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://tools.ietf.org/html/rfc1950 (zlib format), rfc1951 (deflate format) and +rfc1952 (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). A usage example +of the library is given in the file test/example.c which also tests that +the library is working correctly. Another example is given in the file +test/minigzip.c. The compression library itself is composed of all source +files in the root directory. + +To compile all files and run the test program, follow the instructions given at +the top of Makefile.in. In short "./configure; make test", and if that goes +well, "make install" should work for most flavors of Unix. For Windows, use +one of the special makefiles in win32/ or contrib/vstudio/ . For VMS, use +make_vms.com. + +Questions about zlib should be sent to , or to Gilles Vollant + for the Windows DLL version. 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 the zlib FAQ http://zlib.net/zlib_faq.html before asking for help. + +Mark Nelson wrote an article about zlib for the Jan. 1997 +issue of Dr. Dobb's Journal; a copy of the article is available at +http://marknelson.us/1997/01/01/zlib-engine/ . + +The changes made in version 1.2.13 are documented in the file ChangeLog. + +Unsupported third party contributions are provided in directory contrib/ . + +zlib is available in Java using the java.util.zip package, documented at +http://java.sun.com/developer/technicalArticles/Programming/compression/ . + +A Perl interface to zlib written by Paul Marquess is available +at CPAN (Comprehensive Perl Archive Network) sites, including +http://search.cpan.org/~pmqs/IO-Compress-Zlib/ . + +A Python interface to zlib written by A.M. Kuchling is +available in Python 1.5 and later versions, see +http://docs.python.org/library/zlib.html . + +zlib is built into tcl: http://wiki.tcl.tk/4610 . + +An experimental package to read and write files in .zip format, written on top +of zlib by Gilles Vollant , is available in the +contrib/minizip directory of zlib. + + +Notes for some targets: + +- For Windows DLL versions, please see win32/DLL_FAQ.txt + +- For 64-bit Irix, deflate.c must be compiled without any optimization. With + -O, one libpng test fails. The test works in 32 bit mode (with the -n32 + compiler flag). The compiler bug has been reported to SGI. + +- zlib doesn't work with gcc 2.6.3 on a DEC 3000/300LX under OSF/1 2.1 it works + when compiled with cc. + +- On Digital Unix 4.0D (formely OSF/1) on AlphaServer, the cc option -std1 is + necessary to get gzprintf working correctly. This is done by configure. + +- zlib doesn't work on HP-UX 9.05 with some versions of /bin/cc. It works with + other compilers. Use "make test" to check your compiler. + +- gzdopen is not supported on RISCOS or BEOS. + +- For PalmOs, see http://palmzlib.sourceforge.net/ + + +Acknowledgments: + + The deflate format used by zlib was defined by Phil Katz. The deflate and + zlib specifications were written by L. Peter Deutsch. Thanks to all the + people who reported problems and suggested various improvements in zlib; they + are too numerous to cite here. + +Copyright notice: + + (C) 1995-2022 Jean-loup Gailly and Mark Adler + + This software is provided 'as-is', without any express or implied + warranty.
