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.
|
||
|
|
|
||
|
|
This calling wrapper for Wiz_SingleEntryUnzip() provides a method to pass
|
||
|
|
file lists as plain strings instead of the usual string arrays.
|
||
|
|
For VB Users only...:
|
||
|
|
|
||
|
|
int WINAPI Wiz_SingleEntryUnzpList(unsigned int ifnc, LPCSTR ExtList,
|
||
|
|
unsigned int xfnc, LPCSTR ExcList,
|
||
|
|
LPDCL lpDCL, LPUSERFUNCTIONS lpUserFunc)
|
||
|
|
|
||
|
|
ifnc = number of file names being passed. If all files are to be
|
||
|
|
extracted, then this can be zero.
|
||
|
|
ExtList = Pointer to a list of file names to be extracted, separated by
|
||
|
|
white space. If all files are to be extracted, then this should
|
||
|
|
be NULL. Parameter ifnc should have an accurate count of the
|
||
|
|
number of filenames being passed in.
|
||
|
|
xfnc = number of "file names to be excluded from processing" being
|
||
|
|
passed. If all files are to be extracted, set this to zero.
|
||
|
|
ExcList = Pointer to a list of file names to be excluded from processing.
|
||
|
|
Parameter xfnc should have an accurate count of the number of
|
||
|
|
the number of filenames being passed in.
|
||
|
|
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.
|
||
|
|
|
||
|
|
|
||
|
|
The DCL structure collects the set of option flags supported by the WinDLL
|
||
|
|
interface to control the operation of the main function calls.
|
||
|
|
The first member of this structure is now a version identifier that should
|
||
|
|
be used to check structural compatibility of a passed option struct with
|
||
|
|
the expected structure layout. The C header file containing the reference
|
||
|
|
definition of the DCL structure also provides a symbol denoting the currently
|
||
|
|
valid StructVersID:
|
||
|
|
|
||
|
|
#define UZ_DCL_STRUCTVER 0x600
|
||
|
|
|
||
|
|
The layout of the DCL structure is shown below:
|
||
|
|
|
||
|
|
typedef struct {
|
||
|
|
unsigned StructVersID = struct version id (= UZ_DCL_STRUCTVER)
|
||
|
|
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 = always overwriting existing files if TRUE
|
||
|
|
int naflag = do end-of-line translation
|
||
|
|
int nZIflag = get ZipInfo if TRUE
|
||
|
|
int B_flag = backup existing files if TRUE
|
||
|
|
int C_flag = be case insensitive if TRUE
|
||
|
|
int D_flag = controls restoration of timestamps
|
||
|
|
0 = restore all timestamps (default)
|
||
|
|
1 = skip restoration of timestamps for folders
|
||
|
|
created on behalf of directory entries in the
|
||
|
|
Zip archive
|
||
|
|
2 = do not restore any timestamps; extracted files
|
||
|
|
and directories get stamped with the current time
|
||
|
|
int U_flag = controls UTF-8 filename coding support
|
||
|
|
0 = automatic UTF-8 translation enabled (default)
|
||
|
|
1 = recognize UTF-8 coded names, but all non-ASCII
|
||
|
|
characters are "escaped" into "#Uxxxx"
|
||
|
|
2 = UTF-8 support is disabled, filename handling
|
||
|
|
works exactly as in previous UnZip versions
|
||
|
|
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.
|
||
|

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:
|

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.

