id_t fcplIN: The file creation property list identifier used to create a new file
H5F_fspace_strategy_t strategyIN: 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 persistIN: A boolean value to indicate whether free space should be persistent or not

.

hsize_t thresholdIN: The smallest free-space section size that the free space manager will track

.

SET_

space

FILE_

strategy

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.
