Move zlib to a submodule, informed by @tasiaiso's #45. And fixup [archive] dist/tildefriends-0.0.18-wip.tar.xz
[cp] TildeFriends-x86-0.0.18-wip.apk [cp] TildeFriends-arm-0.0.18-wip.apk [cp] TildeFriends-0.0.18-wip.ipa to support it.

Frequently Asked Questions about zlib
|
|
||||||
|
|
||||||
|
|
||||||
If your question is not there, please check the zlib home page
|
|
||||||
http://zlib.net/ which may have more recent information.
|
|
||||||
The latest zlib FAQ is at http://zlib.net/zlib_faq.html
|
|
||||||
|
|
||||||
|
|
||||||
1. Is zlib Y2K-compliant?
|
|
||||||
|
|
||||||
Yes. zlib doesn't handle dates.
|
|
||||||
|
|
||||||
2. Where can I get a Windows DLL version?
|
|
||||||
|
|
||||||
The zlib sources can be compiled without change to produce a DLL. See the
|
|
||||||
file win32/DLL_FAQ.txt in the zlib distribution.
|
|
||||||
|
|
||||||
3. Where can I get a Visual Basic interface to zlib?
|
|
||||||
|
|
||||||
See
|
|
||||||
* http://marknelson.us/1997/01/01/zlib-engine/
|
|
||||||
* win32/DLL_FAQ.txt in the zlib distribution
|
|
||||||
|
|
||||||
4. compress() returns Z_BUF_ERROR.
|
|
||||||
|
|
||||||
Make sure that before the call of compress(), the length of the compressed
|
|
||||||
buffer is equal to the available size of the compressed buffer and not
|
|
||||||
zero. For Visual Basic, check that this parameter is passed by reference
|
|
||||||
("as any"), not by value ("as long").
|
|
||||||
|
|
||||||
5. deflate() or inflate() returns Z_BUF_ERROR.
|
|
||||||
|
|
||||||
Before making the call, make sure that avail_in and avail_out are not zero.
|
|
||||||
When setting the parameter flush equal to Z_FINISH, also make sure that
|
|
||||||
avail_out is big enough to allow processing all pending input. Note that a
|
|
||||||
Z_BUF_ERROR is not fatal--another call to deflate() or inflate() can be
|
|
||||||
made with more input or output space. A Z_BUF_ERROR may in fact be
|
|
||||||
unavoidable depending on how the functions are used, since it is not
|
|
||||||
possible to tell whether or not there is more output pending when
|
|
||||||
strm.avail_out returns with zero. See http://zlib.net/zlib_how.html for a
|
|
||||||
heavily annotated example.
|
|
||||||
|
|
||||||
6. Where's the zlib documentation (man pages, etc.)?
|
|
||||||
|
|
||||||
It's in zlib.h . Examples of zlib usage are in the files test/example.c
|
|
||||||
and test/minigzip.c, with more in examples/ .
|
|
||||||
|
|
||||||
7. Why don't you use GNU autoconf or libtool or ...?
|
|
||||||
|
|
||||||
Because we would like to keep zlib as a very small and simple package.
|
|
||||||
zlib is rather portable and doesn't need much configuration.
|
|
||||||
|
|
||||||
8. I found a bug in zlib.
|
|
||||||
|
|
||||||
Most of the time, such problems are due to an incorrect usage of zlib.
|
|
||||||
Please try to reproduce the problem with a small program and send the
|
|
||||||
corresponding source to us at zlib@gzip.org . Do not send multi-megabyte
|
|
||||||
data files without prior agreement.
|
|
||||||
|
|
||||||
9. Why do I get "undefined reference to gzputc"?
|
|
||||||
|
|
||||||
If "make test" produces something like
|
|
||||||
|
|
||||||
example.o(.text+0x154): undefined reference to `gzputc'
|
|
||||||
|
|
||||||
check that you don't have old files libz.* in /usr/lib, /usr/local/lib or
|
|
||||||
/usr/X11R6/lib. Remove any old versions, then do "make install".
|
|
||||||
|
|
||||||
10. I need a Delphi interface to zlib.
|
|
||||||
|
|
||||||
See the contrib/delphi directory in the zlib distribution.
|
|
||||||
|
|
||||||
11. Can zlib handle .zip archives?
|
|
||||||
|
|
||||||
Not by itself, no. See the directory contrib/minizip in the zlib
|
|
||||||
distribution.
|
|
||||||
|
|
||||||
12. Can zlib handle .Z files?
|
|
||||||
|
|
||||||
No, sorry. You have to spawn an uncompress or gunzip subprocess, or adapt
|
|
||||||
the code of uncompress on your own.
|
|
||||||
|
|
||||||
13. How can I make a Unix shared library?
|
|
||||||
|
|
||||||
By default a shared (and a static) library is built for Unix. So:
|
|
||||||
|
|
||||||
make distclean
|
|
||||||
./configure
|
|
||||||
make
|
|
||||||
|
|
||||||
14. How do I install a shared zlib library on Unix?
|
|
||||||
|
|
||||||
After the above, then:
|
|
||||||
|
|
||||||
make install
|
|
||||||
|
|
||||||
However, many flavors of Unix come with a shared zlib already installed.
|
|
||||||
Before going to the trouble of compiling a shared version of zlib and
|
|
||||||
trying to install it, you may want to check if it's already there! If you
|
|
||||||
can #include <zlib.h>, it's there. The -lz option will probably link to
|
|
||||||
it. You can check the version at the top of zlib.h or with the
|
|
||||||
ZLIB_VERSION symbol defined in zlib.h .
|
|
||||||
|
|
||||||
15. I have a question about OttoPDF.
|
|
||||||
|
|
||||||
We are not the authors of OttoPDF. The real author is on the OttoPDF web
|
|
||||||
site: Joel Hainley, jhainley@myndkryme.com.
|
|
||||||
|
|
||||||
16. Can zlib decode Flate data in an Adobe PDF file?
|
|
||||||
|
|
||||||
Yes. See http://www.pdflib.com/ . To modify PDF forms, see
|
|
||||||
http://sourceforge.net/projects/acroformtool/ .
|
|
||||||
|
|
||||||
17. Why am I getting this "register_frame_info not found" error on Solaris?
|
|
||||||
|
|
||||||
After installing zlib 1.1.4 on Solaris 2.6, running applications using zlib
|
|
||||||
generates an error such as:
|
|
||||||
|
|
||||||
ld.so.1: rpm: fatal: relocation error: file /usr/local/lib/libz.so:
|
|
||||||
symbol __register_frame_info: referenced symbol not found
|
|
||||||
|
|
||||||
The symbol __register_frame_info is not part of zlib, it is generated by
|
|
||||||
the C compiler (cc or gcc). You must recompile applications using zlib
|
|
||||||
which have this problem. This problem is specific to Solaris. See
|
|
||||||
http://www.sunfreeware.com for Solaris versions of zlib and applications
|
|
||||||
using zlib.

