(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) 18 19*/ 20 21#ifndef _ZLIBIOAPI64_H 22#define _ZLIBIOAPI64_H 23 24#if (!defined(_WIN32)) && (!defined(WIN32)) && (!defined(__APPLE__)) 25 26 // Linux needs this to support file operation on files larger then 4+GB 27 // But might need better if/def to select just the platforms that needs them. 28 29 #ifndef __USE_FILE_OFFSET64 30 #define __USE_FILE_OFFSET64 31 #endif 32 #ifndef __USE_LARGEFILE64 33 #define __USE_LARGEFILE64 34 #endif 35 #ifndef _LARGEFILE64_SOURCE 36 #define _LARGEFILE64_SOURCE 37 #endif 38 #ifndef _FILE_OFFSET_BIT 39 #define _FILE_OFFSET_BIT 64 40 #endif 41 42#endif 43 44#include <stdio.h> 45#include <stdlib.h> 46#include "zlib.h" 47 48#if defined(USE_FILE32API) 49#define fopen64 fopen 50#define ftello64 ftell 51#define fseeko64 fseek 52#else 53#ifdef __FreeBSD__ 54#define fopen64 fopen 55#define ftello64 ftello 56#define fseeko64 fseeko 57#endif 58#ifdef _MSC_VER 59 #define fopen64 fopen 60 #if (_MSC_VER >= 1400) && (!(defined(NO_MSCVER_FILE64_FUNC))) 61 #define ftello64 _ftelli64 62 #define fseeko64 _fseeki64 63 #else // old MSC 64 #define ftello64 ftell 65 #define fseeko64 fseek 66 #endif 67#endif 68#endif 69 70/* 71#ifndef ZPOS64_T 72 #ifdef _WIN32 73 #define ZPOS64_T fpos_t 74 #else 75 #include <stdint.h> 76 #define ZPOS64_T uint64_t 77 #endif 78#endif 79*/ 80 81#ifdef HAVE_MINIZIP64_CONF_H 82#include "mz64conf.h" 83#endif 84 85/* a type choosen by DEFINE */ 86#ifdef HAVE_64BIT_INT_CUSTOM 87typedef 64BIT_INT_CUSTOM_TYPE ZPOS64_T;
