(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) */ #ifndef _ZLIBIOAPI64_H #define _ZLIBIOAPI64_H #if (!defined(_WIN32)) && (!defined(WIN32)) && (!defined(__APPLE__)) // 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. #ifndef __USE_FILE_OFFSET64 #define __USE_FILE_OFFSET64 #endif #ifndef __USE_LARGEFILE64 #define __USE_LARGEFILE64 #endif #ifndef _LARGEFILE64_SOURCE #define _LARGEFILE64_SOURCE #endif #ifndef _FILE_OFFSET_BIT #define _FILE_OFFSET_BIT 64 #endif #endif #include <stdio.h> #include <stdlib.h> #include "zlib.h" #if defined(USE_FILE32API) #define fopen64 fopen #define ftello64 ftell #define fseeko64 fseek #else #if defined(__FreeBSD__) || defined(__OpenBSD__) || defined(__NetBSD__) || defined(__HAIKU__) || defined(MINIZIP_FOPEN_NO_64) #define fopen64 fopen #define ftello64 ftello #define fseeko64 fseeko #endif #ifdef _MSC_VER #define fopen64 fopen #if (_MSC_VER >= 1400) && (!(defined(NO_MSCVER_FILE64_FUNC))) #define ftello64 _ftelli64 #define fseeko64 _fseeki64 #else // old MSC #define ftello64 ftell #define fseeko64 fseek #endif #endif #endif /* #ifndef ZPOS64_T #ifdef _WIN32 #define ZPOS64_T fpos_t #else #include <stdint.h> #define ZPOS64_T uint64_t #endif #endif */ #ifdef HAVE_MINIZIP64_CONF_H #include "mz64conf.h" #endif /* a type chosen by DEFINE */ #ifdef HAVE_64BIT_INT_CUSTOM typedef 64BIT_INT_CUSTOM_TYPE ZPOS64_T;
