<dt><strong>Signature:</strong>
<dd><em>int</em> <code>H5Idec_ref</code>(<em>hid_t</em> <code>obj_id</code>)
<dt><strong>Purpose:</strong>
<dd>Decrements the reference count for an object.
<dt><strong>Description:</strong>
<dd><code>H5Idec_ref</code> decrements the reference count of the object
identified by <code>obj_id</code>.
<p>
The reference count for an object ID is attached to the information
about an object in memory and has no relation to the number of links to
an object on disk.
<p>
The reference count for a newly created object will be 1.
Reference counts for objects may be explicitly modified with this
function or with <code>H5Iinc_ref</code>.
When an object ID's reference count reaches zero, the object will be
closed.
Calling an object ID's 'close' function decrements the reference count
for the ID which normally closes the object, but
if the reference count for the ID has been incremented with
<code>H5Iinc_ref</code>, the object will only be closed when the
reference count
reaches zero with further calls to this function or the
object ID's 'close' function.
<p>
If the object ID was created by a collective parallel call (such as
<code>H5Dcreate</code>, <code>H5Gopen</code>, etc.), the reference
count should be modified by all the processes which have copies of
the ID. Generally this means that group, dataset, attribute, file
and named datatype IDs should be modified by all the processes and
that all other types of IDs are safe to modify by individual processes.
<p>
This function is of particular value when an application is maintaining
multiple copies of an object ID. The object ID can be incremented when
a copy is made. Each copy of the ID can then be safely closed or
decremented and the HDF5 object will be closed when the reference count
for that that object drops to zero.

<dt><strong>Description:</strong>
<dd><code>H5Idec_type_ref</code> decrements the reference count on an ID type.
The reference count is used by the library to indicate when an ID type can

<p>The <code>type</code> parameter is the identifier for the ID type whose

<dt><strong>Description:</strong>
<dd><code>H5Idestroy_type</code> deletes an entire ID type. All IDs of this

<p>
The type’s free function is called on all of the IDs which are deleted by
this function, freeing their memory. In addition, all memory used by this
type’s hash table is freed.
<p>
Since the <em>H5I_type_t</em> values of destroyed ID types are reused

<p>
<code>obj_id</code> can be a file, group, dataset, named datatype,

<p>
Note that the HDF5 Library permits an application to close a file
while objects within the file remain open.
If the file containing the object <code>obj_id</code>
is still open, <code>H5Iget_file_id</code> will retrieve the
existing file identifier.
If there is no existing file identifier for the file,

<p>
If the length of the name, which determines the required
value of <code>size</code>, is unknown, a preliminary

The return value of this call will be the size of the
object name.
That value can then be assigned to <code>size</code>

<p>
If there is no name associated with the object identifier
or if the name is <code>NULL</code>, <code>H5Iget_name</code>

<dd><em>void *</em> <code>H5Iobject_verify</code>(<em>hid_t</em> <code>id</code>,
<em>H5I_type_t</em> <code>id_type</code>)
<dt><strong>Purpose:</strong>
<dd>Returns the object referenced by id.
<dt><strong>Description:</strong>
<dd><code>H5Iobject_verify</code> returns a pointer to the memory referenced by
<code>id</code> after verifying that <code>id</code> is of type <code>id_type</code>.
This function is analogous to dereferencing a pointer in C with type checking.
<p>
<code>H5Iregister</code>(<em>H5I_type_t</em> <code>type</code>,
<em>void *</em><code>object</code>) takes an <em>H5I_type_t</em> and a
void pointer to an object, returning an <em>hid_t</em> of that type.
This <em>hid_t</em> can then be passed to <code>H5Iobject_verify</code>
along with its type to retrieve the object.
<p>
<code>H5Iobject_verify</code> does not change the ID it is called on in any
way (as opposed to <code>H5Iremove_verify</code>, which removes the ID from its
type’s hash table).
<dt><strong>Parameters:</strong>
<ul>
<table>
<tr>
<td valign="top"><em>hid_t</em> <code>id</code></td>
<td valign="top">IN: ID to be dereferenced</td>

