-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). |

- LZMA Encoder will use defult values for any parameter, if it is |

- 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) |
