(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 #if defined(__FreeBSD__) || defined(__OpenBSD__) || defined(__NetBSD__) \ 54 || defined(__HAIKU__) || defined(MINIZIP_FOPEN_NO_64) 55 56 #define fopen64 fopen 57 #define ftello64 ftello 58 #define fseeko64 fseeko 59 #endif 60 #ifdef _MSC_VER 61 #define fopen64 fopen 62 #if (_MSC_VER >= 1400) && (!(defined(NO_MSCVER_FILE64_FUNC))) 63 #define ftello64 _ftelli64 64 #define fseeko64 _fseeki64 65 #else // old MSC 66 #define ftello64 ftell 67 #define fseeko64 fseek 68 #endif 69 #endif 70 #endif 71 72 /* 73 #ifndef ZPOS64_T 74 #ifdef _WIN32 75 #define ZPOS64_T fpos_t 76 #else 77 #include <stdint.h> 78 #define ZPOS64_T uint64_t 79 #endif 80 #endif 81 */ 82 83 #ifdef HAVE_MINIZIP64_CONF_H 84 #include "mz64conf.h" 85 #endif 86 87 /* a type chosen by DEFINE */ 88 #ifdef HAVE_64BIT_INT_CUSTOM 89 typedef 64BIT_INT_CUSTOM_TYPE ZPOS64_T;