18. Why does gzip give an error on a file I make with compress/deflate?
|
|
||||||
|
|
||||||
The compress and deflate functions produce data in the zlib format, which
|
|
||||||
is different and incompatible with the gzip format. The gz* functions in
|
|
||||||
zlib on the other hand use the gzip format. Both the zlib and gzip formats
|
|
||||||
use the same compressed data format internally, but have different headers
|
|
||||||
and trailers around the compressed data.
|
|
||||||
|
|
||||||
19. Ok, so why are there two different formats?
|
|
||||||
|
|
||||||
The gzip format was designed to retain the directory information about a
|
|
||||||
single file, such as the name and last modification date. The zlib format
|
|
||||||
on the other hand was designed for in-memory and communication channel
|
|
||||||
applications, and has a much more compact header and trailer and uses a
|
|
||||||
faster integrity check than gzip.
|
|
||||||
|
|
||||||
20. Well that's nice, but how do I make a gzip file in memory?
|
|
||||||
|
|
||||||
You can request that deflate write the gzip format instead of the zlib
|
|
||||||
format using deflateInit2(). You can also request that inflate decode the
|
|
||||||
gzip format using inflateInit2(). Read zlib.h for more details.
|
|
||||||
|
|
||||||
21. Is zlib thread-safe?
|
|
||||||
|
|
||||||
Yes. However any library routines that zlib uses and any application-
|
|
||||||
provided memory allocation routines must also be thread-safe. zlib's gz*
|
|
||||||
functions use stdio library routines, and most of zlib's functions use the
|
|
||||||
library memory allocation routines by default. zlib's *Init* functions
|
|
||||||
allow for the application to provide custom memory allocation routines.
|
|
||||||
|
|
||||||
Of course, you should only operate on any given zlib or gzip stream from a
|
|
||||||
single thread at a time.
|
|
||||||
|
|
||||||
22. Can I use zlib in my commercial application?
|
|
||||||
|
|
||||||
Yes. Please read the license in zlib.h.
|
|
||||||
|
|
||||||
23. Is zlib under the GNU license?
|
|
||||||
|
|
||||||
No. Please read the license in zlib.h.
|
|
||||||
|
|
||||||
24. The license says that altered source versions must be "plainly marked". So
|
|
||||||
what exactly do I need to do to meet that requirement?
|
|
||||||
|
|
||||||
You need to change the ZLIB_VERSION and ZLIB_VERNUM #defines in zlib.h. In
|
|
||||||
particular, the final version number needs to be changed to "f", and an
|
|
||||||
identification string should be appended to ZLIB_VERSION. Version numbers
|
|
||||||
x.x.x.f are reserved for modifications to zlib by others than the zlib
|
|
||||||
maintainers. For example, if the version of the base zlib you are altering
|
|
||||||
is "1.2.3.4", then in zlib.h you should change ZLIB_VERNUM to 0x123f, and
|
|
||||||
ZLIB_VERSION to something like "1.2.3.f-zachary-mods-v3". You can also
|
|
||||||
update the version strings in deflate.c and inftrees.c.
|
|
||||||
|
|
||||||
For altered source distributions, you should also note the origin and
|
|
||||||
nature of the changes in zlib.h, as well as in ChangeLog and README, along
|
|
||||||
with the dates of the alterations. The origin should include at least your
|
|
||||||
name (or your company's name), and an email address to contact for help or
|
|
||||||
issues with the library.
|
|
||||||
|
|
||||||
Note that distributing a compiled zlib library along with zlib.h and
|
|
||||||
zconf.h is also a source distribution, and so you should change
|
|
||||||
ZLIB_VERSION and ZLIB_VERNUM and note the origin and nature of the changes
|
|
||||||
in zlib.h as you would for a full source distribution.
|
|
||||||
|
|
||||||
25. Will zlib work on a big-endian or little-endian architecture, and can I
|
|
||||||
exchange compressed data between them?
|
|
||||||
|
|
||||||
Yes and yes.
|
|
||||||
|
|
||||||
26. Will zlib work on a 64-bit machine?
|
|
||||||
|
|
||||||
Yes. It has been tested on 64-bit machines, and has no dependence on any
|
|
||||||
data types being limited to 32-bits in length. If you have any
|
|
||||||
difficulties, please provide a complete problem report to zlib@gzip.org
|
|
||||||
|
|
||||||
27. Will zlib decompress data from the PKWare Data Compression Library?
|
|
||||||
|
|
||||||
No. The PKWare DCL uses a completely different compressed data format than
|
|
||||||
does PKZIP and zlib. However, you can look in zlib's contrib/blast
|
|
||||||
directory for a possible solution to your problem.
|
|
||||||
|
|
||||||
28. Can I access data randomly in a compressed stream?
|
|
||||||
|
|
||||||
No, not without some preparation. If when compressing you periodically use
|
|
||||||
Z_FULL_FLUSH, carefully write all the pending data at those points, and
|
|
||||||
keep an index of those locations, then you can start decompression at those
|
|
||||||
points. You have to be careful to not use Z_FULL_FLUSH too often, since it
|
|
||||||
can significantly degrade compression. Alternatively, you can scan a
|
|
||||||
deflate stream once to generate an index, and then use that index for
|
|
||||||
random access. See examples/zran.c .
|
|
||||||
|
|
||||||
29. Does zlib work on MVS, OS/390, CICS, etc.?
|
|
||||||
|
|
||||||
It has in the past, but we have not heard of any recent evidence. There
|
|
||||||
were working ports of zlib 1.1.4 to MVS, but those links no longer work.
|
|
||||||
If you know of recent, successful applications of zlib on these operating
|
|
||||||
systems, please let us know. Thanks.
|
|
||||||
|
|
||||||
30. Is there some simpler, easier to read version of inflate I can look at to
|
|
||||||
understand the deflate format?
|
|
||||||
|
|
||||||
First off, you should read RFC 1951. Second, yes. Look in zlib's
|
|
||||||
contrib/puff directory.
|
|
||||||
|
|
||||||
31. Does zlib infringe on any patents?
|
|
||||||
|
|
||||||
As far as we know, no. In fact, that was originally the whole point behind
|
|
||||||
zlib. Look here for some more information:
|
|
||||||
|
|
||||||
http://www.gzip.org/#faq11
|
|
||||||
|
|
||||||
32. Can zlib work with greater than 4 GB of data?
|
|
||||||
|
|
||||||
Yes. inflate() and deflate() will process any amount of data correctly.
|
|
||||||
Each call of inflate() or deflate() is limited to input and output chunks
|
|
||||||
of the maximum value that can be stored in the compiler's "unsigned int"
|
|
||||||
type, but there is no limit to the number of chunks. Note however that the
|
|
||||||
strm.total_in and strm_total_out counters may be limited to 4 GB. These
|
|
||||||
counters are provided as a convenience and are not used internally by
|
|
||||||
inflate() or deflate(). The application can easily set up its own counters
|
|
||||||
updated after each call of inflate() or deflate() to count beyond 4 GB.
|
|
||||||
compress() and uncompress() may be limited to 4 GB, since they operate in a
