| 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) |
