+
+Changes in 1.0.4 (24 Jul 96)
+- In very rare conditions, deflate(s, Z_FINISH) could fail to produce an EOF
+  bit, so the decompressor could decompress all the correct data but went

+  avail_out as zero but there is nothing to do
+- added memcmp for non STDC compilers

-                Frequently Asked Questions about zlib

-

-

-If your question is not there, please check the zlib home page

-http://www.zlib.org which may have more recent information.

-The lastest zlib FAQ is at http://www.gzip.org/zlib/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://www.zlib.org.

-

- 3. Where can I get a Visual Basic interface to zlib?

-

-    See

-        * http://www.dogma.net/markn/articles/zlibtool/zlibtool.htm

-        * contrib/visual-basic.txt in the zlib distribution

-        * 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 total 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.

-

- 6. Where's the zlib documentation (man pages, etc.)?

-

-    It's in zlib.h for the moment, and Francis S. Lin has converted it to a

-    web page zlib.html. Volunteers to transform this to Unix-style man pages,

-    please contact us (zlib@gzip.org). Examples of zlib usage are in the files

-    example.c and minigzip.c.

-

- 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?

-

-    make clean

-    ./configure -s

-    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.

-

-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.fastio.com/ (ClibPDF), or 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?

-

-    It should. 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.

-

-29. Does zlib work on MVS, OS/390, CICS, etc.?

-

-    We don't know for sure. We have heard occasional reports of success on

-    these systems. If you do use it on one of these, please provide us with

-    a report, instructions, and patches that we can reference when we get

-    these questions. 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 a 4K string space, other than the caller of

-    gzprintf() assuring that the output will not exceed 4K. 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.

-

-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://www.zlib.org/

-

-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. 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.

-

-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

-    specficiation 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. 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.

+
+                Frequently Asked Questions about zlib
+
+
+If your question is not there, please check the zlib home page
+http://www.zlib.org which may have more recent information.
+The lastest zlib FAQ is at http://www.gzip.org/zlib/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://www.zlib.org.
+
+ 3. Where can I get a Visual Basic interface to zlib?
+
+    See
+        * http://www.dogma.net/markn/articles/zlibtool/zlibtool.htm
+        * contrib/visual-basic.txt in the zlib distribution
+        * 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 total 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.
+
+ 6. Where's the zlib documentation (man pages, etc.)?
+
+    It's in zlib.h for the moment, and Francis S. Lin has converted it to a
+    web page zlib.html. Volunteers to transform this to Unix-style man pages,
+    please contact us (zlib@gzip.org). Examples of zlib usage are in the files
+    example.c and minigzip.c.
+
+ 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?
+
+    make clean
+    ./configure -s
+    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.
+
+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.fastio.com/ (ClibPDF), or 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?
+
+    It should. 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.
+
+29. Does zlib work on MVS, OS/390, CICS, etc.?
+
+    We don't know for sure. We have heard occasional reports of success on
+    these systems. If you do use it on one of these, please provide us with
+    a report, instructions, and patches that we can reference when we get
+    these questions. 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 a 4K string space, other than the caller of
+    gzprintf() assuring that the output will not exceed 4K. 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.
+
+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://www.zlib.org/
+
+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. 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.
+
+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

-ZLIB DATA COMPRESSION LIBRARY

-

-zlib 1.2.3 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://www.ietf.org/rfc/rfc1950.txt (zlib format), rfc1951.txt (deflate format)

-and rfc1952.txt (gzip format). These documents are also available in other

-formats from ftp://ftp.uu.net/graphics/png/documents/zlib/zdoc-index.html

-

-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 example.c which also tests that the library

-is working correctly. Another example is given in the file minigzip.c. The

-compression library itself is composed of all source files except example.c and

-minigzip.c.

