p;
-}
-If you use MSCV that throws exception for "new" operator, you can compile without 
-"NewHandler.cpp". So standard exception will be used. Actually some code of 
-7-Zip catches any exception in internal code and converts it to HRESULT code.
-So you don't need to catch CNewException, if you call COM interfaces of 7-Zip.
