      1 ZLIB DATA COMPRESSION LIBRARY
      2 
      3 zlib 1.2.8 is a general purpose data compression library.  All the code is
      4 thread safe.  The data format used by the zlib library is described by RFCs
      5 (Request for Comments) 1950 to 1952 in the files
      6 http://www.ietf.org/rfc/rfc1950.txt (zlib format), rfc1951.txt (deflate format)
      7 and rfc1952.txt (gzip format).
      8 
      9 All functions of the compression library are documented in the file zlib.h
     10 (volunteer to write man pages welcome, contact zlib (a] gzip.org).  Two compiled
     11 examples are distributed in this package, example and minigzip.  The example_d
     12 and minigzip_d flavors validate that the zlib1.dll file is working correctly.
     13 
     14 Questions about zlib should be sent to <zlib (a] gzip.org>.  The zlib home page
     15 is http://zlib.net/ .  Before reporting a problem, please check this site to
     16 verify that you have the latest version of zlib; otherwise get the latest
     17 version and check whether the problem still exists or not.
     18 
     19 PLEASE read DLL_FAQ.txt, and the the zlib FAQ http://zlib.net/zlib_faq.html
     20 before asking for help.

     27   README-WIN32.txt This document
     28   ChangeLog        Changes since previous zlib packages
     29   DLL_FAQ.txt      Frequently asked questions about zlib1.dll
     30   zlib.3.pdf       Documentation of this library in Adobe Acrobat format
     31 
     32   example.exe      A statically-bound example (using zlib.lib, not the dll)
     33   example.pdb      Symbolic information for debugging example.exe
     34 
     35   example_d.exe    A zlib1.dll bound example (using zdll.lib)
     36   example_d.pdb    Symbolic information for debugging example_d.exe
     37 
     38   minigzip.exe     A statically-bound test program (using zlib.lib, not the dll)
     39   minigzip.pdb     Symbolic information for debugging minigzip.exe
     40 
     41   minigzip_d.exe   A zlib1.dll bound test program (using zdll.lib)
     42   minigzip_d.pdb   Symbolic information for debugging minigzip_d.exe
     43 
     44   zlib.h           Install these files into the compilers' INCLUDE path to
     45   zconf.h          compile programs which use zlib.lib or zdll.lib
     46 
     47   zdll.lib         Install these files into the compilers' LIB path if linking
     48   zdll.exp         a compiled program to the zlib1.dll binary
     49 
     50   zlib.lib         Install these files into the compilers' LIB path to link zlib
     51   zlib.pdb         into compiled programs, without zlib1.dll runtime dependency
     52                    (zlib.pdb provides debugging info to the compile time linker)
     53 
     54   zlib1.dll        Install this binary shared library into the system PATH, or
     55                    the program's runtime directory (where the .exe resides)
     56   zlib1.pdb        Install in the same directory as zlib1.dll, in order to debug
     57                    an application crash using WinDbg or similar tools.
     58 
     59 All .pdb files above are entirely optional, but are very useful to a developer
     60 attempting to diagnose program misbehavior or a crash.  Many additional
     61 important files for developers can be found in the zlib127.zip source package
     62 available from http://zlib.net/ - review that package's README file for details.

     67 The deflate format used by zlib was defined by Phil Katz.  The deflate and
     68 zlib specifications were written by L.  Peter Deutsch.  Thanks to all the
     69 people who reported problems and suggested various improvements in zlib; they
     70 are too numerous to cite here.
