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) |

// Linux needs this to support file operation on files larger then 4+GB |

// But might need better if/def to select just the platforms that needs them. |
