ZLIB DATA COMPRESSION LIBRARY

zlib 1.2.10 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://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

PLEASE read the zlib FAQ http://zlib.net/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 at
http://marknelson.us/1997/01/01/zlib-engine/ .

The changes made in version 1.2.10 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 <pmqs@cpan.org> is available

  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.

1) Download and unpack the zlib tarball to some IFS directory.
   (i.e.: /path/to/the/zlib/ifs/source/directory)

   If the installed IFS command suppors gzip format, this is straightforward,
else you have to unpack first to some directory on a system supporting it,
then move the whole directory to the IFS via the network (via SMB or FTP).

ZLIB DATA COMPRESSION LIBRARY

zlib 1.2.10 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

PLEASE read DLL_FAQ.txt, and the the zlib FAQ http://zlib.net/zlib_faq.html

/*
    The 'zlib' compression library 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

/*
ZEXTERN int ZEXPORT inflateInit OF((z_streamp strm));

     Initializes the internal stream state for decompression.  The fields
   next_in, avail_in, zalloc, zfree and opaque must be initialized before by
   the caller.  In the current version of inflate, the provided input is not
   read or consumed.  The allocation of a sliding window will be deferred to
   the first call of inflate (if the decompression does not complete on the
   first call).  If zalloc and zfree are set to Z_NULL, inflateInit updates
   them to use default allocation functions.

     inflateInit returns Z_OK if success, Z_MEM_ERROR if there was not enough
   memory, Z_VERSION_ERROR if the zlib library version is incompatible with the
   version assumed by the caller, or Z_STREAM_ERROR if the parameters are
   invalid, such as a null pointer to the structure.  msg is set to null if
   there is no error message.  inflateInit does not perform any decompression.
   Actual decompression will be done by inflate().  So next_in, and avail_in,

  forced to flush.

  The detailed semantics are as follows.  inflate performs one or both of the
  following actions:

  - Decompress more input starting at next_in and update next_in and avail_in
    accordingly.  If not all input can be processed (because there is not
    enough room in the output buffer), then next_in and avail_in are updated
    accordingly, and processing will resume at this point for the next call of
    inflate().

  - Generate more output starting at next_out and update next_out and avail_out
    accordingly.  inflate() provides as much output as possible, until there is
    no more input data or no more space in the output buffer (see below about
    the flush parameter).

ZEXTERN int ZEXPORT compress OF((Bytef *dest,   uLongf *destLen,
                                 const Bytef *source, uLong sourceLen));
/*
     Compresses the source buffer into the destination buffer.  sourceLen is
   the byte length of the source buffer.  Upon entry, destLen is the total size
   of the destination buffer, which must be at least the value returned by
   compressBound(sourceLen).  Upon exit, destLen is the actual size of the
   compressed data.  compress() is equivalent to compress2() with a level
   parameter of Z_DEFAULT_COMPRESSION.

     compress returns Z_OK if success, Z_MEM_ERROR if there was not
   enough memory, Z_BUF_ERROR if there was not enough room in the output
   buffer.
*/

ZEXTERN int ZEXPORT compress2 OF((Bytef *dest,   uLongf *destLen,
                                  const Bytef *source, uLong sourceLen,
                                  int level));
/*
     Compresses the source buffer into the destination buffer.  The level
   parameter has the same meaning as in deflateInit.  sourceLen is the byte
   length of the source buffer.  Upon entry, destLen is the total size of the
   destination buffer, which must be at least the value returned by
   compressBound(sourceLen).  Upon exit, destLen is the actual size of the
   compressed data.

     compress2 returns Z_OK if success, Z_MEM_ERROR if there was not enough
   memory, Z_BUF_ERROR if there was not enough room in the output buffer,
   Z_STREAM_ERROR if the level parameter is invalid.
