7z ANSI-C Decoder 4.62
|
||||
----------------------
|
||||
|
||||
7z ANSI-C provides 7z/LZMA decoding.
|
||||
7z ANSI-C version is simplified version ported from C++ code.
|
||||
|
||||
LZMA is default and general compression method of 7z format
|
||||
in 7-Zip compression program (www.7-zip.org). LZMA provides high
|
||||
compression ratio and very fast decompression.
|
||||
|
||||
|
||||
LICENSE
|
||||
-------
|
||||
|
||||
7z ANSI-C Decoder is part of the LZMA SDK.
|
||||
LZMA SDK is written and placed in the public domain by Igor Pavlov.

How To Use
|
||||
----------
|
||||
|
||||
You must download 7-Zip program from www.7-zip.org.
|
||||
|
||||
You can create .7z archive with 7z.exe or 7za.exe:
|
||||
|
||||
7za.exe a archive.7z *.htm -r -mx -m0fb=255
|
||||
|
||||
If you have big number of files in archive, and you need fast extracting,
|
||||
you can use partly-solid archives:
|
||||
|
||||
7za.exe a archive.7z *.htm -ms=512K -r -mx -m0fb=255 -m0d=512K
|
||||
|
||||
In that example 7-Zip will use 512KB solid blocks. So it needs to decompress only
|
||||
512KB for extracting one file from such archive.
|
||||
|
||||
|
||||
Limitations of current version of 7z ANSI-C Decoder
|
||||
---------------------------------------------------
|
||||
|
||||
- It reads only "FileName", "Size", "LastWriteTime" and "CRC" information for each file in archive.
|
||||
- It supports only LZMA and Copy (no compression) methods with BCJ or BCJ2 filters.
|
||||
- It converts original UTF-16 Unicode file names to UTF-8 Unicode file names.
|
||||
|
||||
These limitations will be fixed in future versions.
|
||||
|
||||
|
||||
Using 7z ANSI-C Decoder Test application:
|
||||
-----------------------------------------
|
||||
|
||||
Usage: 7zDec <command> <archive_name>
|
||||
|
||||
<Command>:
|
||||
e: Extract files from archive
|
||||
l: List contents of archive
|
||||
t: Test integrity of archive
|
||||
|
||||
Example:
|
||||
|
||||
7zDec l archive.7z
|
||||
|
||||
lists contents of archive.7z
|
||||
|
||||
7zDec e archive.7z
|
||||
|
||||
extracts files from archive.7z to current folder.
|
||||
|
||||
|
||||
How to use .7z Decoder
|
||||
----------------------
|
||||
|
||||
Memory allocation
|
||||
~~~~~~~~~~~~~~~~~
|
||||
|
||||
7z Decoder uses two memory pools:
|
||||
1) Temporary pool
|
||||
2) Main pool
|
||||
Such scheme can allow you to avoid fragmentation of allocated blocks.
|
||||
|
||||
|
||||
Steps for using 7z decoder
|
||||
--------------------------
|
||||
|
||||
Use code at 7zMain.c as example.
|
||||
|
||||
1) Declare variables:
|
||||
inStream /* implements ILookInStream interface */
|
||||
CSzArEx db; /* 7z archive database structure */
|
||||
ISzAlloc allocImp; /* memory functions for main pool */
|
||||
ISzAlloc allocTempImp; /* memory functions for temporary pool */
|
||||
|
||||
2) call CrcGenerateTable(); function to initialize CRC structures.
|
||||
|
||||
3) call SzArEx_Init(&db); function to initialize db structures.
|
||||
|
||||
4) call SzArEx_Open(&db, inStream, &allocMain, &allocTemp) to open archive
|
||||
|
||||
This function opens archive "inStream" and reads headers to "db".
|
||||
All items in "db" will be allocated with "allocMain" functions.
|
||||
SzArEx_Open function allocates and frees temporary structures by "allocTemp" functions.
