ZLIB DATA COMPRESSION LIBRARY
|
|
|
|
|
|
|
|
|
|
zlib 1.2.4 is a general purpose data compression library. All the code is
|
|
|
|
|
thread safe. The data format used by the zlib library is described by RFCs
|
|
|
|
|
(Request for Comments) 1950 to 1952 in the files
|
|
|
|
|
http://www.ietf.org/rfc/rfc1950.txt (zlib format), rfc1951.txt (deflate format)
|
|
|
|
|
and rfc1952.txt (gzip format).
|
|
|
|
|
|
|
|
|
|
All functions of the compression library are documented in the file zlib.h
|
|
|
|
|
(volunteer to write man pages welcome, contact zlib@gzip.org). Two compiled
|
|
|
|
|
examples are distributed in this package, example and minigzip. The example_d
|
|
|
|
|
and minigzip_d flavors validate that the zlib1.dll file is working correctly.
|
|
|
|
|
|
|
|
|
|
Questions about zlib should be sent to <zlib@gzip.org>. The zlib home page
|
|
|
|
|
is http://zlib.net/ . Before reporting a problem, please check this site to
|
|
|
|
|
verify that you have the latest version of zlib; otherwise get the latest
|
|
|
|
|
version and check whether the problem still exists or not.
|
|
|
|
|
|
|
|
|
|
PLEASE read DLL_FAQ.txt, and the the zlib FAQ http://zlib.net/zlib_faq.html
|
|
|
|

before asking for help.

zlib.h Install these files into the compilers' INCLUDE path to
|
|
|
|
|
zconf.h compile programs which use zlib.lib or zdll.lib
|
|
|
|
|
|
|
|
|
|
zdll.lib Install these files into the compilers' LIB path if linking
|
|
|
|
|
zdll.exp a compiled program to the zlib1.dll binary
|
|
|
|
|
|
|
|
|
|
zlib.lib Install these files into the compilers' LIB path to link zlib
|
|
|
|
|
zlib.pdb into compiled programs, without zlib1.dll runtime dependency
|
|
|
|
|
(zlib.pdb provides debugging info to the compile time linker)
|
|
|
|
|
|
|
|
|
|
zlib1.dll Install this binary shared library into the system PATH, or
|
|
|
|
|
the program's runtime directory (where the .exe resides)
|
|
|
|
|
zlib1.pdb Install in the same directory as zlib1.dll, in order to debug
|
|
|
|
|
an application crash using WinDbg or similar tools.
|
|
|
|
|
|
|
|
|
|
All .pdb files above are entirely optional, but are very useful to a developer
|
|
|
|
|
attempting to diagnose program misbehavior or a crash. Many additional
|
|
|
|
|
important files for developers can be found in the zlib124.zip source package
|
|
|
|
|
available from http://zlib.net/ - review that package's README file for details.

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

people who reported problems and suggested various improvements in zlib; they
