source: s10k/CommonLibs/zlib-1.2.8/contrib/minizip/ioapi.h @ 1096

Last change on this file since 1096 was 1096, checked in by s10k, 22 months ago

Added zlib, quazip, basicxmlsyntaxhighlighter, conditionalsemaphore and linenumberdisplay libraries. zlib and quazip are pre-compiled, but you can compile them yourself, just delete the dll files (or equivalent binary files to your OS)

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)
