ZLIB DATA COMPRESSION LIBRARY |
|
2
|
|
|
3
|
zlib 1.3.2 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
|
https://datatracker.ietf.org/doc/html/rfc1951 (zlib format), rfc1951.txt |
|
7
|
(deflate format), 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 [email protected]). 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. |

is https://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. |

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 https://zlib.net/ - review that package's README file for details. |

zlib specifications were written by L. Peter Deutsch. Thanks to all the |