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. The
|
||
|
|
replace routine may modify the content of the efnam
|
||
|
|
string buffer, but must not write beyond its fixed
|
||
|
|
size of efbufsiz bytes! (This is a potential security
|
||
|
|
leak of the windll interface.) When modifying the
|
||
|
|
efnam buffer, the replace routine should return
|
||
|
|
the status IDM_REPLACE_RENAME.
|
||
|
|
DLLPASSWORD *password = a pointer to the application's password routine.
|
||
|
|
This function should return one of the status values
|
||
|
|
IZ_PW_ENTERED (0), IZ_PW_CANCEL (-1),
|
||
|
|
IZ_PW_CANCEL_ALL (-2), IZ_PW_ERROR (5).
|
||
|
|
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 archive member it has just processed,
|
||
|
|
as well as it's original size.
|
||
|
|
DLLMESSAGE_I32 *SendApplicationMessage_i32 = variant of SendApplicationMessage
|
||
|
|
callback, for environments that do not support the
|
||
|
|
64-bit integer types required to transfer "large"
|
||
|
|
ZIP64-compatible sizes.
|
||
|
|
DLLSERVICE_I32 *ServCallBk_i32 = variant of the ServCallBk callback function,
|
||
|
|
for environments that do not support 64-bit integers.
|
||
|
|
[NOTE: The _i32 variants of the SendApplicationMessage and ServCallBk callback
|
||
|
|
functions are only called when the corresponding "regular" callback
|
||
|
|
function pointers are set to NULL. For the i386 architecture, the
|
||
|
|
"..._i32" calling interfaces are binary identical with the
|

|
|
corresponding regular __int64-aware interfaces.]

||
|
|
[NOTE: The values below are filled in only when listing the contents of an
|
||
|
|
archive.]
|
||
|
|
z_uint8 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.
|
||
|
|
z_uint8 TotalSize = value to be filled in by the dll for the total
|
||
|
|
size of all files in the archive.
|
||
|
|
z_uint8 NumMembers = total number of files in the archive.
|
||
|
|
unsigned 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.

Wiz_SingleEntryUnzip() returns a PKWARE compatible error code (0 if no
|
||
|
|
error or warning). For an explanation of the supported error codes see
|
||
|
|
the UnZip user documentation (the UnZip man page).
|
||
|
|
|
||
|
|
For examples of how the actual calls to the dll are set up in WiZ, look in
|
||
|
|
the files action.c and wizmain.c in the WiZ source directory. For a trival
|
||
|
|
example of how to load and call the dll, look in uzexampl.c and uzexampl.h.
|
||
|
|
|
||
|
|
For examples of how the actual loading and unloading of the dll's themselves
|
||
|
|
was done, look in wizmain.c in the WiZ source directory. Note that WiZ looks
|
||
|
|
specifically for a particular version number of the dll, and also expects to
|
||
|
|
find the company name to be Info-ZIP. This is to protect from getting
|
||
|
|
different versions of the dll loaded, with resulting unknown behavior.

int SkipBin, LPUSERFUNCTIONS lpUserFunc)

