+    

+  Interface-2 : Direct output buffer:

+    Use it, if you know exact size of decoded data, and you need

+    whole xz unpacked data in one output buffer.

+    xz unpacker doesn't allocate additional buffer for lzma2 dictionary in that mode.

+    {

+      XzUnpacker_SetOutBufMode(); // to set output buffer and size

+      for()

+        XzUnpacker_Code(); // (dest = NULL) in XzUnpacker_Code()

+    }

+

+  Interface-3 : Direct output buffer : One call full decoding

+    It unpacks whole input buffer to output buffer in one call.
