<h2>Identifier API Functions</h2>

This function provides a tool for working with object identifiers.

<strong>The FORTRAN90 Interface:</strong>

<font size=-1>
|
|
<i>In general, each FORTRAN90 subroutine performs exactly the same task
|
|
as the corresponding C function. The links below 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,
|
|
opens an external browser window displaying the FORTRAN90-specific
|
|
information. You will probably want to adjust the size and location of
|
|
this external window so that both browser windows are visible and to
|
|
facilitate moving easily between them.</i>

<dt><strong>Signature:</strong>
|

<dd><em>H5I_type_t</em> <code>H5Iget_type</code>(<em>hid_t</em> <code>obj_id</code>)
|
|
<dt><strong>Purpose:</strong>
|
|
<dd>Retrieves the type of an object.
|
|
<dt><strong>Description:</strong>
|
|
<dd><code>H5Iget_type</code> retrieves the type of the object
|
|
identified by <code>obj_id</code>.
|
|
<p>
|
|
Valid types returned by the function are
|
|
<table>
|
|
<tr><td width=200><code> H5I_FILE</code>
|
|
</td><td>File</td></tr>
|
|
<tr><td><code> H5I_GROUP</code>

|
|
</td><td>Dataset</td></tr>
|
|
<tr><td><code> H5I_ATTR</code>
|
|
</td><td>Attribute</td></tr>
|
|
</table>
|
|
If no valid type can be determined or the identifier
|
|
submitted is invalid, the function returns
|

|

|
|
This function is of particular value in determining the
|
|
type of object closing function (<code>H5Dclose</code>,
|
|
<code>H5Gclose</code>, etc.) to call after a call to
|
|
<code>H5Rdereference</code>.
|
|
<dt><strong>Parameters:</strong>
|
|
<dl>
|
|
<dt><em>hid_t</em> <code>obj_id</code>
|
|
<dd>IN: Object identifier whose type is to be determined.
|
|
</dl>
|
|
<dt><strong>Returns:</strong>
|
|
<dd>Returns the object type if successful;
|
|
otherwise <code>H5I_BADID</code>.
