H5P_SET_FILE_SPACE_STRATEGY
Sets the file space handling strategy and persisting free-space values for a file creation property list
Procedure:
H5P_SET_FILE_SPACE_STRATEGY ( fcpl, strategy, persist, threshold )
Signature:
herr_t H5Pset_file_space_strategy(
hid_t fcpl,
H5F_fspace_strategy_t strategy,
hbool_t persist,
hsize_t threshold )
Parameters:
id_t
fcpl | IN: The file creation property list identifier used to create a new file |
H5F_fspace_strategy_t strategy | IN: The file space handling strategy to be used. H5F_fspace_strategy_t is defined as: typedef enum H5F_fspace_strategy_t {
H5F_FSPACE_STRATEGY_FSM_AGGR = 0, /* FSM, Aggregators, VFD */
H5F_FSPACE_STRATEGY_PAGE = 1 /* Paged FSM, VFD */
H5F_FSPACE_STRATEGY_AGGR = 2 /* Aggregators, VFD */
H5F_FSPACE_STRATEGY_NONE = 3, /* VFD */
H5F_FSPACE_STRATEGY_NTYPES
} H5F_fspace_strategy_t;
|
hbool_t
persist | IN: A boolean value to indicate whether free space should be persistent or not |
hsize_t
threshold | IN: The smallest free-space section size that the free space manager will track |
Description:
H5P_SET_FILE_SPACE_STRATEGY sets the file space handling strategy, specifies persisting free-space or not (persist), and sets the free-space section size threshold in the file creation property list fcpl.
This setting cannot be changed for the life of the file.
As the H5F_FSPACE_STRATEGY_AGGR and H5F_FSPACE_STRATEGY_NONE strategies do not use the free-space managers, the persist and threshold settings will be ignored for those strategies.
Returns:
Returns a non-negative value if successful; otherwise returns a negative value.