|
|
||||||
single call. gzseek() and gztell() may be limited to 4 GB depending on how
|
|
||||||
zlib is compiled. See the zlibCompileFlags() function in zlib.h.
|
|
||||||
|
|
||||||
The word "may" appears several times above since there is a 4 GB limit only
|
|
||||||
if the compiler's "long" type is 32 bits. If the compiler's "long" type is
|
|
||||||
64 bits, then the limit is 16 exabytes.
|
|
||||||
|
|
||||||
33. Does zlib have any security vulnerabilities?
|
|
||||||
|
|
||||||
The only one that we are aware of is potentially in gzprintf(). If zlib is
|
|
||||||
compiled to use sprintf() or vsprintf(), then there is no protection
|
|
||||||
against a buffer overflow of an 8K string space (or other value as set by
|
|
||||||
gzbuffer()), other than the caller of gzprintf() assuring that the output
|
|
||||||
will not exceed 8K. On the other hand, if zlib is compiled to use
|
|
||||||
snprintf() or vsnprintf(), which should normally be the case, then there is
|
|
||||||
no vulnerability. The ./configure script will display warnings if an
|
|
||||||
insecure variation of sprintf() will be used by gzprintf(). Also the
|
|
||||||
zlibCompileFlags() function will return information on what variant of
|
|
||||||
sprintf() is used by gzprintf().
|
|
||||||
|
|
||||||
If you don't have snprintf() or vsnprintf() and would like one, you can
|
|
||||||
find a portable implementation here:
|
|
||||||
|
|
||||||
http://www.ijs.si/software/snprintf/
|
|
||||||
|
|
||||||
Note that you should be using the most recent version of zlib. Versions
|
|
||||||
1.1.3 and before were subject to a double-free vulnerability, and versions
|
|
||||||
1.2.1 and 1.2.2 were subject to an access exception when decompressing
|
|
||||||
invalid compressed data.
|
|
||||||
|
|
||||||
34. Is there a Java version of zlib?
|
|
||||||
|
|
||||||
Probably what you want is to use zlib in Java. zlib is already included
|
|
||||||
as part of the Java SDK in the java.util.zip package. If you really want
|
|
||||||
a version of zlib written in the Java language, look on the zlib home
|
|
||||||
page for links: http://zlib.net/ .
|
|
||||||
|
|
||||||
35. I get this or that compiler or source-code scanner warning when I crank it
|
|
||||||
up to maximally-pedantic. Can't you guys write proper code?
|
|
||||||
|
|
||||||
Many years ago, we gave up attempting to avoid warnings on every compiler
|
|
||||||
in the universe. It just got to be a waste of time, and some compilers
|
|
||||||
were downright silly as well as contradicted each other. So now, we simply
|
|
||||||
make sure that the code always works.
|
|
||||||
|
|
||||||
36. Valgrind (or some similar memory access checker) says that deflate is
|
|
||||||
performing a conditional jump that depends on an uninitialized value.
|
|
||||||
Isn't that a bug?
|
|
||||||
|
|
||||||
No. That is intentional for performance reasons, and the output of deflate
|
|
||||||
is not affected. This only started showing up recently since zlib 1.2.x
|
|
||||||
uses malloc() by default for allocations, whereas earlier versions used
|
|
||||||
calloc(), which zeros out the allocated memory. Even though the code was
|
|
||||||
correct, versions 1.2.4 and later was changed to not stimulate these
|
|
||||||
checkers.
|
|
||||||
|
|
||||||
37. Will zlib read the (insert any ancient or arcane format here) compressed
|
|
||||||
data format?
|
|
||||||
|
|
||||||
Probably not. Look in the comp.compression FAQ for pointers to various
|
|
||||||
formats and associated software.
|
|
||||||
|
|
||||||
38. How can I encrypt/decrypt zip files with zlib?
|
|
||||||
|
|
||||||
zlib doesn't support encryption. The original PKZIP encryption is very
|
|
||||||
weak and can be broken with freely available programs. To get strong
|
|
||||||
encryption, use GnuPG, http://www.gnupg.org/ , which already includes zlib
|
|
||||||
compression. For PKZIP compatible "encryption", look at
|
|
||||||
http://www.info-zip.org/
|
|
||||||
|
|
||||||
39. What's the difference between the "gzip" and "deflate" HTTP 1.1 encodings?
|
|
||||||
|
|
||||||
"gzip" is the gzip format, and "deflate" is the zlib format. They should
|
|
||||||
probably have called the second one "zlib" instead to avoid confusion with
|
|
||||||
the raw deflate compressed data format. While the HTTP 1.1 RFC 2616
|
|
||||||
correctly points to the zlib specification in RFC 1950 for the "deflate"
|
|
||||||
transfer encoding, there have been reports of servers and browsers that
|
|
||||||
incorrectly produce or expect raw deflate data per the deflate
|
|
||||||
specification in RFC 1951, most notably Microsoft. So even though the
|
|
||||||
"deflate" transfer encoding using the zlib format would be the more
|
|
||||||
efficient approach (and in fact exactly what the zlib format was designed
|
|
||||||
for), using the "gzip" transfer encoding is probably more reliable due to
|
|
||||||
an unfortunate choice of name on the part of the HTTP 1.1 authors.
|
|
||||||
|
|
||||||
Bottom line: use the gzip format for HTTP 1.1 encoding.
|
|
||||||
|
|
||||||
40. Does zlib support the new "Deflate64" format introduced by PKWare?
|
|
||||||
|
|
||||||
No. PKWare has apparently decided to keep that format proprietary, since
|
|
||||||
they have not documented it as they have previous compression formats. In
|
|
||||||
any case, the compression improvements are so modest compared to other more
|
|
||||||
modern approaches, that it's not worth the effort to implement.
|
|
||||||
|
|
||||||
41. I'm having a problem with the zip functions in zlib, can you help?
|
|
||||||
|
|
||||||
There are no zip functions in zlib. You are probably using minizip by
|
|
||||||
Giles Vollant, which is found in the contrib directory of zlib. It is not
|
|
||||||
part of zlib. In fact none of the stuff in contrib is part of zlib. The
|
|
||||||
files in there are not supported by the zlib authors. You need to contact
|
|
||||||
the authors of the respective contribution for help.
|
|
||||||
|
|
||||||
42. The match.asm code in contrib is under the GNU General Public License.
|
|
||||||
Since it's part of zlib, doesn't that mean that all of zlib falls under the
|
|
||||||
GNU GPL?
|
|
||||||
|
|
||||||
No. The files in contrib are not part of zlib. They were contributed by
|
|
||||||
other authors and are provided as a convenience to the user within the zlib
|
|
||||||
distribution. Each item in contrib has its own license.
|
|
||||||
|
|
||||||
43. Is zlib subject to export controls? What is its ECCN?
|
|
||||||
|
|
||||||
zlib is not subject to export controls, and so is classified as EAR99.
|
|
||||||
|
|
||||||
44. Can you please sign these lengthy legal documents and fax them back to us
|
|
||||||
so that we can use your software in our product?
|
|
||||||
|
|
||||||
No. Go away. Shoo.

