<p>This class is a wrapper around GZIP file access functions in zlib. Unlike <a class="el" href="classQuaZip.html" title="ZIP archive.">QuaZip</a> classes, it doesn't allow reading from a GZIP file opened as QIODevice, for example, if your GZIP file is in QBuffer. It only provides QIODevice access to a GZIP file contents, but the GZIP file itself must be identified by its name on disk or by descriptor id. </p>
