,

)
H5Pset_sym_k
sets the size of parameters used to
control the symbol table nodes.
This function is valid only for file creation property lists.
Passing in a value of zero (0
) for
one of the parameters retains the current value.
ik
is one half the rank of a tree that stores a symbol
table for a group. Internal nodes of the symbol table are on
average 75% full. That is, the average rank of the tree is
1.5 times the value of ik
.
lk
is one half of the number of symbols that can
be stored in a symbol table node. A symbol table node is the
leaf of a symbol table tree which is used to store a group.
When symbols are inserted randomly into a group, the group's
symbol table nodes are 75% full on average. That is, they
contain 1.5 times the number of symbols specified by
lk
.
