title: Simple way to unzip a .zip file using zlib
body: <p>Is there a simple example of how to unzip a .zip file and extract the files to a directory? I am currently using zlib, and while I understand that zlib does not directly deal with zip files, there seems to be several additional things in zlibs's "contrib" library. I noticed and read about "minizip", and after reading some documents and looking at some of the code, I do not see a simple example of how to unzip a .zip file and extract the files to a directory. </p>
  
  <p>I would like to find a platform independent way of doing so, but if that is not possible then I need to find a way for windows and mac.</p>
