zlib/README
This directory contains the zlib package, which is not part of GCC but
shipped with GCC as convenience.
zlib 1.1.4 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
ZLIB DATA COMPRESSION LIBRARY
zlib 1.2.1 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://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 jloup@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 or descrip.mms.
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.

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 in
http://dogma.net/markn/articles/zlibtool/zlibtool.htm
The changes made in version 1.1.4 are documented in the file ChangeLog.
The only changes made since 1.1.3 are bug corrections:
- ZFREE was repeated on same allocation on some error conditions.
This creates a security problem described in
http://www.zlib.org/advisory-2002-03-11.txt
- Returned incorrect error (Z_MEM_ERROR) on some invalid data
- Avoid accesses before window for invalid distances with inflate window
less than 32K.
- force windowBits > 8 to avoid a bug in the encoder for a window size
of 256 bytes. (A complete fix will be available in 1.1.5).
The beta version 1.1.5beta includes many more changes. A new official
version 1.1.5 will be released as soon as extensive testing has been
completed on it.
The changes made in version 1.2.1 are documented in the file ChangeLog.
Unsupported third party contributions are provided in directory "contrib".

Notes for some targets:
- To build a Windows DLL version, include in a DLL project zlib.def, zlib.rc
and all .c files except example.c and minigzip.c; compile with -DZLIB_DLL
The zlib DLL support was initially done by Alessandro Iacopetti and is
now maintained by Gilles Vollant <info@winimage.com>. Check the zlib DLL
home page at http://www.winimage.com/zLibDll
From Visual Basic, you can call the DLL functions which do not take
a structure as argument: compress, uncompress and all gz* functions.
See contrib/visual-basic.txt for more information, or get
http://www.tcfb.com/dowseware/cmp-z-it.zip
- 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 on HP-UX 9.05 with some versions of /bin/cc. It works
with other compilers. Use "make test" to check your compiler.
- 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, BEOS and by some Mac compilers.
- For Turbo C the small model is supported only with reduced performance to
avoid any far allocation; it was tested with -DMAX_WBITS=11 -DMAX_MEM_LEVEL=3
- For PalmOs, see http://palmzlib.sourceforge.net/
- For PalmOs, see http://www.cs.uit.no/~perm/PASTA/pilot/software.html
Per Harald Myrvang <perm@stud.cs.uit.no>
- When building a shared, i.e. dynamic library on Mac OS X, the library must be
installed before testing (do "make install" before "make test"), since the
library location is specified in the library.

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.

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 set it
for the maximum speed.
inflate() sends new trees relatively often, so it is possibly set for a
smaller first level table than an application that has only one tree for
all the data. 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. It would be
interesting to see if optimizing the first level table for other
applications gave values within a bit or two of the flat code size.

These are files used to compile zlib under Borland C++ Builder 3.
zlib.bpg is the main project group that can be loaded in the BCB IDE and
loads all other *.bpr projects
zlib.bpr is a project used to create a static zlib.lib library with C calling
convention for functions.
zlib32.bpr creates a zlib32.dll dynamic link library with Windows standard
calling convention.
d_zlib.bpr creates a set of .obj files with register calling convention.
These files are used by zlib.pas to create a Delphi unit containing zlib.
The d_zlib.lib file generated isn't useful and can be deleted.
zlib.cpp, zlib32.cpp and d_zlib.cpp are used by the above projects.

// Important note about DLL memory management in a VCL DLL:
//
//
//
// If your DLL uses VCL and exports any functions that pass VCL String objects
// (or structs/classes containing nested Strings) as parameter or function
// results, you will need to build both your DLL project and any EXE projects
// that use your DLL with the dynamic RTL (the RTL DLL). This will change your
// DLL and its calling EXE's to use BORLNDMM.DLL as their memory manager. In
// these cases, the file BORLNDMM.DLL should be deployed along with your DLL
// and the RTL DLL (CP3240MT.DLL). To avoid the requiring BORLNDMM.DLL in
// these situations, pass string information using "char *" or ShortString
// parameters and then link with the static RTL.

UnZip 0.15 additionnal library
This unzip package allow extract file from .ZIP file, compatible with
PKZip 2.04g, WinZip, InfoZip tools and compatible.
Multi volume ZipFile (span) are not supported, and old compression used by old
PKZip 1.x are not supported.
See probdesc.zip from PKWare for specification of .ZIP format.
What is Unzip
The Zlib library support the deflate compression and the creation of gzip (.gz)
file. Zlib is free and small.
The .Zip format, which can contain several compressed files (.gz can containt
only one file) is a very popular format. This is why I've written a package for reading file compressed in Zipfile.
Using Unzip package
You need source of Zlib (get zlib111.zip and read zlib.h).
Get unzlb015.zip and read unzip.h (whith documentation of unzip functions)
The Unzip package is only two file : unzip.h and unzip.c. But it use the Zlib
files.
unztst.c is a simple sample program, which list file in a zipfile and display
README.TXT or FILE_ID.DIZ (if these files are found).
miniunz.c is a mini unzip program.
I'm also currenlyt writing a zipping portion (zip.h, zip.c and test with minizip.c)
Please email me for feedback.
I hope my source is compatible with Unix system, but I need your help for be sure
