/* ioapi.h -- IO base function header for compress/uncompress .zip part of the MiniZip project - ( http://www.winimage.com/zLibDll/minizip.html ) Copyright (C) 1998-2010 Gilles Vollant (minizip) ( http://www.winimage.com/zLibDll/minizip.html ) Modifications for Zip64 support Copyright (C) 2009-2010 Mathias Svensson ( http://result42.com ) For more info read MiniZip_info.txt Changes 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) 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 #include "config.h" // Must be first to include things like _FILE_OFFSET_BITS #include #include #include "zlib.h" #ifdef HAVE_MINIZIP64_CONF_H #include "mz64conf.h" #endif #ifdef HAVE_STDINT_H #include "stdint.h" typedef uint64_t ZPOS64_T; #else #if defined(HAVE__FSEEKI64) typedef unsigned __int64 ZPOS64_T; #else typedef unsigned long long int ZPOS64_T; #endif #endif /* Maximum unsigned 32-bit value used as placeholder for zip64 */ #define MAXU32 0xffffffff #ifdef __cplusplus extern "C" { #endif #define ZLIB_FILEFUNC_SEEK_CUR (1) #define ZLIB_FILEFUNC_SEEK_END (2) #define ZLIB_FILEFUNC_SEEK_SET (0) #define ZLIB_FILEFUNC_MODE_READ (1) #define ZLIB_FILEFUNC_MODE_WRITE (2) #define ZLIB_FILEFUNC_MODE_READWRITEFILTER (3) #define ZLIB_FILEFUNC_MODE_EXISTING (4) #define ZLIB_FILEFUNC_MODE_CREATE (8) #ifndef ZCALLBACK #if (defined(WIN32) || defined(_WIN32) || defined (WINDOWS) || defined (_WINDOWS)) && defined(CALLBACK) && defined (USEWINDOWS_CALLBACK) #define ZCALLBACK CALLBACK #else #define ZCALLBACK #endif #endif #ifndef OF #define OF(x) x #endif typedef voidpf (ZCALLBACK *open_file_func) OF((voidpf opaque, const char* filename, int mode)); typedef uLong (ZCALLBACK *read_file_func) OF((voidpf opaque, voidpf stream, void* buf, uLong size)); typedef uLong (ZCALLBACK *write_file_func) OF((voidpf opaque, voidpf stream, const void* buf, uLong size)); typedef int (ZCALLBACK *close_file_func) OF((voidpf opaque, voidpf stream)); typedef int (ZCALLBACK *testerror_file_func) OF((voidpf opaque, voidpf stream)); typedef long (ZCALLBACK *tell_file_func) OF((voidpf opaque, voidpf stream)); typedef long (ZCALLBACK *seek_file_func) OF((voidpf opaque, voidpf stream, uLong offset, int origin)); typedef voidpf (ZCALLBACK *clone_file_func) OF((voidpf opaque, voidpf stream)); /* here is the "old" 32 bits structure structure */ typedef struct zlib_filefunc_def_s { open_file_func zopen_file; read_file_func zread_file; write_file_func zwrite_file; tell_file_func ztell_file; seek_file_func zseek_file; close_file_func zclose_file; testerror_file_func zerror_file; voidpf opaque; clone_file_func zclone_file; } zlib_filefunc_def; typedef ZPOS64_T (ZCALLBACK *tell64_file_func) OF((voidpf opaque, voidpf stream)); typedef long (ZCALLBACK *seek64_file_func) OF((voidpf opaque, voidpf stream, ZPOS64_T offset, int origin)); typedef voidpf (ZCALLBACK *open64_file_func) OF((voidpf opaque, const void* filename, int mode)); typedef struct zlib_filefunc64_def_s { open64_file_func zopen64_file; read_file_func zread_file; write_file_func zwrite_file; tell64_file_func ztell64_file; seek64_file_func zseek64_file; close_file_func zclose_file; testerror_file_func zerror_file; voidpf opaque; clone_file_func zclone_file; } zlib_filefunc64_def; void fill_fopen64_filefunc OF((zlib_filefunc64_def* pzlib_filefunc_def)); void fill_fopen_filefunc OF((zlib_filefunc_def* pzlib_filefunc_def)); /* now internal definition, only for zip.c and unzip.h */ typedef struct zlib_filefunc64_32_def_s { zlib_filefunc64_def zfile_func64; open_file_func zopen32_file; tell_file_func ztell32_file; seek_file_func zseek32_file; clone_file_func zclone_file; } zlib_filefunc64_32_def; #define ZREAD64(filefunc,filestream,buf,size) ((*((filefunc).zfile_func64.zread_file)) ((filefunc).zfile_func64.opaque,filestream,buf,size)) #define ZWRITE64(filefunc,filestream,buf,size) ((*((filefunc).zfile_func64.zwrite_file)) ((filefunc).zfile_func64.opaque,filestream,buf,size)) //#define ZTELL64(filefunc,filestream) ((*((filefunc).ztell64_file)) ((filefunc).opaque,filestream)) //#define ZSEEK64(filefunc,filestream,pos,mode) ((*((filefunc).zseek64_file)) ((filefunc).opaque,filestream,pos,mode)) #define ZCLOSE64(filefunc,filestream) ((*((filefunc).zfile_func64.zclose_file)) ((filefunc).zfile_func64.opaque,filestream)) #define ZERROR64(filefunc,filestream) ((*((filefunc).zfile_func64.zerror_file)) ((filefunc).zfile_func64.opaque,filestream)) #define ZCLONE64(filefunc,filestream) ((*((filefunc).zfile_func64.zclone_file)) ((filefunc).zfile_func64.opaque,filestream)) voidpf call_zopen64 OF((const zlib_filefunc64_32_def* pfilefunc,const void*filename,int mode)); long call_zseek64 OF((const zlib_filefunc64_32_def* pfilefunc,voidpf filestream, ZPOS64_T offset, int origin)); ZPOS64_T call_ztell64 OF((const zlib_filefunc64_32_def* pfilefunc,voidpf filestream)); void fill_zlib_filefunc64_32_def_from_filefunc32(zlib_filefunc64_32_def* p_filefunc64_32,const zlib_filefunc_def* p_filefunc32); #define ZOPEN64(filefunc,filename,mode) (call_zopen64((&(filefunc)),(filename),(mode))) #define ZTELL64(filefunc,filestream) (call_ztell64((&(filefunc)),(filestream))) #define ZSEEK64(filefunc,filestream,pos,mode) (call_zseek64((&(filefunc)),(filestream),(pos),(mode))) #ifdef __cplusplus } #endif #endif