ZLIB DATA COMPRESSION LIBRARY
|
|
||||||
|
|
||||||
zlib 1.3.1 is a general purpose data compression library. All the code is
|
|
||||||
thread safe. The data format used by the zlib library is described by RFCs
|
|
||||||
(Request for Comments) 1950 to 1952 in the files
|
|
||||||
http://tools.ietf.org/html/rfc1950 (zlib format), rfc1951 (deflate format) and
|
|
||||||
rfc1952 (gzip format).
|
|
||||||
|
|
||||||
All functions of the compression library are documented in the file zlib.h
|
|
||||||
(volunteer to write man pages welcome, contact zlib@gzip.org). A usage example
|
|
||||||
of the library is given in the file test/example.c which also tests that
|
|
||||||
the library is working correctly. Another example is given in the file
|
|
||||||
test/minigzip.c. The compression library itself is composed of all source
|
|
||||||
files in the root directory.
|
|
||||||
|
|
||||||
To compile all files and run the test program, follow the instructions given at
|
|
||||||
the top of Makefile.in. In short "./configure; make test", and if that goes
|
|
||||||
well, "make install" should work for most flavors of Unix. For Windows, use
|
|
||||||
one of the special makefiles in win32/ or contrib/vstudio/ . For VMS, use
|
|
||||||
make_vms.com.
|
|
||||||
|
|
||||||
Questions about zlib should be sent to <zlib@gzip.org>, or to Gilles Vollant
|
|
||||||
<info@winimage.com> for the Windows DLL version. The zlib home page is
|
|
||||||
http://zlib.net/ . Before reporting a problem, please check this site to
|
|
||||||
verify that you have the latest version of zlib; otherwise get the latest
|
|
||||||
version and check whether the problem still exists or not.
|
|
||||||
|
|
||||||
PLEASE read the zlib FAQ http://zlib.net/zlib_faq.html before asking for help.
|
|
||||||
|
|
||||||
Mark Nelson <markn@ieee.org> wrote an article about zlib for the Jan. 1997
|
|
||||||
issue of Dr. Dobb's Journal; a copy of the article is available at
|
|
||||||
https://marknelson.us/posts/1997/01/01/zlib-engine.html .
|
|
||||||
|
|
||||||
The changes made in version 1.3.1 are documented in the file ChangeLog.
|
|
||||||
|
|
||||||
Unsupported third party contributions are provided in directory contrib/ .
|
|
||||||
|
|
||||||
zlib is available in Java using the java.util.zip package. Follow the API
|
|
||||||
Documentation link at: https://docs.oracle.com/search/?q=java.util.zip .
|
|
||||||
|
|
||||||
A Perl interface to zlib and bzip2 written by Paul Marquess <pmqs@cpan.org>
|
|
||||||
can be found at https://github.com/pmqs/IO-Compress .
|
|
||||||
|
|
||||||
A Python interface to zlib written by A.M. Kuchling <amk@amk.ca> is
|
|
||||||
available in Python 1.5 and later versions, see
|
|
||||||
http://docs.python.org/library/zlib.html .
|
|
||||||
|
|
||||||
zlib is built into tcl: http://wiki.tcl.tk/4610 .
|
|
||||||
|
|
||||||
An experimental package to read and write files in .zip format, written on top
|
|
||||||
of zlib by Gilles Vollant <info@winimage.com>, is available in the
|
|
||||||
contrib/minizip directory of zlib.
|
|
||||||
|
|
||||||
|
|
||||||
Notes for some targets:
|
|
||||||
|
|
||||||
- For Windows DLL versions, please see win32/DLL_FAQ.txt
|
|
||||||
|
|
||||||
- For 64-bit Irix, deflate.c must be compiled without any optimization. With
|
|
||||||
-O, one libpng test fails. The test works in 32 bit mode (with the -n32
|
|
||||||
compiler flag). The compiler bug has been reported to SGI.
|
|
||||||
|
|
||||||
- zlib doesn't work with gcc 2.6.3 on a DEC 3000/300LX under OSF/1 2.1 it works
|
|
||||||
when compiled with cc.
|
|
||||||
|
|
||||||
- On Digital Unix 4.0D (formerly OSF/1) on AlphaServer, the cc option -std1 is
|
|
||||||
necessary to get gzprintf working correctly. This is done by configure.
|
|
||||||
|
|
||||||
- zlib doesn't work on HP-UX 9.05 with some versions of /bin/cc. It works with
|
|
||||||
other compilers. Use "make test" to check your compiler.
|
|
||||||
|
|
||||||
- gzdopen is not supported on RISCOS or BEOS.
|
|
||||||
|
|
||||||

