<strong>The FORTRAN90 Interfaces:</strong>
<br>
<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>Purpose:</strong>
<dd>Adds an external file to the list of external files.
<dt><strong>Description:</strong>
<dd><code>H5Pset_external</code> adds an external file to the
list of external files.
<p>
If a dataset is split across multiple files then the files
should be defined in order. The total size of the dataset is
the sum of the <code>size</code> arguments for all the external files. If
the total size is larger than the size of a dataset then the
dataset can be extended (provided the data space also allows
the extending).
<p>
The <code>size</code> argument specifies number of bytes reserved
for data in the external file.
If <code>size</code> is set to <code>H5F_UNLIMITED</code>, the
external file can be of unlimited size and no more files can be added to
the external files list.
<dt><strong>Parameters:</strong>
<dl>
<dt><em>hid_t</em> <code>plist</code>
<dd>IN: Identifier of a dataset creation property list.
<dt><em>const char</em> <code>*name</code>
<dd>IN: Name of an external file.
<dt><em>off_t</em> <code>offset</code>
<dd>IN: Offset, in bytes, from the beginning of the file
to the location in the file where the data starts.
<dt><em>hsize_t</em> <code>size</code>
<dd>IN: Number of bytes reserved in the file for the data.
</dl>
<dt><strong>Returns:</strong>
<dd>Returns a non-negative value if successful;
otherwise returns a negative value.

<dt><strong>Purpose:</strong>
<dd>Sets a dataset fill value.
<dt><strong>Description:</strong>
<dd><code>H5Pset_fill_value</code> sets the fill value for a
dataset creation property list.
<p>
The <code>value</code> is interpreted as being of type
<code>type_id</code>. This need not be the same type
as the dataset, but the library must be able to convert
<code>value</code> to the dataset type when the dataset
is created.
<dt><strong>Notes:</strong>
<dd>If a fill value is set for a dataset (even if the
fill value is all zeros), the fill value will be written
to the file. If no fill value is set, then HDF5 relies on
the underlying file driver (usually a Unix file system)
to initialize unwritten parts of the file to zeros.
<p>
Creating a contiguous dataset with a fill value can be a
very expensive operation since the optimization has not
yet been implemented that would delay the writing of the
fill values until after some data has been written.
<dt><strong>Parameters:</strong>
<dl>
<dt><em>hid_t</em> <code>plist_id</code>
<dd>IN: Property list identifier.
<dt><em>hid_t</em> <code>type_id</code>,

)
<dt><strong>Purpose:</strong>
<dd>Adds a filter to the filter pipeline.
<dt><strong>Description:</strong>
<dd><code>H5Pset_filter</code> adds the specified
<code>filter</code> and corresponding properties to the
end of an output filter pipeline.
If <code>plist</code> is a dataset creation property list,
the filter is added to the permanent filter pipeline;
if <code>plist</code> is a dataset transfer property list,
the filter is added to the transient filter pipeline.
<p>
The array <code>cd_values</code> contains
<code>cd_nelmts</code> integers which are auxiliary data
for the filter. The integer values will be stored in the
dataset object header as part of the filter information.
<p>
The <code>flags</code> argument is a bit vector with
the following fields specifying certain general properties
of the filter:
<center>
<table align=center width="80%">
<tr valign=top>
<td valign=top><code>H5Z_FLAG_OPTIONAL</code></td>
<td> </td>
<td valign=top>If this bit is set then the filter is
optional. If the filter fails (see below) during an
<code>H5Dwrite()</code> operation then the filter is
just excluded from the pipeline for the chunk for which
it failed; the filter will not participate in the
pipeline during an <code>H5Dread()</code> of the chunk.
This is commonly used for compression filters: if the
compression result would be larger than the input then
the compression filter returns failure and the
uncompressed data is stored in the file. If this bit is
clear and a filter fails then <code>H5Dwrite()</code>
or <code>H5Dread()</code> also fails.</td>

