NAME

       zlib - compression/decompression library

SYNOPSIS

       [see zlib.h for full description]

DESCRIPTION

       The  zlib  library  is a general purpose data compression library.  The
       code  is  thread  safe.   It   provides   in-memory   compression   and
       decompression functions, including integrity checks of the uncompressed
       data.  This version of the library supports only one compression method
       (deflation)  but other algorithms will be added later and will have the
       same stream interface.

       Compression can be done in a single  step  if  the  buffers  are  large
       enough  (for  example  if  an input file is mmap'ed), or can be done by
       repeated calls of the compression function.  In the  latter  case,  the
       application   must   provide  more  input  and/or  consume  the  output
       (providing more output space) before each call.

       The library also supports reading and writing files  in  gzip(1)  (.gz)
       format with an interface similar to that of stdio.

       The  library  does  not install any signal handler.  The decoder checks
       the consistency of the compressed data, so  the  library  should  never
       crash even in case of corrupted input.

       All  functions  of  the  compression library are documented in the file
       zlib.h.  The distribution  source  includes  examples  of  use  of  the
       library in the files example.c and minigzip.c.

       Changes  to  this  version  are  documented  in the file ChangeLog that
       accompanies the source, and are concerned primarily with bug fixes  and
       portability enhancements.

       A  Java implementation of zlib is available in the Java Development Kit
       1.1:

              java.util.zip.html

       A  Perl interface to zlib, written by Paul Marquess (pmqs@cpan.org), is
       available  at  CPAN  (Comprehensive  Perl   Archive   Network)   sites,
       including:

              http://www.cpan.org/modules/by-module/Compress/

       A  Python interface to zlib, written by A.M. Kuchling (amk@magnet.com),
       is available in Python 1.5 and later versions:

              http://www.python.org/doc/lib/module-zlib.html

       A   zlib   binding   for   tcl(1),   written   by    Andreas    Kupries
       (a.kupries@westend.com), is availlable at:

              http://www.westend.com/~kupries/doc/trf/man/man.html

       An experimental package to read and write files in .zip format, written
       on top of zlib by Gilles Vollant (info@winimage.com), is available at:

              http://www.winimage.com/zLibDll/unzip.html  and  also   in   the
              contrib/minizip directory of the main zlib web site.

       The  data  format used by the zlib library is described by RFC (Request
       for Comments) 1950 to 1952 in the files:

              http://www.ietf.org/rfc/rfc1950.txt (concerning zlib format)
              http://www.ietf.org/rfc/rfc1951.txt (concerning deflate format)
              http://www.ietf.org/rfc/rfc1952.txt (concerning gzip format)

       Mark Nelson (markn@ieee.org) wrote an article about zlib for  the  Jan.

REPORTING PROBLEMS

       Before reporting a problem, please check the zlib web  site  to  verify
       that  you have the latest version of zlib; otherwise, obtain the latest
       version and see if the problem still exists.  Please read the zlib  FAQ
       at:

              http://www.gzip.org/zlib/zlib_faq.html

       before   asking   for   help.    Send   questions  and/or  comments  to
       zlib@gzip.org, or (for the  Windows  DLL  version)  to  Gilles  Vollant
       (info@winimage.com).
