</center>
<p>
The <code>start</code> array determines the starting coordinates
of the hyperslab to select.
<p>
The <code>stride</code> array chooses array locations
from the dataspace with each value in the <code>stride</code>
array determining how many elements to move in each dimension.
Setting a value in the <code>stride</code> array to 1 moves to
each element in that dimension of the dataspace; setting a value
of <code>2</code> in alocation in the <code>stride</code> array
moves to every other element in that dimension of the dataspace.
In other words, the <code>stride</code> determines the
number of elements to move from the <code>start</code> location
in each dimension.
Stride values of <code>0</code> are not allowed.
If the <code>stride</code> parameter is <code>NULL</code>,
a contiguous hyperslab is selected (as if each value in the
<code>stride</code> array were set to all 1's).
<p>
The <code>count</code> array determines how many blocks to
select from the dataspace, in each dimension.
<p>
The <code>block</code> array determines
the size of the element block selected from the dataspace.
If the <code>block</code> parameter is set to <code>NULL</code>,
the block size defaults to a single element in each dimension
(as if the <code>block</code> array were set to all
<code>1</code>'s).
<p>
For example, in a 2-dimensional dataspace, setting
<code>start</code> to [1,1],
<code>stride</code> to [4,4],
<code>count</code> to [3,7], and
<code>block</code> to [2,2]
selects 21 2x2 blocks of array elements starting with
location (1,1) and selecting blocks at locations
(1,1), (5,1), (9,1), (1,5), (5,5), etc.
<p>
Regions selected with this function call default to C order
iteration when I/O is performed.

<dt><strong>Description:</strong>
<dd><code>H5Sset_extent_simple</code> sets or resets the size of
an existing dataspace.
<p>
<code>rank</code> is the dimensionality, or number of
dimensions, of the dataspace.
<p>
<code>current_size</code> is an array of size <code>rank</code>
which contains the new size of each dimension in the dataspace.
<code>maximum_size</code> is an array of size <code>rank</code>
which contains the maximum size of each dimension in the
dataspace.
<p>
Any previous extent is removed from the dataspace, the dataspace
type is set to <code>H5S_SIMPLE</code>, and the extent is set as
specified.