<dt><strong>Purpose:</strong>

<dt><strong>Description:</strong>
<dd><code>H5Pset_meta_block_size</code> sets the
minimum size, in bytes, of metadata block allocations when
<code>H5FD_FEAT_AGGREGATE_METADATA</code> is set by a VFL driver.
<p>
Each <i>raw</i> metadata block is initially allocated to be of the
given size. Specific metadata objects (e.g., object headers,
local heaps, B-trees) are then sub-allocated from this block.
<p>
The default setting is 2048 bytes, meaning that the library
will attempt to aggregate metadata in at least 2K blocks in the file.
Setting the value to <code>0</code> (zero) with this function
will turn off metadata aggregation, even if the VFL driver attempts
to use the metadata aggregation strategy.
<p>
Metadata aggregation reduces the number of small data objects
in the file that would otherwise be required for metadata.
The aggregated block of metadata is usually written in a
single write action and always in a contiguous block,
potentially significantly improving library and application
performance.

<dt><strong>Description:</strong>
<dd><code>H5Pset_gc_references</code> sets the flag for

<p>
Dataset region references and other reference types use space
in an HDF5 file's global heap. If garbage collection is on

the heap might get corrupted. When garbage collection is off, however,
and the user re-uses a reference, the previous heap block will be
orphaned and not returned to the free heap space.

<em>double</em> <code>rdcc_w0</code>
)
<dt><strong>Purpose:</strong>
<dd>Sets the meta data cache and raw data chunk cache parameters.
<dt><strong>Description:</strong>
<dd><code>H5Pset_cache</code> sets
the number of elements (objects) in the meta data cache and
the number of elements, the total number of bytes, and
the preemption policy value in the raw data chunk cache.
<p>
The <em>plist_id</em> is a file access property list.
The number of elements (objects) in the meta data cache
and the raw data chunk cache are <em>mdc_nelmts</em> and
<em>rdcc_nelmts</em>, respectively.
The total size of the raw data chunk cache and the preemption policy
are <em>rdcc_nbytes</em> and <em>rdcc_w0</em>.
<p>
Any (or all) of the <code>H5Pget_cache()</code> pointer arguments
may be null pointers.
<p>
The <em>rdcc_w0</em> value should be between 0 and 1 inclusive and
indicates how much chunks that have been fully read are
favored for preemption. A value of zero means fully read
chunks are treated no differently than other chunks (the
preemption is strictly LRU) while a value of one means fully
read chunks are always preempted before other chunks.

<dl>
<dt><em>hid_t</em> <code>plist_id</code>
<dd>IN: Identifier of the file access property list.
<dt><em>int</em> <code>mdc_nelmts</code>
<dd>IN: Number of elements (objects) in the meta data cache.

)
<dt><strong>Purpose:</strong>
<dd>Indicates whether to cache hyperslab blocks during I/O.
<dt><strong>Description:</strong>
<dd>Given a dataset transfer property list, <code>H5Pset_hyper_cache</code>
indicates whether to cache hyperslab blocks during I/O,
a process which can significantly increase I/O speeds.
<p>
When working with hyperslab selections, it is possible to
significantly speed up I/O operations by retrieving an
entire hyperslab from the file in one operation and
caching it in memory.
The <code>cache</code> parameter specifies whether to turn
caching on for hyperslab I/O operations.
If <code>cache</code> is set to <code>1</code>,
caching is turned on;
if set to <code>0</code>, caching is turned off.
<p>
The parameter <code>limit</code> sets the maximum size of the
hyperslab block to cache. If a block is smaller than that limit,
it may still not be cached if no memory is available.
Setting <code>limit</code> to <code>0</code> (zero) indicates
no limitation on the size of block to attempt to cache.
<p>
The default is to cache blocks with no limit on block size
for serial I/O and to not cache blocks for parallel I/O.
<dt><strong>Parameters:</strong>
<dl>
<dt><em>hid_t</em> <code>plist</code>
<dd>IN: Dataset transfer property list identifier.
<dt><em>unsigned</em> <code>cache</code>
<dd>IN: A flag indicating whether caching is to be
set to on (<code>1</code>) or off (<code>0</code>).
<dt><em>unsigned</em> <code>limit</code>
<dd>IN: Maximum size of the hyperslab block to cache.
<code>0</code> (zero) indicates no limit.

