Tachenov to allow QIODevice API usage. 10 11 For more info read MiniZip_info.txt 12 13 Changes 14 15 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) 16 Oct-2009 - Change to fseeko64, ftello64 and fopen64 so large files would work on linux. 17 More if/def section may be needed to support other platforms 18 Oct-2009 - Defined fxxxx64 calls to normal fopen/ftell/fseek so they would compile on windows. 19 (but you should use iowin32.c for windows instead) 20 21 */ 22 23 #ifndef _ZLIBIOAPI64_H 24 #define _ZLIBIOAPI64_H 25 26 #if (!defined(_WIN32)) && (!defined(WIN32)) 27 28 // Linux needs this to support file operation on files larger then 4+GB 29 // But might need better if/def to select just the platforms that needs them. 30 31 #ifndef __USE_FILE_OFFSET64 32 #define __USE_FILE_OFFSET64 33 #endif 34 #ifndef __USE_LARGEFILE64 35 #define __USE_LARGEFILE64 36 #endif 37 #ifndef _LARGEFILE64_SOURCE 38 #define _LARGEFILE64_SOURCE 39 #endif 40 #ifndef _FILE_OFFSET_BIT 41 #define _FILE_OFFSET_BIT 64 42 #endif 43 #endif 44 45 #include <stdio.h> 46 #include <stdlib.h> 47 #include "zlib.h" 48 49 #if defined(USE_FILE32API) 50 #define fopen64 fopen 51 #define ftello64 ftell 52 #define fseeko64 fseek 53 #else 54 #ifdef _MSC_VER 55 #define fopen64 fopen 56 #if (_MSC_VER >= 1400) && (!(defined(NO_MSCVER_FILE64_FUNC))) 57 #define ftello64 _ftelli64 58 #define fseeko64 _fseeki64 59 #else // old MSC 60 #define ftello64 ftell 61 #define fseeko64 fseek 62 #endif 63 #endif 64 #endif 65 66 /* 67 #ifndef ZPOS64_T 68 #ifdef _WIN32 69 #define ZPOS64_T fpos_t 70 #else 71 #include <stdint.h> 72 #define ZPOS64_T uint64_t 73 #endif 74 #endif 75 */ 76 77 #ifdef HAVE_MINIZIP64_CONF_H 78 #include "mz64conf.h" 79 #endif 80 81 /* a type choosen by DEFINE */ 82 #ifdef HAVE_64BIT_INT_CUSTOM 83 typedef 64BIT_INT_CUSTOM_TYPE ZPOS64_T;
