ZLIB DATA COMPRESSION LIBRARY
zlib 1.2.3 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). These documents are also available in other
formats from ftp://ftp.uu.net/graphics/png/documents/zlib/zdoc-index.html
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 example.c which also tests that the library
is working correctly. Another example is given in the file minigzip.c. The
compression library itself is composed of all source files except example.c and
minigzip.c.
To compile all files and run the test program, follow the instructions given at
the top of Makefile. In short "make test; make install" should work for most
machines. For Unix: "./configure; make test; make install". For MSDOS, use one
of the special makefiles such as Makefile.msc. For VMS, use make_vms.com.
Questions about zlib should be sent to <zlib@gzip.org>, or to Gilles Vollant
<info@winimage.com> for the Windows DLL version. The zlib home page is
http://www.zlib.org or http://www.gzip.org/zlib/ 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://www.gzip.org/zlib/zlib_faq.html before asking
for help.
Mark Nelson <markn@ieee.org> wrote an article about zlib for the Jan. 1997
issue of Dr. Dobb's Journal; a copy of the article is available in
http://dogma.net/markn/articles/zlibtool/zlibtool.htm
The changes made in version 1.2.3 are documented in the file ChangeLog.
Unsupported third party contributions are provided in directory "contrib".
A Java implementation of zlib is available in the Java Development Kit
http://java.sun.com/j2se/1.4.2/docs/api/java/util/zip/package-summary.html
See the zlib home page http://www.zlib.org for details.
A Perl interface to zlib written by Paul Marquess <pmqs@cpan.org> is in the
CPAN (Comprehensive Perl Archive Network) sites
http://www.cpan.org/modules/by-module/Compress/
A Python interface to zlib written by A.M. Kuchling <amk@amk.ca> is
available in Python 1.5 and later versions, see
http://www.python.org/doc/lib/module-zlib.html
A zlib binding for TCL written by Andreas Kupries <a.kupries@westend.com> is
availlable at http://www.oche.de/~akupries/soft/trf/trf_zip.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 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, BEOS and by some Mac compilers.
- For PalmOs, see http://palmzlib.sourceforge.net/
- When building a shared, i.e. dynamic library on Mac OS X, the library must be
installed before testing (do "make install" before "make test"), since the
library location is specified in the library.
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.

See the main site http://www.gzip.org/zlib/ for places to download the
complete sources. Currently based on zlib-1.2.3
Note that these are not the complete zlib sources - the following
directories have been deleted since they are irrelevant for the
eCos support:
amiga/
as400/
contrib/
msdos/
old/
projects/
qnx/
win32/
Additionally, local changes has been made to the remaining files. Code
changes are marked by __ECOS__ (comments or definitions). Finally, the
headers zlib.h and zconf.h have been moved out of the directory into
../include.
crc32.c + crc32.h has also been removed as it is provided by services/crc/.
Note: zconf.h always defines __ECOS__. This is necessary to support
programs built outside of the eCos tree which may wish to use this
library (so those programs needn't worry about defining __ECOS__)

.TH ZLIB 3 "18 July 2005"
.SH NAME
zlib \- compression/decompression library
.SH SYNOPSIS
[see
.I zlib.h
for full description]
.SH DESCRIPTION
The
.I 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.
.LP
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.
.LP
The library also supports reading and writing files in
.IR gzip (1)
(.gz) format
with an interface similar to that of stdio.
.LP
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.
.LP
All functions of the compression library are documented in the file
.IR zlib.h .
The distribution source includes examples of use of the library
in the files
.I example.c
and
.IR minigzip.c .
.LP
Changes to this version are documented in the file
.I ChangeLog
that accompanies the source,
and are concerned primarily with bug fixes and portability enhancements.
.LP
A Java implementation of
.I zlib
is available in the Java Development Kit 1.1:

// Usage: #include <cyg/error/codes.h>
//
// Example:
//
// err=myfun();

// printf("myfun returned error: %s\n", str);

This contains a very limited set of Linux-compatibility headers, initially
just for getting JFFS2 to build.
Some things are simply stubs which don't _work_, to allow the JFFS2 code
to compile. Note that you may need to implement these _properly_ in order
to use these for making other Linux code work, or indeed for making the
JFFS2 NAND support work.
The non-working parts include, but are not limited to:
workqueue.h, wait.h, timer.h, spinlock.h, sched.h, compiler.h

//======================================================================
// The purpose of this header file is to replicate appropriate
// functionality from the target-side header file <pkgconf/infra.h>.
// This header file is intended to contain configuration options
// related to the implementation of the infrastructure, as opposed
// to how that infrastructure gets used by other packages. A good
// example would be a configuration option to control the size
// of the circular trace buffer.
//
// On the host side these things are handled by autoconf, and in
// particular the configure.in script will offer command-line
// arguments allowing the relevant options to be controlled.
// The relevant information will end up in <cyg/pkgconf/hostinfra.h>
# include <pkgconf/hostinfra.h>
// Some options should always be enabled in this header file.
#define CYGDBG_INFRA_DIAG_PRINTF_USE_VARARG
#define CYGDBG_INFRA_DEBUG_ASSERT_MESSAGE
#define CYGDBG_INFRA_DEBUG_TRACE_MESSAGE
// Other options should be decided on a package by package basis,
// e.g. whether or not assertions are used. On the host side it is
// not appropriate to control these globally, instead the infrastructure
// always provides the necessary functionality and it is up to the
// other parts of the system to decide whether or not the facilities
// get used.
// A third set of options deal with the environment, e.g. the sizes
// of various data types. autoconf macros take care of most of the
// work, but some translation is needed into eCos-style names to
// avoid namespace pollution.
// Process the definitions of SIZEOF_INT_P and SIZEOF_LONG to work
// out a sensible data type for CYG_ADDRESS and CYG_ADDRWORD.
