| 1 | ZLIB DATA COMPRESSION LIBRARY |
| 2 | |
| 3 | zlib 1.2.13 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-1.2.13-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. |
