-  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.
