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. |

23 | Manifest: |
24 | |
25 | The package zlib-1.2.13-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. |

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. |