||||||
The deflate format used by zlib was defined by Phil Katz. The deflate and
|
|
||||||
zlib specifications were written by L. Peter Deutsch. Thanks to all the
|
|
||||||
people who reported problems and suggested various improvements in zlib; they
|
|

are too numerous to cite here.

ZLib for Ada thick binding (ZLib.Ada)
|
|
||||||
Release 1.3
|
|
||||||
|
|
||||||
ZLib.Ada is a thick binding interface to the popular ZLib data
|
|
||||||
compression library, available at http://www.gzip.org/zlib/.
|
|
||||||
It provides Ada-style access to the ZLib C library.
|
|
||||||
|
|
||||||
|
|
||||||
Here are the main changes since ZLib.Ada 1.2:
|
|
||||||
|
|
||||||
- Attention: ZLib.Read generic routine have a initialization requirement
|
|
||||||
for Read_Last parameter now. It is a bit incompatible with previous version,
|
|
||||||
but extends functionality, we could use new parameters Allow_Read_Some and
|
|
||||||
Flush now.
|
|
||||||
|
|
||||||
- Added Is_Open routines to ZLib and ZLib.Streams packages.
|
|
||||||
|
|
||||||
- Add pragma Assert to check Stream_Element is 8 bit.
|
|
||||||
|
|
||||||
- Fix extraction to buffer with exact known decompressed size. Error reported by
|
|
||||||
Steve Sangwine.
|
|
||||||
|
|
||||||
- Fix definition of ULong (changed to unsigned_long), fix regression on 64 bits
|
|
||||||
computers. Patch provided by Pascal Obry.
|
|
||||||
|
|
||||||
- Add Status_Error exception definition.
|
|
||||||
|
|
||||||
- Add pragma Assertion that Ada.Streams.Stream_Element size is 8 bit.
|
|
||||||
|
|
||||||
|
|
||||||
How to build ZLib.Ada under GNAT
|
|
||||||
|
|
||||||
You should have the ZLib library already build on your computer, before
|
|
||||||
building ZLib.Ada. Make the directory of ZLib.Ada sources current and
|
|
||||||
issue the command:
|
|
||||||
|
|
||||||
gnatmake test -largs -L<directory where libz.a is> -lz
|
|
||||||
|
|
||||||
Or use the GNAT project file build for GNAT 3.15 or later:
|
|
||||||
|
|
||||||
gnatmake -Pzlib.gpr -L<directory where libz.a is>
|
|
||||||
|
|
||||||
|
|
||||||
How to build ZLib.Ada under Aonix ObjectAda for Win32 7.2.2
|
|
||||||
|
|
||||||
1. Make a project with all *.ads and *.adb files from the distribution.
|
|
||||||
2. Build the libz.a library from the ZLib C sources.
|
|
||||||
3. Rename libz.a to z.lib.
|
|
||||||
4. Add the library z.lib to the project.
|
|
||||||
5. Add the libc.lib library from the ObjectAda distribution to the project.
|
|
||||||
6. Build the executable using test.adb as a main procedure.
|
|
||||||
|
|
||||||
|
|
||||||
How to use ZLib.Ada
|
|
||||||
|
|
||||||
The source files test.adb and read.adb are small demo programs that show
|
|
||||||
the main functionality of ZLib.Ada.
|
|
||||||
|
|
||||||
The routines from the package specifications are commented.

|
|
||||||
* 00 04 82 24 25 8f 80 7f
|
|

*
|
|
||||||
* - First byte is 0 if literals are uncoded or 1 if they are coded. Second
|
|
||||||
* byte is 4, 5, or 6 for the number of extra bits in the distance code.
|
|
||||||
* This is the base-2 logarithm of the dictionary size minus six.
|
|
||||||
*
|
|
||||||
* - Compressed data is a combination of literals and length/distance pairs
|
|
||||||
* terminated by an end code. Literals are either Huffman coded or
|
|
||||||
* uncoded bytes. A length/distance pair is a coded length followed by a
|
|
||||||
* coded distance to represent a string that occurs earlier in the
|
|
||||||
* uncompressed data that occurs again at the current location.
|
|
||||||
*
|
|
||||||
* - A bit preceding a literal or length/distance pair indicates which comes
|
|
||||||
* next, 0 for literals, 1 for length/distance.
|
|
||||||
*
|
|
||||||
* - If literals are uncoded, then the next eight bits are the literal, in the
|
|
||||||
* normal bit order in the stream, i.e. no bit-reversal is needed. Similarly,
|
|
||||||
* no bit reversal is needed for either the length extra bits or the distance
|
|
||||||
* extra bits.
|
|
||||||
*
|
|
||||||
* - Literal bytes are simply written to the output. A length/distance pair is
|
|
||||||
* an instruction to copy previously uncompressed bytes to the output. The
|
|
||||||
* copy is from distance bytes back in the output stream, copying for length
|
|
||||||
* bytes.
|
|
||||||
*
|
|
||||||
* - Distances pointing before the beginning of the output data are not
|
|
||||||
* permitted.
|
|
||||||
*
|
|
||||||
* - Overlapped copies, where the length is greater than the distance, are
|
|
||||||
* allowed and common. For example, a distance of one and a length of 518
|
|
||||||
* simply copies the last byte 518 times. A distance of four and a length of
|
|
||||||
* twelve copies the last four bytes three times. A simple forward copy
|
|
||||||
* ignoring whether the length is greater than the distance or not implements
|
|
||||||
* this correctly.

TCompressionStream is write-only and strictly sequential. Reading from the

stream will raise an exception. Using Seek to move the stream pointer
|
|
||||||
will raise an exception.
|
|

Output data is cached internally, written to the output stream only when
|
|
||||||
the internal output buffer is full. All pending output data is flushed
|
|
||||||
when the stream is destroyed.
|
|
||||||
|
|
||||||
The Position property returns the number of uncompressed bytes of
|
|
||||||
data that have been written to the stream so far.
|

|
|
||||||
CompressionRate returns the on-the-fly percentage by which the original
|
|
||||||
data has been compressed: (1 - (CompressedBytes / UncompressedBytes)) * 100
|
|
||||||
If raw data size = 100 and compressed data size = 25, the CompressionRate
|
|
||||||
is 75%
|
|
||||||
|
|
||||||
The OnProgress event is called each time the output buffer is filled and
|
|
||||||
written to the output stream. This is useful for updating a progress
|
|
||||||
indicator when you are writing a large chunk of data to the compression
|
|
||||||
stream in a single call.}

|
|

|
|
||||||
Compressed data comes from a separate source stream. TDecompressionStream
|
|
||||||
is read-only and unidirectional; you can seek forward in the stream, but not
|
|
||||||
backwards. The special case of setting the stream position to zero is
|
|
||||||
allowed. Seeking forward decompresses data until the requested position in
|
|
||||||
the uncompressed data has been reached. Seeking backwards, seeking relative
|
|
||||||
to the end of the stream, requesting the size of the stream, and writing to
|
|
||||||
the stream will raise an exception.
|
|
||||||
|
|
||||||
The Position property returns the number of bytes of uncompressed data that
|
|
||||||
have been read from the stream so far.
|
|
||||||
|
|
||||||
The OnProgress event is called each time the internal input buffer of
|
|
||||||
compressed data is exhausted and the next block is read from the input stream.
|
|
||||||
This is useful for updating a progress indicator when you are reading a

