        The zzip_seek function will perform a lseek(2) operation on a real/zipped file

        It will try to seek to the offset specified by offset, relative to whence, which is one of SEEK_SET,
       SEEK_CUR or SEEK_END.

        If the file-handle is wrapping a stat'able file then it will actually just perform a normal
       lseek(2)-call. Otherwise the relative offset is calculated, negative offsets are transformed into
       positive ones by rewinding the file, and then data is read until the offset is reached. This can make the
       function terribly slow, but this is how gzio implements it, so I'm not sure there is a better way without
       using the internals of the algorithm.

        The zzip_seek32 function is provided for users who can not use any largefile-mode.
