 /* ioapi.h -- IO base function header for compress/uncompress .zip
-   files using zlib + zip or unzip API
+   part of the MiniZip project - ( http://www.winimage.com/zLibDll/minizip.html )
 
-   Version 1.01e, February 12th, 2005
+         Copyright (C) 1998-2010 Gilles Vollant (minizip) ( http://www.winimage.com/zLibDll/minizip.html )
+
+         Modifications for Zip64 support 
+         Copyright (C) 2009-2010 Mathias Svensson ( http://result42.com )
+
+         For more info read MiniZip_info.txt
+
+         Changes
+
+    Oct-2009 - Defined ZPOS64_T to fpos_t on windows and u_int64_t on linux. (might need to find a better why for this)
+    Oct-2009 - Change to fseeko64, ftello64 and fopen64 so large files would work on linux.
+               More if/def section may be needed to support other platforms
+    Oct-2009 - Defined fxxxx64 calls to normal fopen/ftell/fseek so they would compile on windows. 
+                          (but you should use iowin32.c for windows instead)