-

-To compile all files and run the test program, follow the instructions given at

-the top of Makefile. In short "make test; make install" should work for most

-machines. For Unix: "./configure; make test; make install". For MSDOS, use one

-of the special makefiles such as Makefile.msc. 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://www.zlib.org or http://www.gzip.org/zlib/ 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

+ZLIB DATA COMPRESSION LIBRARY
+
+zlib 1.2.3 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://www.ietf.org/rfc/rfc1950.txt (zlib format), rfc1951.txt (deflate format)
+and rfc1952.txt (gzip format). These documents are also available in other
+formats from ftp://ftp.uu.net/graphics/png/documents/zlib/zdoc-index.html
+
+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 example.c which also tests that the library
+is working correctly. Another example is given in the file minigzip.c. The
+compression library itself is composed of all source files except example.c and
+minigzip.c.
+
+To compile all files and run the test program, follow the instructions given at
+the top of Makefile. In short "make test; make install" should work for most
+machines. For Unix: "./configure; make test; make install". For MSDOS, use one
+of the special makefiles such as Makefile.msc. 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://www.zlib.org or http://www.gzip.org/zlib/ 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://www.gzip.org/zlib/zlib_faq.html before asking
+for help.

-1. Compression algorithm (deflate)

-

-The deflation algorithm used by gzip (also zip and zlib) is a variation of

-LZ77 (Lempel-Ziv 1977, see reference below). It finds duplicated strings in

-the input data.  The second occurrence of a string is replaced by a

-pointer to the previous string, in the form of a pair (distance,

-length).  Distances are limited to 32K bytes, and lengths are limited

-to 258 bytes. When a string does not occur anywhere in the previous

-32K bytes, it is emitted as a sequence of literal bytes.  (In this

-description, `string' must be taken as an arbitrary sequence of bytes,

-and is not restricted to printable characters.)

-

-Literals or match lengths are compressed with one Huffman tree, and

-match distances are compressed with another tree. The trees are stored

-in a compact form at the start of each block. The blocks can have any

-size (except that the compressed data for one block must fit in

-available memory). A block is terminated when deflate() determines that

-it would be useful to start another block with fresh trees. (This is

-somewhat similar to the behavior of LZW-based _compress_.)

-

-Duplicated strings are found using a hash table. All input strings of

-length 3 are inserted in the hash table. A hash index is computed for

-the next 3 bytes. If the hash chain for this index is not empty, all

-strings in the chain are compared with the current input string, and

-the longest match is selected.

-

-The hash chains are searched starting with the most recent strings, to

-favor small distances and thus take advantage of the Huffman encoding.

-The hash chains are singly linked. There are no deletions from the

-hash chains, the algorithm simply discards matches that are too old.

-

-To avoid a worst-case situation, very long hash chains are arbitrarily

-truncated at a certain length, determined by a runtime option (level

-parameter of deflateInit). So deflate() does not always find the longest

-possible match but generally finds a match which is long enough.

-

-deflate() also defers the selection of matches with a lazy evaluation

-mechanism. After a match of length N has been found, deflate() searches for

-a longer match at the next input byte. If a longer match is found, the

-previous match is truncated to a length of one (thus producing a single

-literal byte) and the process of lazy evaluation begins again. Otherwise,

-the original match is kept, and the next match search is attempted only N

-steps later.

-

-The lazy match evaluation is also subject to a runtime parameter. If

-the current match is long enough, deflate() reduces the search for a longer

-match, thus speeding up the whole process. If compression ratio is more

-important than speed, deflate() attempts a complete second search even if

-the first match is already long enough.

-

-The lazy match evaluation is not performed for the fastest compression

-modes (level parameter 1 to 3). For these fast modes, new strings

-are inserted in the hash table only when no match was found, or

-when the match is not too long. This degrades the compression ratio

-but saves time since there are both fewer insertions and fewer searches.

-

-

-2. Decompression algorithm (inflate)

-

-2.1 Introduction

-

-The key question is how to represent a Huffman code (or any prefix code) so

-that you can decode fast.  The most important characteristic is that shorter

-codes are much more common than longer codes, so pay attention to decoding the

-short codes fast, and let the long codes take longer to decode.