<dt><strong>Purpose:</strong>
<dd>Sets type conversion and background buffers.
<dt><strong>Description:</strong>
<dd> Given a dataset transfer property list, <code>H5Pset_buffer</code>
sets the maximum size
for the type conversion buffer and background buffer and
optionally supplies pointers to application-allocated buffers.
If the buffer size is smaller than the entire amount of data
being transferred between the application and the file, and a type
conversion buffer or background buffer is required, then
strip mining will be used.
<p>
Note that there are minimum size requirements for the buffer.
Strip mining can only break the data up along the first dimension,
so the buffer must be large enough to accommodate a complete slice
that encompasses all of the remaining dimensions.
For example, when strip mining a 100x200x300 hyperslab
of a simple data space, the buffer must be large enough to
hold 1x200x300 data elements.
When strip mining a 100x200x300x150 hyperslab of a simple data space,
the buffer must be large enough to hold 1x200x300x150 data elements.
<p>
If <code>tconv</code> and/or <code>bkg</code> are null pointers,
then buffers will be allocated and freed during the data transfer.
<p>
The default value for the maximum buffer is 1 Mb.
<dt><strong>Parameters:</strong>
<dl>
<dt><em>hid_t</em> <code>plist</code>

The <code>alloc_info</code> and <code>free_info</code> parameters
can be used to pass along any required information to
the user's memory management routines.
<p>
In summary, if the user has defined custom memory management
routines, the name(s) of the routines are passed in the

<em>hid_t</em> <code>fapl_id</code>,
<em>const H5FD_mem_t *</em><code>memb_map</code>,
<em>const hid_t *</em><code>memb_fapl</code>,
<em>const char **</em><code>memb_name</code>,
<em>const haddr_t *</em><code>memb_addr</code>,
<em>hbool_t</em> <code>relax</code>
)
<dt><strong>Purpose:</strong>
<dd>Sets up use of the multi-file driver.
<dt><strong>Description:</strong>
<dd><code>H5Pset_fapl_multi</code> sets the file access property list
<code>fapl_id</code> to use the multi-file driver.
<p>
The multi-file driver enables different types of HDF5 data and
metadata to be written to separate files. These files are viewed
by the HDF5 library and the application as a single virtual HDF5 file
with a single HDF5 file address space.
The types of data that can be broken out into separate file include
raw data, the superblock, B-tree data, global heap data,
local heap data, and object headers.
At the programmer's discretion, two or more types of data can be
written the same file while other types of data are written to
separate files.
<p>
The array <code>memb_map</code> maps memory usage types to other
memory usage types and is the mechanism that allows the caller
to specify how many files are created.
The array contains <code>H5FD_MEM_NTYPES</code> entries,
which are either the value <code>H5FD_MEM_DEFAULT</code>
or a memory usage type.
The number of unique values determines the number of files
that are opened.
<p>
The array <code>memb_fapl</code> contains a property list
for each memory usage type that will be associated with a file.
<p>
The array <code>memb_name</code> should be a name generator
(a printf-style format with a %s which will be replaced with the
name passed to <code>H5FDopen()</code>, usually from
<code>H5Fcreate()</code> or <code>H5Fopen()</code>).
<p>
The array <code>memb_addr</code> specifies the offsets within the
virtual address space, from <code>0</code> (zero) to
<code>HADDR_MAX</code>, at wihch each type of data storage begins.
<p>
If <code>relax</code> is set to <code>TRUE</code> (or <code>1</code>),
then opening an existing file for read-only access will not fail
if some file members are missing.
This allows a file to be accessed in a limited sense if just the
meta data is available.
<p>
Default values for each of the optional arguments are as follows:
<dir>
<dl>
<dt><code>memb_map</code>
<dd>The default member map contains the value
<code>H5FD_MEM_DEFAULT</code> for each element.
<dt><code>memb_fapl</code>
<dd>The default value is <code>H5P_DEFAULT</code> for each element.
<dt><code>memb_name</code>
<dd>The default string is <code>%s-<i>X</i>.h5</code>
where <code><i>X</i></code> is one of the
following letters:
<dir>
<code>s</code> for <code>H5FD_MEM_SUPER</code>
<br>
<code>b</code> for <code>H5FD_MEM_BTREE</code>
<br>
<code>r</code> for <code>H5FD_MEM_DRAW</code>
<br>
<code>g</code> for <code>H5FD_MEM_GHEAP</code>
<br>
<code>l</code> for <code>H5FD_MEM_LHEAP</code>
<br>
<code>o</code> for <code>H5FD_MEM_OHDR</code>
</dir>
<dt><code>memb_addr</code>
<dd>The default value is <code>HADDR_UNDEF</code> for each element.
</dl>
</dir>
<dt><strong>Parameters:</strong>
<dl>
<dt><em>hid_t</em> <code>fapl_id</code>
<dd>IN: File access property list identifier.
<dt><em>const H5FD_mem_t *</em><code>memb_map</code>
<dd>IN: Maps memory usage types to other memory usage types.
<dt><em>const hid_t *</em><code>memb_fapl</code>
<dd>IN: Property list for each memory usage type.
<dt><em>const char **</em><code>memb_name</code>
<dd>IN: Name generator for names of member files.
<dt><em>const haddr_t *</em><code>memb_addr</code>
<dd>IN: The offsets within the virtual address space,
from <code>0</code> (zero) to <code>HADDR_MAX</code>,
at wihch each type of data storage begins.
<dt><em>hbool_t</em> <code>relax</code>
<dd>IN: Allows read-only access to incomplete file sets
when <code>TRUE</code>.
</dl>
<dt><strong>Returns:</strong>
<dd>Returns a non-negative value if successful.
Otherwise returns a negative value.
<dt><strong>Example:</strong>
<dd>The following code sample sets up a multi-file access property list
that partitions data into meta and raw files, each being
one-half of the address:

