H5Pset_istore_k
(
hid_t fcpl_id
,
unsigned ik
)
H5Pset_istore_k
sets the size of the parameter
used to control the B-trees for indexing chunked datasets.
This function is valid only for file creation property lists.
ik
is one half the rank of a tree that stores
chunked raw data. On average, such a tree will be 75% full,
or have an average rank of 1.5 times the value of
ik
.
The HDF5 library uses (ik*2)
as the maximum # of entries before splitting a
B-tree node.
Since only 2 bytes are used in storing # of entries for a B-tree node in an HDF5 file,
(ik*2)
cannot exceed 65536
.
The default value for ik
is 32
.
