SzExtract extracts file from archive
*outBuffer must be 0 before first call for each new archive.
Extracting cache:
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.
If you use external function, you can declare these 3 cache variables
(blockIndex, outBuffer, outBufferSize) as static in that external function.
Free *outBuffer and set *outBuffer to 0, if you want to flush cache.
