(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 47 #ifdef USE_LOCAL_HEADERS 48 #include "zlib.h" 49 #else 50 #include <zlib.h> 51 #endif 52 53 #if defined(USE_FILE32API) 54 #define fopen64 fopen 55 #define ftello64 ftell 56 #define fseeko64 fseek 57 #else 58 #if defined(__FreeBSD__) || defined(__OpenBSD__) || defined(__NetBSD__) || defined(__DragonFly__) 59 #define fopen64 fopen 60 #define ftello64 ftello 61 #define fseeko64 fseeko 62 #endif 63 #ifdef _MSC_VER 64 #define fopen64 fopen 65 #if (_MSC_VER >= 1400) && (!(defined(NO_MSCVER_FILE64_FUNC))) 66 #define ftello64 _ftelli64 67 #define fseeko64 _fseeki64 68 #else // old MSC 69 #define ftello64 ftell 70 #define fseeko64 fseek 71 #endif 72 #endif 73 #endif 74 75 /* 76 #ifndef ZPOS64_T 77 #ifdef _WIN32 78 #define ZPOS64_T fpos_t 79 #else 80 #include <stdint.h> 81 #define ZPOS64_T uint64_t 82 #endif 83 #endif 84 */ 85 86 #ifdef HAVE_MINIZIP64_CONF_H 87 #include "mz64conf.h" 88 #endif 89 90 /* a type choosen by DEFINE */ 91 #ifdef HAVE_64BIT_INT_CUSTOM 92 typedef 64BIT_INT_CUSTOM_TYPE ZPOS64_T;
