+<dt><strong>Purpose:</strong> </dt>
+ <dd>Retrieves a name of an object based on the object identifier.
+<dt><strong>Description:</strong>
+ <dd><code>H5Iget_name</code> retrieves a name for the object identified
+ by <code>obj_id</code>.
+ <p>
+ Up to <code>size</code> characters of the name are returned in
+ <code>name</code>; additional characters, if any, are not returned
+ to the user application.
+ <p>
+ If the length of the name, which determines the required
+ value of <code>size</code>, is unknown, a preliminary
+ <code>H5Iget_name</code> call can be made.
+ The return value of this call will be the size of the
+ object name.
+ That value can then be assigned to <code>size</code>
+ for a second <code>H5Iget_name</code> call,
+ which will retrieve the actual name.
+ <p>
+ If there is no name associated with the object identifier
+ or if the name is <code>NULL</code>, <code>H5Iget_name</code>
+ returns <code>0</code> (zero).
+ <p>
+ Note that an object in an HDF5 file may have multiple names,
+ varying according to the path through the HDF5 group
+ hierarchy used to reach that object.
+<dt><strong>Parameters:</strong>
+ <dl>
+ <dt><em>hid_t</em> <code>obj_id</code>
+ <dd>IN: Identifier of the object.
+ This identifier can refer to a group, dataset, or
+ named datatype.
+ <dt><em>char *</em><code>name</code>
+ <dd>OUT: A name associated with the identifier.
+ <dt><em>size_t size</em>
+ <dd>IN: The size of the <code>name</code> buffer.
+ </dl>
+<dt><strong>Returns:</strong>
+ <dd>Returns the length of the name if successful,
+ returning <code>0</code> (zero) if no name is associated with the identifier.
+ Otherwise returns a negative value.
