-as the corresponding C function. The links below go to the C function
+as the corresponding C function. The links below (electronic versions only) go to the C function
descriptions, which serve as general descriptions for both. A button,
under <strong>Non-C API(s)</strong> at the end of the C function description,

<dt><strong>Purpose:</strong>
- <dd>Reclaims VL datatype memory buffers.
+ <dd>Iterates over all selected elements in a dataspace.
<dt><strong>Description:</strong>
- <dd><code>H5Dvlen_reclaim</code> reclaims memory buffers created to
- store VL datatypes.
- <p>
- The <code>type_id</code> must be the datatype stored in the buffer.
- The <code>space_id</code> describes the selection for the memory buffer
- to free the VL datatypes within.
- The <code>plist_id</code> is the dataset transfer property list which
- was used for the I/O transfer to create the buffer.
- And <code>buf</code> is the pointer to the buffer to be reclaimed.
- <p>
- The VL structures (<code>hvl_t</code>) in the user's buffer are
- modified to zero out the VL information after the memory has been reclaimed.
+ <dd><code>H5Diterate</code> iterates over all the elements selected
+ in a memory buffer. The callback function is called once for each
+ element selected in the dataspace.
<p>
- If nested VL datatypes were used to create the buffer,
- this routine frees them <em>from the bottom up</em>, releasing all
- the memory without creating memory leaks.
+ The selection in the dataspace is modified so that any elements
+ already iterated over are removed from the selection if the
+ iteration is interrupted (by the <code>H5D_operator_t</code>
+ function returning non-zero) before the iteration is complete;
+ the iteration may then be re-started by the user where it left off.
+
<dt><strong>Parameters:</strong>

- <dd>IN: Identifier of the datatype.

</dl>
<dt><strong>Returns:</strong>
- <dd>Returns non-negative value if successful;
