| 17 *outBuffer, | |
| 18 *outBufferSize | |
| 19 You can consider "*outBuffer" as cache of solid block. If your archive is so
lid, | |
| 20 it will increase decompression speed. | |
| 21 | |
| 22 If you use external function, you can declare these 3 cache variables | |
| 23 (blockIndex, outBuffer, outBufferSize) as static in that external function. | |
| 24 | |
| 25 Free *outBuffer and set *outBuffer to 0, if you want to flush cache. | |