<em>const char *</em><code>raw_ext</code>,
<em>hid_t</em> <code>raw_plist_id</code>
)
<dt><strong>Purpose:</strong>
<dd>Emulates the old split file driver.
<dt><strong>Description:</strong>
<dd><code>H5Pset_fapl_split</code> is a compatability function that
enables the multi-file driver to emulate the split driver from
HDF5 Releases 1.0 and 1.2.
The split file driver stored metadata and raw data in separate files
but provide no mechanism for separating types of metadata.
<p>
<code>fapl_id</code> is a file access property list identifier.
<p>
<code>meta_ext</code> is the filename extension for the metadata file.
The extension is appended to the name passed to <code>H5FDopen</code>,
usually from <code>H5Fcreate</code> or <code>H5Fopen</code>,
to form the name of the metadata file.
If the string %s is used in the extension, it works like the
name generator as in <code>H5Pset_fapl_multi</code>.
<p>
<code>meta_plist_id</code> is the file access property list identifier
for the metadata file.
<p>
<code>raw_ext</code> is the filename extension for the raw data file.
The extension is appended to the name passed to <code>H5FDopen</code>,
usually from <code>H5Fcreate</code> or <code>H5Fopen</code>,
to form the name of the rawdata file.
If the string %s is used in the extension, it works like the
name generator as in <code>H5Pset_fapl_multi</code>.
<p>
<code>raw_plist_id</code> is the file access property list identifier
for the raw data file.
<dt><strong>Parameters:</strong>
<dl>
<dt>
<dt><em>hid_t</em> <code>fapl_id</code>,
<dd>IN: File access property list identifier.
<dt><em>const char *</em><code>meta_ext</code>,
<dd>IN: Metadata filename extension.
<dt><em>hid_t</em> <code>meta_plist_id</code>,
<dd>IN: File access property list identifier for the metadata file.
<dt><em>const char *</em><code>raw_ext</code>,
<dd>IN: Raw data filename extension.
<dt><em>hid_t</em> <code>raw_plist_id</code>
<dd>IN: File access property list identifier for the raw data file.
</dl>
<dt><strong>Returns:</strong>
<dd>Returns a non-negative value if successful.
Otherwise returns a negative value.
<dt><strong>Example:</strong>
<dd>
<pre>
/* Example 1: Both metadata and rawdata files are in the same */
/* directory. Use Station1-m.h5 and Station1-r.h5 as */
/* the metadata and rawdata files. */

<code>increment</code> specifies the increment by which allocated
memory is to be increased each time more memory is required.
<p>
If <code>backing_store</code> is set to <code>1</code>
(<code>TRUE</code>), the file contents are flushed to a file
with the same name as this core file when the file is closed
or access to the file is terminated in memory.