-

-inflate() sets up a first level table that covers some number of bits of

-input less than the length of longest code.  It gets that many bits from the

-stream, and looks it up in the table.  The table will tell if the next

-code is that many bits or less and how many, and if it is, it will tell

-the value, else it will point to the next level table for which inflate()

-grabs more bits and tries to decode a longer code.

-

-How many bits to make the first lookup is a tradeoff between the time it

-takes to decode and the time it takes to build the table.  If building the

-table took no time (and if you had infinite memory), then there would only

-be a first level table to cover all the way to the longest code.  However,

-building the table ends up taking a lot longer for more bits since short

-codes are replicated many times in such a table.  What inflate() does is

-simply to make the number of bits in the first table a variable, and  then

-to set that variable for the maximum speed.

-

-For inflate, which has 286 possible codes for the literal/length tree, the size

-of the first table is nine bits.  Also the distance trees have 30 possible

-values, and the size of the first table is six bits.  Note that for each of

-those cases, the table ended up one bit longer than the ``average'' code

-length, i.e. the code length of an approximately flat code which would be a

-little more than eight bits for 286 symbols and a little less than five bits

-for 30 symbols.

-

-

-2.2 More details on the inflate table lookup

-

-Ok, you want to know what this cleverly obfuscated inflate tree actually

-looks like.  You are correct that it's not a Huffman tree.  It is simply a

-lookup table for the first, let's say, nine bits of a Huffman symbol.  The

-symbol could be as short as one bit or as long as 15 bits.  If a particular

-symbol is shorter than nine bits, then that symbol's translation is duplicated

-in all those entries that start with that symbol's bits.  For example, if the

-symbol is four bits, then it's duplicated 32 times in a nine-bit table.  If a

-symbol is nine bits long, it appears in the table once.

-

-If the symbol is longer than nine bits, then that entry in the table points

-to another similar table for the remaining bits.  Again, there are duplicated

-entries as needed.  The idea is that most of the time the symbol will be short

-and there will only be one table look up.  (That's whole idea behind data

-compression in the first place.)  For the less frequent long symbols, there

-will be two lookups.  If you had a compression method with really long

-symbols, you could have as many levels of lookups as is efficient.  For

-inflate, two is enough.

-

-So a table entry either points to another table (in which case nine bits in

-the above example are gobbled), or it contains the translation for the symbol

-and the number of bits to gobble.  Then you start again with the next

-ungobbled bit.

-

-You may wonder: why not just have one lookup table for how ever many bits the

-longest symbol is?  The reason is that if you do that, you end up spending

-more time filling in duplicate symbol entries than you do actually decoding.

-At least for deflate's output that generates new trees every several 10's of

-kbytes.  You can imagine that filling in a 2^15 entry table for a 15-bit code

-would take too long if you're only decoding several thousand symbols.  At the

-other extreme, you could make a new table for every bit in the code.  In fact,

-that's essentially a Huffman tree.  But then you spend two much time

-traversing the tree while decoding, even for short symbols.

-

-So the number of bits for the first lookup table is a trade of the time to

-fill out the table vs. the time spent looking at the second level and above of

-the table.

-

-Here is an example, scaled down:

-

-The code being decoded, with 10 symbols, from 1 to 6 bits long:

-

-A: 0

-B: 10

-C: 1100

-D: 11010

-E: 11011

-F: 11100

-G: 11101

-H: 11110

-I: 111110

-J: 111111

-

-Let's make the first table three bits long (eight entries):

-

-000: A,1

-001: A,1

-010: A,1

-011: A,1

-100: B,2

-101: B,2

-110: -> table X (gobble 3 bits)

-111: -> table Y (gobble 3 bits)

-

-Each entry is what the bits decode as and how many bits that is, i.e. how

-many bits to gobble.  Or the entry points to another table, with the number of

-bits to gobble implicit in the size of the table.