large chunk of data from the decompression stream in a single call.}

Overview
|
|
||||||
========
|
|
||||||
|
|
||||||
This directory contains an update to the ZLib interface unit,
|
|
||||||
distributed by Borland as a Delphi supplemental component.
|
|
||||||
|
|
||||||
The original ZLib unit is Copyright (c) 1997,99 Borland Corp.,
|
|
||||||
and is based on zlib version 1.0.4. There are a series of bugs
|
|
||||||
and security problems associated with that old zlib version, and
|
|
||||||
we recommend the users to update their ZLib unit.
|
|
||||||
|
|
||||||
|
|
||||||
Summary of modifications
|
|
||||||
========================
|
|
||||||
|
|
||||||
- Improved makefile, adapted to zlib version 1.2.1.
|
|
||||||
|
|
||||||
- Some field types from TZStreamRec are changed from Integer to
|
|
||||||
Longint, for consistency with the zlib.h header, and for 64-bit
|
|
||||||
readiness.
|
|
||||||
|
|
||||||
- The zlib_version constant is updated.
|
|
||||||
|
|
||||||
- The new Z_RLE strategy has its corresponding symbolic constant.
|
|
||||||
|
|
||||||
- The allocation and deallocation functions and function types
|
|
||||||
(TAlloc, TFree, zlibAllocMem and zlibFreeMem) are now cdecl,
|
|
||||||
and _malloc and _free are added as C RTL stubs. As a result,
|
|
||||||
the original C sources of zlib can be compiled out of the box,
|
|
||||||
and linked to the ZLib unit.
|
|
||||||
|
|
||||||
|
|
||||||
Suggestions for improvements
|
|
||||||
============================
|
|
||||||
|
|
||||||
Currently, the ZLib unit provides only a limited wrapper around
|
|
||||||
the zlib library, and much of the original zlib functionality is
|
|
||||||
missing. Handling compressed file formats like ZIP/GZIP or PNG
|
|
||||||
cannot be implemented without having this functionality.
|
|
||||||
Applications that handle these formats are either using their own,
|
|
||||||
duplicated code, or not using the ZLib unit at all.
|
|
||||||
|
|
||||||
Here are a few suggestions:
|
|
||||||
|
|
||||||
- Checksum class wrappers around adler32() and crc32(), similar
|
|
||||||
to the Java classes that implement the java.util.zip.Checksum
|
|
||||||
interface.
|
|
||||||
|
|
||||||
- The ability to read and write raw deflate streams, without the
|
|
||||||
zlib stream header and trailer. Raw deflate streams are used
|
|
||||||
in the ZIP file format.
|
|
||||||
|
|
||||||
- The ability to read and write gzip streams, used in the GZIP
|
|
||||||
file format, and normally produced by the gzip program.
|
|
||||||
|
|
||||||
- The ability to select a different compression strategy, useful
|
|
||||||
to PNG and MNG image compression, and to multimedia compression
|
|
||||||
in general. Besides the compression level
|
|
||||||
|
|
||||||
TCompressionLevel = (clNone, clFastest, clDefault, clMax);
|
|
||||||
|
|
||||||
which, in fact, could have used the 'z' prefix and avoided
|
|
||||||
TColor-like symbols
|
|
||||||
|
|
||||||
TCompressionLevel = (zcNone, zcFastest, zcDefault, zcMax);
|
|
||||||
|
|
||||||
there could be a compression strategy
|
|
||||||
|
|
||||||
TCompressionStrategy = (zsDefault, zsFiltered, zsHuffmanOnly, zsRle);
|
|
||||||
|
|
||||||
- ZIP and GZIP stream handling via TStreams.

This directory contains a .Net wrapper class library for the ZLib1.dll
|

|
|
||||||
The wrapper includes support for inflating/deflating memory buffers,
|
|
||||||
.Net streaming wrappers for the gz streams part of zlib, and wrappers
|
|
||||||
for the checksum parts of zlib. See DotZLib/UnitTests.cs for examples.

|
|
||||||
Unit tests:
|
|
||||||
-----------
|
|
||||||
The file DotZLib/UnitTests.cs contains unit tests for use with NUnit 2.1 or higher.
|
|
||||||
To include unit tests in the build, define nunit before building.
|
|
||||||
|
|
||||||
|
|
||||||
Build instructions:
|
|
||||||
-------------------
|
|
||||||
|
|
||||||
1. Using Visual Studio.Net 2003:
|
|
||||||
Open DotZLib.sln in VS.Net and build from there. Output file (DotZLib.dll)
|
|
||||||
will be found ./DotZLib/bin/release or ./DotZLib/bin/debug, depending on
|
|
||||||
you are building the release or debug version of the library. Check
|
|
||||||
DotZLib/UnitTests.cs for instructions on how to include unit tests in the
|
|
||||||
build.
|
|
||||||
|
|
||||||
2. Using NAnt:
|
|
||||||
Open a command prompt with access to the build environment and run nant
|
|
||||||
in the same directory as the DotZLib.build file.
|
|
||||||
You can define 2 properties on the nant command-line to control the build:
|
|
||||||
debug={true|false} to toggle between release/debug builds (default=true).
|
|
||||||
nunit={true|false} to include or exclude unit tests (default=true).
|
|
||||||
Also the target clean will remove binaries.
|
|
||||||
Output file (DotZLib.dll) will be found in either ./DotZLib/bin/release
|
|
||||||
or ./DotZLib/bin/debug, depending on whether you are building the release
|
|
||||||
or debug version of the library.
|
|
||||||
|
|
||||||
Examples:
|
|
||||||
nant -D:debug=false -D:nunit=false
|
|
||||||
will build a release mode version of the library without unit tests.
|
|
||||||
nant
|
|
||||||
will build a debug version of the library with unit tests
|
|
||||||
nant clean
|
|
||||||
will remove all previously built files.

returns, strm will also provide an error message.
|
|

|

in() and out() are the call-back input and output functions. When

inflateBack() needs more input, it calls in(). When inflateBack() has

filled the window with output, or when it completes with data in the

window, it calls out() to write out the data. The application must not

change the provided input until in() is called again or inflateBack()
|

returns. The application must not change the window/output buffer until
|

inflateBack() returns.
|
|

|

in() and out() are called with a descriptor parameter provided in the

inflateBack() call. This parameter can be a structure that provides the

information required to do the read or write, as well as accumulated

information on the input and output such as totals and check values.
|

in() should return zero on failure. out() should return non-zero on
|

failure. If either in() or out() fails, than inflateBack() returns a
|
|

Z_BUF_ERROR. strm->next_in can be checked for Z_NULL to see whether it
|
|

was in() or out() that caused in the error. Otherwise, inflateBack()
|

returns Z_STREAM_END on success, Z_DATA_ERROR for an deflate format
|

error, or Z_MEM_ERROR if it could not allocate memory for the state.

