- * H5Pset_file_space sets the file space management strategy for the file associated with fcpl_id to strategy.
+ * 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 fcpl_id
* IN: File creation property list identifier
* @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.
- * H5F_FILE_SPACE_ALL (Default file space management strategy)
- * 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.
- * H5F_FILE_SPACE_AGGR_VFD
- * With this strategy, the library does not track free space that results from the manipulation of HDF5
- * obejcts in the HDF5 file and the free space becomes unaccounted space in the file.
- * When space is needed for file metadata or raw data, the library first requests space from the
- * aggregators. If the request is not satisfied, the library requests space from the virtual file driver.
- * H5F_FILE_SPACE_VFD
- * With this strategy, the library does not track free space that results from the manipulation of HDF5
- * obejcts in the HDF5 file and the free space becomes unaccounted space in the file.
- * When space is needed for file metadata or raw data, the library requests space from the virtual file driver.
+ * H5F_FSPACE_STRATEGY_FSM_AGGR
+ * Mechanisms: free-space managers, aggregators, and virtual file drivers
+ * This is the library default when not set.
+ * H5F_FSPACE_STRATEGY_PAGE
+ * Mechanisms: free-space managers with embedded paged aggregation and virtual file drivers
+ * H5F_FSPACE_STRATEGY_AGGR
+ * Mechanisms: aggregators and virtual file drivers
+ * H5F_FSPACE_STRATEGY_NONE
+ * Mechanisms: virtual file drivers
+ * @param persist
+ * IN: True to persist free-space.
* @param threshold
* IN: The free-space section threshold. The library default is 1, which is to track all free-space sections.
* Passing a value of zero (0) indicates that the value of threshold is not to be modified.