|
||||
|
||||
5) List items or Extract items
|
||||
|
||||
Listing code:
|
||||
~~~~~~~~~~~~~
|
||||
{
|
||||
UInt32 i;
|
||||
for (i = 0; i < db.db.NumFiles; i++)
|
||||
{
|
||||
CFileItem *f = db.db.Files + i;
|
||||
printf("%10d %s\n", (int)f->Size, f->Name);
|
||||
}
|
||||
}
|
||||
|
||||
Extracting code:
|
||||
~~~~~~~~~~~~~~~~
|
||||
|
||||
SZ_RESULT SzAr_Extract(
|
||||
CArchiveDatabaseEx *db,
|
||||
ILookInStream *inStream,
|
||||
UInt32 fileIndex, /* index of file */
|
||||
UInt32 *blockIndex, /* index of solid block */
|
||||
Byte **outBuffer, /* pointer to pointer to output buffer (allocated with allocMain) */
|
||||
size_t *outBufferSize, /* buffer size for output buffer */
|
||||
size_t *offset, /* offset of stream for required file in *outBuffer */
|
||||
size_t *outSizeProcessed, /* size of file in *outBuffer */
|
||||
ISzAlloc *allocMain,
|
||||
ISzAlloc *allocTemp);
|
||||
|
||||
If you need to decompress more than one file, you can send these values from previous call:
|
||||
blockIndex,
|
||||
outBuffer,
|
||||
outBufferSize,
|
||||
You can consider "outBuffer" as cache of solid block. If your archive is solid,
|
||||
it will increase decompression speed.
|
||||
|
||||
After decompressing you must free "outBuffer":
|
||||
allocImp.Free(outBuffer);
|
||||
|
||||
6) call SzArEx_Free(&db, allocImp.Free) to free allocated items in "db".
|
||||
|
||||
|
||||
|
||||
|
||||
Memory requirements for .7z decoding
|
||||
------------------------------------
|
||||
|
||||
Memory usage for Archive opening:
|
||||
- Temporary pool:
|
||||
- Memory for uncompressed .7z headers
|
||||
- some other temporary blocks
|
||||
- Main pool:
|
||||
- Memory for database:
|
||||
Estimated size of one file structures in solid archive:
|
||||
- Size (4 or 8 Bytes)
|
||||
- CRC32 (4 bytes)
|
||||
- LastWriteTime (8 bytes)
|
||||
- Some file information (4 bytes)
|
||||
- File Name (variable length) + pointer + allocation structures
|
||||
|
||||
Memory usage for archive Decompressing:
|
||||
- Temporary pool:
|
||||
- Memory for LZMA decompressing structures
|
||||
- Main pool:
|
||||
- Memory for decompressed solid block
|
||||
- Memory for temprorary buffers, if BCJ2 fileter is used. Usually these
|
||||
temprorary buffers can be about 15% of solid block size.
|
||||
|
||||
|
||||
7z Decoder doesn't allocate memory for compressed blocks.
|
||||
Instead of this, you must allocate buffer with desired
|
||||
size before calling 7z Decoder. Use 7zMain.c as example.
|
||||
|
||||
|
||||
Defines
|
||||
-------
|
||||
|
||||
_SZ_ALLOC_DEBUG - define it if you want to debug alloc/free operations to stderr.

Notes about Notation and encoding
|
||||
---------------------------------
|
||||
|
||||
7z uses little endian encoding.
|
||||
|
||||
7z archive format has optional headers that are marked as
|
||||
[]
|
||||
Header
|
||||
[]
|
||||
|
||||
REAL_UINT64 means real UINT64.
|
||||
|
||||
UINT64 means real UINT64 encoded with the following scheme:
|
||||
|
||||
Size of encoding sequence depends from first byte:
|
||||
First_Byte Extra_Bytes Value
|
||||
(binary)
|
||||
0xxxxxxx : ( xxxxxxx )
|
||||
10xxxxxx BYTE y[1] : ( xxxxxx << (8 * 1)) + y
|
||||
110xxxxx BYTE y[2] : ( xxxxx << (8 * 2)) + y
|
||||
...
|
||||
1111110x BYTE y[6] : ( x << (8 * 6)) + y

level - compression level: 0 <= level <= 9, the default value for "level" is 5.
|

|

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, for level = 5.
|
||||
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.

For better compression ratio dictSize must be >= inSize.

SZ_FILTER_YES - x86 Filter

2 passes when FILTER_NO provides better compression.

3 passes when FILTER_YES provides better compression.

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)
