UnZip Wrapper for Borland Delphi

I wrote a Delphi unit to wrap the API of UnZip for Windows
(unzip32.dll). It allows static as well as dynamic linking. The wrapper
and a copy of the readme can be downloaded here:

   http://www.gerke-preussner.de/soft/libinfozip/delphiunzip.zip
   http://www.gerke-preussner.de/soft/libinfozip/readme.txt

It is about 335kB in size and comes with a well documented demo
application and test data. Feel free to add this contribution to the
UnZip distribution.


Note: So far I was unable to make use of the API functions Wiz_SetOpts()
and Wiz_SingleEntryUnzip(). They both cause an access violation in
unzip32.dll when called. I'm not too familiar with the internals of
UnZip, but it looks like the global variables are not initialized
properly (the CONSTRUCTGLOBALS() directive takes care of this for all
other API calls). Since there's not enough memory allocated for the 'G'
variable, assigning some properties crashes the DLL. Luckily, these two
functions are not really important to work with UnZip (do they have a
purpose outside the DLL at all or where they exported by accident?).
However, if anyone got a hint about what I'm missing to make them work
properly, I'd be glad to update the wrapper and show the correct usage
in the demo.


Regards,

Gerke Preussner
