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. 21 22 23 Manifest: 24 25 The package zlib-1.2.8-win32-x86.zip will contain the following files: 26 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. 63 64 65 Acknowledgments: 66 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. 71 72 73 Copyright notice: 74 75 (C) 1995-2012 Jean-loup Gailly and Mark Adler 76 77 This software is provided 'as-is', without any express or implied 78 warranty.
