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@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@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.

  25 The package zlib-1.2.8-win32-x86.zip will contain the following files:

  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.