inflateBack() can also return Z_STREAM_ERROR if the input parameters

Process a set of code lengths to create a canonical Huffman code. The
|
|
||||||
code lengths are lens[0..codes-1]. Each length corresponds to the
|
|
||||||
symbols 0..codes-1. The Huffman code is generated by first sorting the
|
|
||||||
symbols by length from short to long, and retaining the symbol order
|
|
||||||
for codes with equal lengths. Then the code starts with all zero bits
|
|
||||||
for the first code of the shortest length, and the codes are integer
|
|
||||||
increments for the same length, and zeros are appended as the length
|
|
||||||
increases. For the deflate format, these bits are stored backwards
|
|
||||||
from their more natural integer increment ordering, and so when the
|
|
||||||
decoding tables are built in the large loop below, the integer codes
|
|
||||||
are incremented backwards.
|
|
||||||
|
|
||||||
This routine assumes, but does not check, that all of the entries in
|
|
||||||
lens[] are in the range 0..MAXBITS. The caller must assure this.
|
|
||||||
1..MAXBITS is interpreted as that code length. zero means that that
|
|
||||||
symbol does not occur in this code.
|
|
||||||
|
|
||||||
The codes are sorted by computing a count of codes for each length,
|
|
||||||
creating from that a table of starting indices for each length in the
|
|
||||||
sorted table, and then entering the symbols in order in the sorted
|
|
||||||
table. The sorted table is work[], with that space being provided by
|
|
||||||
the caller.
|
|
||||||
|
|
||||||
The length counts are used for other purposes as well, i.e. finding
|
|
||||||
the minimum and maximum length codes, determining if there are any
|
|
||||||
codes at all, checking for a valid set of lengths, and looking ahead
|
|
||||||
at length counts to determine sub-table sizes when building the

decoding tables.

Create and fill in decoding tables. In this loop, the table being

filled is at next and has curr index bits. The code being used is huff
|
|

with length len. That code is converted to an index by dropping drop
|
|

bits off of the bottom. For codes where len is less than drop + curr,
|
|
||||||
those top drop + curr - len bits are incremented through all values to
|
|

fill the table with replicated entries.
|
|
||||||
|

root is the number of index bits for the root table. When len exceeds
|
|

root, sub-tables are created pointed to by the root entry with an index
|
|
||||||
of the low root bits of huff. This is saved in low to check for when a
|
|

new sub-table should be started. drop is zero when the root table is
|
|
||||||
being filled, and drop is root when sub-tables are being filled.
|
|
||||||
|
|
||||||
When a new sub-table is needed, it is necessary to look ahead in the
|
|
||||||
code lengths to determine what size sub-table is needed. The length
|
|
||||||
counts are used for this, and so count[] is decremented as codes are
|
|
||||||
entered in the tables.
|
|
||||||
|
|

used keeps track of how many table entries have been allocated from the
|
|

provided *table space. It is checked for LENS and DIST tables against
|
|
||||||
the constants ENOUGH_LENS and ENOUGH_DISTS to guard against changes in

the initial root table size constants. See the comments in inftree9.h

for more information.
|

|
|
||||||
sym increments through all symbols, and the loop terminates when
|
|
||||||
all codes of length max, i.e. all codes, have been processed. This
|

routine permits incomplete codes, so another loop after this one fills
|
|
||||||
in the rest of the decoding tables with invalid code markers.

These classes provide a C++ stream interface to the zlib library. It allows you
|
|
||||||
to do things like:
|
|
||||||
|
|
||||||
gzofstream outf("blah.gz");
|
|
||||||
outf << "These go into the gzip file " << 123 << endl;
|
|
||||||
|
|
||||||
It does this by deriving a specialized stream buffer for gzipped files, which is
|
|
||||||
the way Stroustrup would have done it. :->
|
|
||||||
|
|
||||||
The gzifstream and gzofstream classes were originally written by Kevin Ruland
|
|
||||||
and made available in the zlib contrib/iostream directory. The older version still
|
|
||||||
compiles under gcc 2.xx, but not under gcc 3.xx, which sparked the development of
|
|
||||||
this version.
|
|
||||||
|
|
||||||
The new classes are as standard-compliant as possible, closely following the
|
|
||||||
approach of the standard library's fstream classes. It compiles under gcc versions
|
|
||||||
3.2 and 3.3, but not under gcc 2.xx. This is mainly due to changes in the standard
|
|
||||||
library naming scheme. The new version of gzifstream/gzofstream/gzfilebuf differs
|
|
||||||
from the previous one in the following respects:
|
|
||||||
- added showmanyc
|
|
||||||
- added setbuf, with support for unbuffered output via setbuf(0,0)
|
|
||||||
- a few bug fixes of stream behavior
|
|
||||||
- gzipped output file opened with default compression level instead of maximum level
|
|
||||||
- setcompressionlevel()/strategy() members replaced by single setcompression()
|
|
||||||
|
|
||||||
The code is provided "as is", with the permission to use, copy, modify, distribute
|
|
||||||
and sell it for any purpose without fee.

Possible upgrades to gzfilebuf:
|
|
||||||
|
|
||||||
- The ability to do putback (e.g. putbackfail)
|
|
||||||
|
|
||||||
- The ability to seek (zlib supports this, but could be slow/tricky)
|
|
||||||
|
|
||||||
- Simultaneous read/write access (does it make sense?)
|
|
||||||
|
|
||||||
- Support for ios_base::ate open mode
|
|
||||||
|
|
||||||
- Locale support?
|
|
||||||
|
|
||||||
- Check public interface to see which calls give problems
|
|
||||||
(due to dependence on library internals)
|
|
||||||
|
|
||||||
- Override operator<<(ostream&, gzfilebuf*) to allow direct copying
|
|
||||||
of stream buffer to stream ( i.e. os << is.rdbuf(); )

MiniZip - Copyright (c) 1998-2010 - by Gilles Vollant - version 1.1 64 bits from Mathias Svensson
|
|
||||||
|
|
||||||
Introduction
|
|
||||||
---------------------
|
|
||||||
MiniZip 1.1 is built from MiniZip 1.0 by Gilles Vollant ( http://www.winimage.com/zLibDll/minizip.html )
|
|
||||||
|
|
||||||
When adding ZIP64 support into minizip it would result into risk of breaking compatibility with minizip 1.0.
|
|
||||||
All possible work was done for compatibility.
|
|
||||||
|
|
||||||
|
|
||||||
Background
|
|
||||||
---------------------
|
|
||||||
When adding ZIP64 support Mathias Svensson found that Even Rouault have added ZIP64
|
|
||||||
support for unzip.c into minizip for a open source project called gdal ( http://www.gdal.org/ )
|
|
||||||
|
|
||||||
That was used as a starting point. And after that ZIP64 support was added to zip.c
|
|
||||||
some refactoring and code cleanup was also done.
|
|
||||||
|
|
||||||
|
|
||||||
Changed from MiniZip 1.0 to MiniZip 1.1
|
|
||||||
---------------------------------------
|
|
||||||
* Added ZIP64 support for unzip ( by Even Rouault )
|
|
||||||
* Added ZIP64 support for zip ( by Mathias Svensson )
|
|
||||||
* Reverted some changed that Even Rouault did.
|
|
||||||
* Bunch of patches received from Gulles Vollant that he received for MiniZip from various users.
|
|
||||||
* Added unzip patch for BZIP Compression method (patch create by Daniel Borca)
|
|
||||||
* Added BZIP Compress method for zip
|
|
||||||
* Did some refactoring and code cleanup
|

