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 lastest 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. Pointers to the
|
||||
precompiled DLL are found in the zlib web site at http://zlib.net/ .
|
||||
|
||||
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 1.2.12 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
|
||||
http://marknelson.us/1997/01/01/zlib-engine/ .
|
||||
|
||||
The changes made in version 1.2.12 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, documented at
|
||||
http://java.sun.com/developer/technicalArticles/Programming/compression/ .
|
||||
|
||||
A Perl interface to zlib written by Paul Marquess <pmqs@cpan.org> is available
|
||||
at CPAN (Comprehensive Perl Archive Network) sites, including
|
||||
http://search.cpan.org/~pmqs/IO-Compress-Zlib/ .
|
||||
|
||||
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 (formely 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.
|
||||
|
||||
- For PalmOs, see http://palmzlib.sourceforge.net/

zlib specifications were written by L. Peter Deutsch. Thanks to all the

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
|
||||

Version 1.01e, February 12th, 2005
|
||||
|
||||
Copyright (C) 1998-2005 Gilles Vollant
|
||||
|
||||
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)

* even emit a stored file instead of a stored block (saving 5 bytes).
|

strm provides the memory allocation functions and window buffer on input,

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
|
||||
are not correct, i.e. strm is Z_NULL or the state was not initialized.

/*
|

Decode literal, length, and distance codes and write out the resulting
|
||||
literal and match bytes until either not enough input or output is
|
||||
available, an end-of-block is encountered, or a data error is encountered.
|
||||
When large enough input and output buffers are supplied to inflate(), for
|
||||
example, a 16K input buffer and a 64K output buffer, more than 95% of the
|
||||
inflate execution time is spent in this routine.
|
||||
|
||||
Entry assumptions:
|
||||
|
||||
state->mode == LEN
|
||||
strm->avail_in >= 6
|
||||
strm->avail_out >= 258
|
||||
start >= strm->avail_out
|
||||
state->bits < 8
|
||||
|
||||
On return, state->mode is one of:
|
||||
|
||||
LEN -- ran out of enough output space or enough available input
|
||||
TYPE -- reached end of block code, inflate() to interpret next block
|
||||
BAD -- error in block data
|
||||
|
||||
Notes:
|
||||
|
||||
- The maximum input bits used by a length/distance pair is 15 bits for the
|
||||
length code, 5 bits for the length extra, 15 bits for the distance code,
|
||||
and 13 bits for the distance extra. This totals 48 bits, or six bytes.
|
||||
Therefore if strm->avail_in >= 6, then there is enough input to avoid
|
||||
checking for available input while decoding.
|
||||
|
||||
- The maximum bytes that a single length/distance pair can output is 258
|
||||
bytes, which is the maximum length that can be coded. inflate_fast()
|
||||
requires strm->avail_out >= 258 for each loop to avoid checking for
|
||||
output space.

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 inftrees.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.

Decompresses the source buffer into the destination buffer. *sourceLen is

the byte length of the source buffer. Upon entry, *destLen is the total size

*destLen is the size of the decompressed data and *sourceLen is the number

first unused input byte.

uncompress returns Z_OK if success, Z_MEM_ERROR if there was not enough