Pass the name of the zip file in "zip", the name of the zip entry you wish
|
||
|
|
to perform the "grep" on in "file", and the string you wish to look for in
|
||
|
|
"pattern". There are four possible options for cmd:
|
||
|
|
|
||
|
|
0 => case insensitive search
|
||
|
|
1 => case sensitive search
|
||
|
|
2 => case insensitive search, whole words only
|
||
|
|
3 => case sensitive search, whole words only
|
||
|
|
|
||
|
|
If SkipBin is TRUE, then any binary (loosely interpreted) files will be
|
||
|
|
ignored.
|
||
|
|
|
||
|
|
lpUserFunc is a pointer to a USERFUNCTION structure as shown above.
|
||
|
|
|
||
|
|
UzpGrep returns:
|
||
|
|
|
||
|
|
-1 => error such as unable to allocate memory, unable to find file, etc.
|
||
|
|
0 => match not found, based on the search criteria
|
||
|
|
1 => match found, based on the search criteria
|
||
|
|
|
||
|
|
There is an additional function call that does not specifically deal with
|
||
|
|
"unzipping", but is a quite useful function that is currently used in Wiz
|
||
|
|
itself in several places. This call is currently only available in the
|
||
|
|
static library, not in the DLL.
|
||
|
|
|
||
|
|
Match the pattern (wildcard) against the string (fixed):
|
||
|
|
|
||
|
|
match(const char *string, const char *pattern, int ignore_case);
|
||
|
|
|
||
|
|
or, when UnZips WILD_SEP_AT_DIR compile-time option was set:
|
||
|
|
|
||
|
|
match(const char *string, const char *pattern, int ignore_case, int sepc);
|
||
|
|
|
||
|
|
returns TRUE if string matches pattern, FALSE otherwise. In the pattern:
|
||
|
|
|
||
|
|
`*' matches any sequence of characters (zero or more)
|
||
|
|
`?' matches any single character
|
||
|
|
[SET] matches any character in the specified set,
|
||
|
|
[!SET] or [^SET] matches any character not in the specified set.
|
||
|
|
|
||
|
|
In case the code was compiled with WILD_STOP_AT_DIR enabled, the pattern
|
||
|
|
wildcard functionality is modified as follows:
|
||
|
|
`*' matches any sequence of characters (zero or more) until the first
|
||
|
|
occurence of the separating character denoted by `sepc'
|
||
|
|
`**' matches any sequence of characters (zero or more)
|
||
|
|
|
||
|
|
A set is composed of characters or ranges; a range looks like ``character
|
||
|
|
hyphen character'' (as in 0-9 or A-Z). [0-9a-zA-Z_] is the minimal set of
|
||
|
|
characters allowed in the [..] pattern construct. Other characters are
|
||
|
|
allowed (i.e., 8-bit characters) if your system will support them.
|
||
|
|
|
||
|
|
To suppress the special syntactic significance of any of ``[]*?!^-\'', in-
|
||
|
|
side or outside a [..] construct, and match the character exactly, precede
|
||
|
|
it with a ``\'' (backslash).
|
||
|
|
|
||
|
|
The remaining functions are linked together. Their use would be as
|
||
|
|
follows (explanations for each function are shown further below):
|
||
|
|
|
||
|
|
#include "windll.h"
|
||
|
|
#include "structs.h"
|
||
|
|
MyApiCallingRoutine()
|
||
|
|
{
|
||
|
|
CREATEGLOBALS();
|
||
|
|
.
|
||
|
|
.
|
||
|
|
.
|
||
|
|
Wiz_Init(pG, lpUserFunctions); /* Set up user functions */
|
||
|
|
/* zvoid *pG, LPUSERFUNCTIONS lpUserFunctions */
|
||
|
|
.
|
||
|
|
.
|
||
|
|
do {
|
||
|
|
.
|
||
|
|
.
|
||
|
|
Wiz_SetOpts(pG, lpDCL); /* Set up unzipping options */
|
||
|
|
/* zvoid *pG, LPDCL lpDCL */
|
||
|
|
.
|
||
|
|
.
|
||
|
|
Wiz_Unzip(pG, ifnc, ifnv, xfnc, xfnv); /* Unzip files */
|
||
|
|
.
|
||
|
|
.
|
||
|
|
} while (!finished_condition)
|
||
|
|
.
|
||
|
|
.
|
||
|
|
DESTROYGLOBALS();
|
||
|
|
}
|
||
|
|
|
||
|
|
Each entry point is as defined below:
|
||
|
|
|
||
|
|
BOOL WINAPI Wiz_Init(zvoid *, LPUSERFUNCTIONS);
|
||
|
|
|
||
|
|
BOOL WINAPI Wiz_SetOpts(zvoid *, LPDCL);
|
||
|
|
|
||
|
|
int WINAPI Wiz_Unzip(zvoid *, int, char **, int, char **);
|
||
|
|
|
||
|
|
Note that you should use either Wiz_SingleEntryUnzip OR the series of calls
|
||
|
|
described above. Using both, depending on how you do it, could cause
|
||
|
|
problems. The series of "lower level" gives you more freedom to add additional
|
||
|
|
functionalities, whereas the single-entry api is easier to use. When using
|
||
|
|
the "series" of calls, make sure that Wiz_SetOpts and Wiz_Unzip are always
|
||
|
|
used together! When successfully called, Wiz_SetOpts has allocated some
|
||
|
|
internal structures which are in turn free'd by Wiz_Unzip.