||||||
This code is a modified version of crypting code in Infozip distribution
|
|
||||||
|
|
||||||
The encryption/decryption parts of this source code (as opposed to the
|
|
||||||
non-echoing password parts) were originally written in Europe. The
|
|
||||||
whole source package can be freely distributed, including from the USA.
|
|
||||||
(Prior to January 2000, re-export from the US was a violation of US law.)
|
|
||||||
|
|
||||||
This encryption code is a direct transcription of the algorithm from
|
|
||||||
Roger Schlafly, described by Phil Katz in the file appnote.txt. This
|
|
||||||
file (appnote.txt) is distributed with the PKZIP program (even in the
|
|
||||||
version without encryption capabilities).
|
|
||||||
|
|
||||||
If you don't need crypting in your application, just define symbols
|
|
||||||
NOCRYPT and NOUNCRYPT.
|
|
||||||
|
|
||||||
This code support the "Traditional PKWARE Encryption".
|
|
||||||
|
|
||||||
The new AES encryption added on Zip format by Winzip (see the page
|
|
||||||
http://www.winzip.com/aes_info.htm ) and PKWare PKZip 5.x Strong

Encryption is not supported.

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)

.SH NAME
|
|
||||||
miniunzip - uncompress and examine ZIP archives
|
|
||||||
.SH SYNOPSIS
|
|
||||||
.B miniunzip
|
|
||||||
.RI [ -exvlo ]
|
|
||||||
zipfile [ files_to_extract ] [-d tempdir]
|
|
||||||
.SH DESCRIPTION
|
|
||||||
.B minizip
|
|
||||||
is a simple tool which allows the extraction of compressed file
|
|
||||||
archives in the ZIP format used by the MS-DOS utility PKZIP. It was
|
|
||||||
written as a demonstration of the
|
|
||||||
.IR zlib (3)
|
|
||||||
library and therefore lack many of the features of the
|
|
||||||
.IR unzip (1)
|
|
||||||
program.
|
|
||||||
.SH OPTIONS
|
|
||||||
A number of options are supported. With the exception of
|
|
||||||
.BI \-d\ tempdir
|
|
||||||
these must be supplied before any
|
|
||||||
other arguments and are:
|
|
||||||
.TP
|
|
||||||
.BI \-l\ ,\ \-\-v
|
|
||||||
List the files in the archive without extracting them.
|
|
||||||
.TP
|
|
||||||
.B \-o
|
|
||||||
Overwrite files without prompting for confirmation.
|
|
||||||
.TP
|
|
||||||
.B \-x
|
|
||||||
Extract files (default).
|
|
||||||
.PP
|
|
||||||
The
|
|
||||||
.I zipfile
|
|
||||||
argument is the name of the archive to process. The next argument can be used
|
|
||||||
to specify a single file to extract from the archive.
|
|
||||||
|
|
||||||
Lastly, the following option can be specified at the end of the command-line:
|
|
||||||
.TP
|
|
||||||
.BI \-d\ tempdir
|
|
||||||
Extract the archive in the directory
|
|
||||||
.I tempdir
|
|
||||||
rather than the current directory.
|
|
||||||

This program was written by Gilles Vollant. This manual page was

was added by Dirk Eddelbuettel <edd@debian.org>.

|
|
||||||
.B minizip
|

|
|
||||||
.SH DESCRIPTION
|
|
||||||
.B minizip
|
|
||||||
is a simple tool which allows the creation of compressed file archives
|
|
||||||
in the ZIP format used by the MS-DOS utility PKZIP. It was written as

|
|
||||||
.IR zip (1)
|
|
||||||
program.
|
|
||||||
.SH OPTIONS
|
|
||||||
The first argument supplied is the name of the ZIP archive to create or
|
|
||||||
.RI -o
|
|
||||||
in which case it is ignored and the second argument treated as the
|
|
||||||
name of the ZIP file. If the ZIP file already exists it will be
|
|
||||||
overwritten.
|
|
||||||
.PP
|
|
||||||
Subsequent arguments specify a list of files to place in the ZIP
|
|
||||||
archive. If none are specified then an empty archive will be created.

Compatibility notes
|
|
||||||
===================
|
|
||||||
|
|
||||||
- Although the name "zlib" would have been more normal for the
|
|
||||||
zlibpas unit, this name is already taken by Borland's ZLib unit.
|
|
||||||
This is somehow unfortunate, because that unit is not a genuine
|
|
||||||
interface to the full-fledged zlib functionality, but a suite of
|
|
||||||
class wrappers around zlib streams. Other essential features,
|
|
||||||
such as checksums, are missing.
|
|
||||||
It would have been more appropriate for that unit to have a name
|
|
||||||
like "ZStreams", or something similar.
|
|
||||||
|
|
||||||
- The C and zlib-supplied types int, uInt, long, uLong, etc. are
|
|
||||||
translated directly into Pascal types of similar sizes (Integer,
|
|
||||||
LongInt, etc.), to avoid namespace pollution. In particular,
|
|
||||||
there is no conversion of unsigned int into a Pascal unsigned
|
|
||||||
integer. The Word type is non-portable and has the same size
|
|
||||||
(16 bits) both in a 16-bit and in a 32-bit environment, unlike
|
|
||||||
Integer. Even if there is a 32-bit Cardinal type, there is no
|
|
||||||
real need for unsigned int in zlib under a 32-bit environment.
|
|
||||||
|
|
||||||
- Except for the callbacks, the zlib function interfaces are
|
|
||||||
assuming the calling convention normally used in Pascal
|
|
||||||
(__pascal for DOS and Windows16, __fastcall for Windows32).
|
|
||||||
Since the cdecl keyword is used, the old Turbo Pascal does
|
|
||||||
not work with this interface.
|
|
||||||
|
|
||||||
- The gz* function interfaces are not translated, to avoid
|
|
||||||
interfacing problems with the C runtime library. Besides,
|
|
||||||
gzprintf(gzFile file, const char *format, ...)
|
|
||||||
cannot be translated into Pascal.
