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.
