+     * H5Pset_file_space_strategy sets the file space management strategy for the file associated with fcpl_id to strategy.
      * There are four strategies that applications can select and they are described in the Parameters section.

      * @param strategy
      *            IN: The strategy for file space management.
-     *                Passing a value of zero (0) indicates that the value of strategy is not to be modified.
-     *                H5F_FILE_SPACE_ALL_PERSIST
-     *                        With this strategy, the free-space managers track the free space that results from the
-     *                        manipulation of HDF5 objects in the HDF5 file. The free space information is saved when the
-     *                        file is closed, and reloaded when the file is reopened. When space is needed for file metadata
-     *                        or raw data, the HDF5 library first requests space from the library's free-space managers.
-     *                        If the request is not satisfied, the library requests space from the aggregators. If the request
-     *                        is still not satisfied, the library requests space from the virtual file driver. That is, the
-     *                        library will use all of the mechanisms for allocating space.

-     *                        With this strategy, the free-space managers track the free space that results from the manipulation
-     *                        of HDF5 objects in the HDF5 file. The free space information is NOT saved when the file is closed
-     *                        and the free space that exists upon file closing becomes unaccounted space in the file.
-     *                        Like the previous strategy, the library will try all of the mechanisms for allocating space. When
-     *                        space is needed for file metadata or raw data, the library first requests space from the free-space
-     *                        managers. If the request is not satisfied, the library requests space from the aggregators. If the
-     *                        request is still not satisfied, the library requests space from the virtual file driver.