-

-Table X is two bits long since the longest code starting with 110 is five bits

-long:

-

-00: C,1

-01: C,1

-10: D,2

-11: E,2

-

-Table Y is three bits long since the longest code starting with 111 is six

-bits long:

-

-000: F,2

-001: F,2

-010: G,2

-011: G,2

-100: H,2

-101: H,2

-110: I,3

-111: J,3

-

-So what we have here are three tables with a total of 20 entries that had to

-be constructed.  That's compared to 64 entries for a single table.  Or

-compared to 16 entries for a Huffman tree (six two entry tables and one four

-entry table).  Assuming that the code ideally represents the probability of

-the symbols, it takes on the average 1.25 lookups per symbol.  That's compared

-to one lookup for the single table, or 1.66 lookups per symbol for the

-Huffman tree.

-

-There, I think that gives you a picture of what's going on.  For inflate, the

-meaning of a particular symbol is often more than just a letter.  It can be a

-byte (a "literal"), or it can be either a length or a distance which

-indicates a base value and a number of bits to fetch after the code that is

-added to the base value.  Or it might be the special end-of-block code.  The

-data structures created in inftrees.c try to encode all that information

-compactly in the tables.

-# configure script for zlib. This script is needed only if

-# you wish to build a shared library and your system supports them,

-# of if you need special compiler, flags or install directory.

-# Otherwise, you can just use directly "make test; make install"

-#

-# To create a shared library, use "configure --shared"; by default a static

-# library is created. If the primitive shared library support provided here

-# does not work, use ftp://prep.ai.mit.edu/pub/gnu/libtool-*.tar.gz

-#

-# To impose specific compiler or flags or install directory, use for example:

-#    prefix=$HOME CC=cc CFLAGS="-O4" ./configure

-# or for csh/tcsh users:

-#    (setenv prefix $HOME; setenv CC cc; setenv CFLAGS "-O4"; ./configure)

-# LDSHARED is the command to be used to create a shared library

-

-# Incorrect settings of CC or CFLAGS may prevent creating a shared library.

-# If you have problems, try without defining CC and CFLAGS before reporting

-# an error.

-  Generate tables for a byte-wise 32-bit CRC calculation on the polynomial:

-  x^32+x^26+x^23+x^22+x^16+x^12+x^11+x^10+x^8+x^7+x^5+x^4+x^2+x+1.

-

-  Polynomials over GF(2) are represented in binary, one bit per coefficient,

-  with the lowest powers in the most significant bit.  Then adding polynomials

-  is just exclusive-or, and multiplying a polynomial by x is a right shift by

-  one.  If we call the above polynomial p, and represent a byte as the

-  polynomial q, also with the lowest power in the most significant bit (so the

-  byte 0xb1 is the polynomial x^7+x^3+x+1), then the CRC is (q*x^32) mod p,

-  where a mod b means the remainder after dividing a by b.

-

-  This calculation is done using the shift-register method of multiplying and

-  taking the remainder.  The register is initialized to zero, and for each

-  incoming bit, x^32 is added mod p to the register if the bit is a one (where

-  x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by

-  x (which is shifting right by one and adding x^32 mod p if the bit shifted

-  out is a one).  We start with the highest power (least significant bit) of

-  q and repeat for all eight bits of q.

-

-  The first table is simply the CRC of all possible eight bit values.  This is

-  all the information needed to generate CRCs on data a byte at a time for all

-  combinations of CRC register values and incoming bytes.  The remaining tables

-  allow for word-at-a-time CRC calculation for both big-endian and little-

-  endian machines, where a word is four bytes.

