Name: H5set_free_list_limits
Signature:
herr_t H5set_free_list_limits( int reg_global_lim, int reg_list_lim, int arr_global_lim, int arr_list_lim, int blk_global_lim, int blk_list_lim )

Purpose:
Sets free-list size limits.

Description:
H5set_free_list_limits sets size limits on all types of free lists. The HDF5 library uses free lists internally to manage memory. The types of free lists used are as follows:

The parameters specify global and per-list limits; for example, reg_global_limit and reg_list_limit limit the accumulated size of all regular free lists and the size of each individual regular free list, respectively. Therefore, if an application sets a 1Mb limit on each of the global lists, up to 4Mb of total storage might be allocated, 1Mb for each of the regular, array, block, and factory type lists.

The settings specified for block free lists are duplicated for factory free lists. Therefore, increasing the global limit on block free lists by x bytes will increase the potential free list memory usage by 2x bytes.

Using a value of -1 for a limit means that no limit is set for the specified type of free list.

Parameters:

Returns:
Returns a non-negative value if successful; otherwise returns a negative value.

Fortran90 Interface:
None.
