11 | Changes | |
12 | ||
13 | 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) | |
14 | Oct-2009 - Change to fseeko64, ftello64 and fopen64 so large files would work on linux. | |
15 | More if/def section may be needed to support other platforms | |
16 | Oct-2009 - Defined fxxxx64 calls to normal fopen/ftell/fseek so they would compile on windows. | |
17 | (but you should use iowin32.c for windows instead) | |