+  Generate tables for a byte-wise 32-bit CRC calculation on the polynomial:
+  x^32+x^26+x^23+x^22+x^16+x^12+x^11+x^10+x^8+x^7+x^5+x^4+x^2+x+1.
+
+  Polynomials over GF(2) are represented in binary, one bit per coefficient,
+  with the lowest powers in the most significant bit.  Then adding polynomials
+  is just exclusive-or, and multiplying a polynomial by x is a right shift by
+  one.  If we call the above polynomial p, and represent a byte as the
+  polynomial q, also with the lowest power in the most significant bit (so the
+  byte 0xb1 is the polynomial x^7+x^3+x+1), then the CRC is (q*x^32) mod p,
+  where a mod b means the remainder after dividing a by b.
+
+  This calculation is done using the shift-register method of multiplying and
+  taking the remainder.  The register is initialized to zero, and for each
+  incoming bit, x^32 is added mod p to the register if the bit is a one (where
+  x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by
+  x (which is shifting right by one and adding x^32 mod p if the bit shifted
+  out is a one).  We start with the highest power (least significant bit) of
+  q and repeat for all eight bits of q.
+
+  The first table is simply the CRC of all possible eight bit values.  This is
+  all the information needed to generate CRCs on data a byte at a time for all
+  combinations of CRC register values and incoming bytes.  The remaining tables
+  allow for word-at-a-time CRC calculation for both big-endian and little-
+  endian machines, where a word is four bytes.

- *  ALGORITHM

- *

- *      The "deflation" process depends on being able to identify portions

- *      of the input text which are identical to earlier input (within a

- *      sliding window trailing behind the input currently being processed).

- *

- *      The most straightforward technique turns out to be the fastest for

- *      most input files: try all possible matches and select the longest.

- *      The key feature of this algorithm is that insertions into the string

- *      dictionary are very simple and thus fast, and deletions are avoided

- *      completely. Insertions are performed at each input character, whereas

- *      string matches are performed only when the previous match ends. So it

- *      is preferable to spend more time in matches to allow very fast string

- *      insertions and avoid deletions. The matching algorithm for small

- *      strings is inspired from that of Rabin & Karp. A brute force approach

- *      is used to find longer strings when a small match has been found.

- *      A similar algorithm is used in comic (by Jan-Mark Wams) and freeze

- *      (by Leonid Broukhis).

- *         A previous version of this file used a more sophisticated algorithm

- *      (by Fiala and Greene) which is guaranteed to run in linear amortized

- *      time, but has a larger average cost, uses more memory and is patented.

- *      However the F&G algorithm may be faster for some highly redundant

- *      files if the parameter max_chain_length (described below) is too large.

- *

- *  ACKNOWLEDGEMENTS

- *

- *      The idea of lazy evaluation of matches is due to Jan-Mark Wams, and

- *      I found it in 'freeze' written by Leonid Broukhis.

- *      Thanks to many people for bug reports and testing.

+
+/*
+ *  ALGORITHM
+ *
+ *      The "deflation" process depends on being able to identify portions
+ *      of the input text which are identical to earlier input (within a
+ *      sliding window trailing behind the input currently being processed).
+ *
+ *      The most straightforward technique turns out to be the fastest for
+ *      most input files: try all possible matches and select the longest.
+ *      The key feature of this algorithm is that insertions into the string
+ *      dictionary are very simple and thus fast, and deletions are avoided
+ *      completely. Insertions are performed at each input character, whereas
+ *      string matches are performed only when the previous match ends. So it
+ *      is preferable to spend more time in matches to allow very fast string
+ *      insertions and avoid deletions. The matching algorithm for small
+ *      strings is inspired from that of Rabin & Karp. A brute force approach
+ *      is used to find longer strings when a small match has been found.
+ *      A similar algorithm is used in comic (by Jan-Mark Wams) and freeze
+ *      (by Leonid Broukhis).
+ *         A previous version of this file used a more sophisticated algorithm
+ *      (by Fiala and Greene) which is guaranteed to run in linear amortized
+ *      time, but has a larger average cost, uses more memory and is patented.
+ *      However the F&G algorithm may be faster for some highly redundant
+ *      files if the parameter max_chain_length (described below) is too large.
+ *
+ *  ACKNOWLEDGEMENTS
+ *
+ *      The idea of lazy evaluation of matches is due to Jan-Mark Wams, and
+ *      I found it in 'freeze' written by Leonid Broukhis.
+ *      Thanks to many people for bug reports and testing.

-/*

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

-   and provides information on the unused input on return.  For Z_DATA_ERROR

-   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.

+   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.
