NAME
       zzip_dirhandle, zzip_dirfd - ...
SYNOPSIS
       #include <zzip/lib.h>
       ZZIP_DIR * zzip_dirhandle((ZZIP_FILE * fp));
       int zzip_dirfd((ZZIP_DIR * dir));
DESCRIPTION
       The zzip_dirhandle function will just return fp->dir
       If a ZZIP_FILE is contained within a zip-file that one will be a valid
       pointer, otherwise a NULL is returned and the ZZIP_FILE wraps a real
       file.
       The zzip_dirfd function will just return dir->fd
       If a ZZIP_DIR does point to a zipfile then the file-descriptor of that
       zipfile is returned, otherwise a NULL is returned and the ZZIP_DIR
       wraps a real directory DIR (if you have dirent on your system).
