Zlib based buffer compression


I am trying to use the zlib based compression for buffer
compression. In this case, I am using compress2 function.

class="language-cpp">compression_success=compress2((Bytef*)compressed_buffer,
&compressed_size,(const Bytef*)package_data.pData,
(uLongf)orig_size, 1);

And for decompression I am using
uncompress function.

class="language-cpp">uncompress_success=uncompress((Bytef*)destination,
&UnCompSize, (const Bytef*)package_data.pData,
package_data.cbData);

The problem is that the system tend to
be very slow. I have heard that the other functionalities of the zlib
compression library like inflate and deflate can be very useful.

What the hell is "zlib" compresion? I'm trying to unzip a
multi-volume archive but cant do it with winzip.
Is there any
other prgrams to do it with?
the files are :
kinst2.zip />kinst2.z01
kinst2.z02
kinst2.z03
kinst2.z04 />kinst2.z05
kinst2.z06
kinst2.z07
kinst2.z08 />/EDIT
Got the latest version of winzip, but can only open the
zip file. when I try to open the others, I get the message
"Cannot open file: it does not appear to be an valid
archive." How is this possible if I can open the first file?

Does anyone know how to use the Zlib compression library for Series 60
2.0? I've peeped at the various header files, such as ezcompressor.h
etc, but they are way too difficult to understand for me.
What I
want to do is compress a file.
Thanks for any help.

I have a lil problem. I've installed a cms (websitebaker) and i cant
install any modules or templates because my hosting company doesnt
have zlib activated.
my question is what are the steps i should
send to the hosting company on how to turn on / activate zlib (they
dont know how to). They are on a windows server.
If anyone can
let me know how to set it up on a windows server so i can forward to
them i would greatly appreciate it.

I found a pretty annoying and serious problem in iTextSharp's zlib
implementation. Very hard to reproduce because it depends on the
actual data going into the PDF but in some circumstances, the
following exception occurs:



System.IndexOutOfRangeException: Index was outside the
bounds of the array.
at System.util.zlib.Tree.d_code(Int32 dist)
at System.util.zlib.Deflate.compress_block(Int16[] ltree, Int16[]
dtree)
Web Development

I would like to activate Zlib compression through PHP. What code
should I use for the PHP.ini file. I'm a bit confused on the best way
of setting this up. rel="nofollow">http://php.net/manual/en/book.zlib.php
