-RAM requirements for LZMA:
- for compression: (dictSize * 11.5 + 6 MB) + state_size
- for decompression: dictSize + state_size
- state_size = (4 + (1.5 << (lc + lp))) KB
- by default (lc=3, lp=0), state_size = 16 KB.
-
-LZMA properties (5 bytes) format
- Offset Size Description
- 0 1 lc, lp and pb in encoded form.
- 1 4 dictSize (little endian).

- The default value for "level" is 5.

- algo = 0 means fast 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)