</ul>
<dt><strong>Returns:</strong>

<dt><strong>Description:</strong>
<dd><code>H5Iregister</code> allocates space for a new ID and returns an identifier for it.
<p>
The <code>type</code> parameter is the identifier for the ID type to which
this new ID will belong. This identifier must have been created by a call

The <code>object</code> parameter is a pointer to the memory which the new

<dt><strong>Purpose:</strong>
<dd>Creates and returns a new ID type.
<dt><strong>Description:</strong>
<dd><code>H5Iregister_type</code> allocates space for a new ID type and
returns an identifier for it.
<p>
The <code>hash_size</code> parameter indicates the minimum size of the hash
table used to store IDs in the new type.
<p>
The <code>reserved</code> parameter indicates the number of IDs in this new
type to be reserved. Reserved IDs are valid IDs which are not associated with
any storage within the library.
<p>
The <code>free_func</code> parameter is a function pointer to a function
which returns an <em>herr_t</em> and accepts a <em>void *</em>. The purpose
of this function is to deallocate memory for a single ID. It will be called
by <code>H5Iclear_type</code> and <code>H5Idestroy_type</code> on each ID.
This function is NOT called by <code>H5Iremove_verify</code>.
The <em>void *</em> will be the same pointer which was passed in to
the <code>H5Iregister</code> function. The <code>free_func</code>
function should return 0 on success and -1 on failure.

<dt><strong>Purpose:</strong>
<dd>Removes an ID from internal storage.
<dt><strong>Description:</strong>
<dd><code>H5Iremove_verify</code> first ensures that <code>id</code> belongs to
<code>id_type</code>. If so, it removes <code>id</code> from internal storage
and returns the pointer to the memory it referred to. This pointer is the
same pointer that was placed in storage by <code>H5Iregister</code>.
If <code>id</code> does not belong to <code>id_type</code>,
then <code>NULL</code> is returned.
<p>
The <code>id</code> parameter is the ID which is to be removed from
internal storage. Note: this function does NOT deallocate the memory that
<code>id</code> refers to. The pointer returned by <code>H5Iregister</code>
must be deallocated by the user to avoid memory leaks.
<p>
The <code>type</code> parameter is the identifier for the ID type
which <code>id</code> is supposed to belong to. This identifier must
have been created by a call to <code>H5Iregister_type</code>.
<dt><strong>Parameters:</strong>

<dt><strong>Purpose:</strong>
<dd>Finds the memory referred to by an ID within the given ID type such that
some criterion is satisfied.
<dt><strong>Description:</strong>
<dd><code>H5Isearch</code> searches through a give ID type to find an object
that satisfies the criteria defined by <code>func</code>. If such an object
is found, the pointer to the memory containing this object is returned.
Otherwise, <code>NULL</code> is returned. To do this, <code>func</code> is
called on every member of <code>type</code>. The first member to satisfy
<code>func</code> is returned.
<p>
The <code>type</code> parameter is the identifier for the ID type which is
to be searched. This identifier must have been created by a call to
<code>H5Iregister_type</code>.
<p>
The parameter <code>func</code> is a function pointer to a function
which takes three parameters. The first parameter is a <em>void *</em>.
It will be a pointer the object to be tested. This is the same object
that was placed in storage using <code>H5Iregister</code>. The second
parameter is a <em>hid_t</em>. It is the ID of the object to be tested.
The last parameter is a <em>void *</em>. This is the <code>key</code> parameter
and can be used however the user finds helpful. Or it can simply be ignored
if it is not needed. <code>func</code> returns 0 if the object it is testing
does not pass its criteria. A non-zero value should be returned if the object
does pass its criteria.
<p>
The <code>key</code> parameter will be passed to the search function as a
parameter. It can be used to further define the search at run-time.
<dt><strong>Parameters:</strong>
<ul>
<table>
<tr>
<td valign="top"><em>H5I_type_t</em> <code>type</code></td>
<td valign="top">IN: The identifier of the type to be searched</td>

<dt><strong>Returns:</strong>
<dd>Returns a pointer to the object which satisfies the search function
on success, <code>NULL</code> on failure.
