There are now several entry points to the dll. There is a single "unzipping" entry point of: int WINAPI Wiz_SingleEntryUnzip(int ifnc, char **ifnv, int xfnc, char **xfnv, LPDCL lpDCL, LPUSERFUNCTIONS lpUserFunc) where the arguments are: ifnc = number of file names being passed. If all files are to be extracted, then this can be zero. ifnv = file names to be unarchived. Wildcard patterns are recognized and expanded. If all files are to be extracted, then this can be NULL. xfnc = number of "file names to be excluded from processing" being passed. If all files are to be extracted, set this to zero. xfnv = file names to be excluded from the unarchiving process. Wildcard characters are allowed and expanded. If all files are to be extracted, set this argument to NULL. lpDCL = pointer to a structure with the flags for setting the various options, as well as the zip file name. lpUserFunc = pointer to a structure that contains pointers to functions in the calling application, as well as sizes passed back to the calling application etc. See below for a detailed description of all the parameters. The DCL structure is shown below: typedef struct { int ExtractOnlyNewer = true for "update" without interaction (extract only newer/new files, without queries) int SpaceToUnderscore = true if convert space to underscore int PromptToOverwrite = true if prompt to overwrite is wanted int fQuiet = quiet flag: 0 = all messages, 1 = few messages, 2 = no messages int ncflag = write to stdout if true int ntflag = test zip file int nvflag = verbose listing int nfflag = "freshen" (replace existing files by newer versions) int nzflag = display zip file comment int ndflag = controls (sub)directory recreation during extraction 0 = junk paths from filenames 1 = "safe" usage of paths in filenames (skip "../") 2 = allow also unsafe path components (dir traversal) int noflag = true if you are to always overwrite existing files int naflag = do end-of-line translation int nZIflag = get ZipInfo if TRUE int C_flag = be case insensitive if TRUE int fPrivilege = 1 => restore ACLs in user mode, 2 => try to use privileges for restoring ACLs LPSTR lpszZipFN = zip file name LPSTR lpszExtractDir = directory to extract to. This should be NULL if you are extracting to the current directory. } DCL, far * LPDCL; REMARKS: The four extract-mode flags ExtractOnlyNewer, nfflag, PromptToOverwrite, and noflag control which of the selected archive entries are actually processed. They are mapped to UnZip's command line qualifiers "-u", "-f", "-o", "-n" according to the following decision matrix: _____________________________________________________________________ | UnZip 1)|| Extract- | nfflag | noflag | PrompTo- | lpUserFunc | | options || OnlyNewer | | | Overwrite | ->replape() | ===================================================================== | none 2) || false | false | false | true |queryfunc() 5)| | -o || false | false | true | false | N/A | | -n || false | false | false | false | N/A | |---------||-----------|--------|--------|-----------|--------------| | -u || true | false | false | true |queryfunc() 5)| | -uo || true | false | true | false | N/A | | -un 3) || true | false | false | false | N/A | |---------||-----------|--------|--------|-----------|--------------| | -f || N/A | true | false | true |queryfunc() 5)| | -fo || N/A | true | true | false | N/A | | -fn 4) || N/A | true | false | false | N/A | --------------------------------------------------------------------- Legend: true: integer number <> 0 false: integer number 0 N/A: not applicable, could be set to any value NOTES: 1) The UnZip options are explained in the generic UnZip manual, see "unzip.txt" or "man/unzip.1". 2) no options from the set "ufno" are specified. 3) -un is functionally equivalent to -n 4) -fn is functionally equivalent to "do nothing", so this combination does not make sense. 5) queryfunc() is a callback function provided by the caller of the unzip dll that may return one of the following result keys: IDM_REPLACE_NO, IDM_REPLACE_YES, IDM_REPLACE_ALL, IDM_REPLACE_NONE, IDM_REPLACE_RENAME (IDM_REPLACE_TEXT, IDM_REPLACE_HELP are defined but not used) UnZip's internal code treats a "NULL" lpUserFunc->replace() function pointer as "{return IDM_REPLACE_NONE}". However, currently, the windll interface checks for this function pointer to be not NULL and signals a fatal error if this condition is not fulfilled. The typedef's for the function pointers in the structure USERFUNCTIONS are shown immediately below. typedef unsigned short ush; typedef int (WINAPI DLLPRNT) (LPSTR, unsigned long); typedef int (WINAPI DLLPASSWORD) (LPSTR, int, LPCSTR, LPCSTR); typedef int (WINAPI DLLSERVICE) (LPSTR, unsigned long); typedef void (WINAPI DLLSND) (void); typedef int (WINAPI DLLREPLACE)(LPSTR); typedef void (WINAPI DLLMESSAGE)(unsigned long, unsigned long, unsigned, unsigned, unsigned, unsigned, unsigned, unsigned, char, LPSTR, LPSTR, unsigned long, char); Structure USERFUNCTIONS typedef struct { DLLPRNT *print; = a pointer to the application's print routine. DLLSND *sound; = a pointer to the application's sound routine. This can be NULL if your application doesn't use sound. DLLREPLACE *replace = a pointer to the application's replace routine. DLLPASSWORD *password = a pointer to the application's password routine. DLLMESSAGE *SendApplicationMessage = a pointer to the application's routine for displaying information about specific files in the archive. Used for listing the contents of an archive. DLLSERVICE *ServCallBk = Callback function designed to be used for allowing the application to process Windows messages, or canceling the operation, as well as giving the option of a progress indicator. If this function returns a non-zero value, then it will terminate what it is doing. It provides the application with the name of the name of the archive member it has just processed, as well as it's original size. NOTE: The values below are filled in only when listing the contents of an archive. unsigned long TotalSizeComp = value to be filled in by the dll for the compressed total size of the archive. Note this value does not include the size of the archive header and central directory list. unsigned long TotalSize = value to be filled in by the dll for the total size of all files in the archive. unsigned long CompFactor = value to be filled in by the dll for the overall compression factor. This could actually be computed from the other values, but it is available. unsigned long NumMembers = total number of files in the archive. WORD cchComment; = flag to be set if archive has a comment } USERFUNCTIONS, fa
