<h1>The Property List Interface (H5P)</h1>
|
|
|
|
<h2>1. Introduction</h2>
|
|
|
|
<p>The property list (a.k.a., template) interface provides a
|
|
mechanism for default named arguments for a C function
|
|
interface. A property list is a collection of name/value pairs
|
|
which can be passed to various other HDF5 functions to control
|
|
features that are typically unimportant or whose default values
|
|
are usually used.
|
|
|
|
<p>For instance, file creation needs to know various things such
|
|
as the size of the user-block at the beginning of the file, or
|
|
the size of various file data structures. Wrapping this
|
|
information in a property list simplifies the API by reducing
|
|
the number of arguments to <code>H5Fcreate()</code>.
|
|
|
|
<h2>2. General Property List Operations</h2>
|
|
|
|
<p>Property lists follow the same create/open/close paradigm as
|
|
the rest of the library.
|
|
|
|
<dl>
|
|
<dt><code>hid_t H5Pcreate (H5P_class_t <em>class</em>)</code>
|
|
<dd>A new property list can be created as an instance of some
|
|
property list class. The new property list is initialized
|
|
with default values for the specified class. The classes are:
|
|
|
|
<br><br>
|
|
<dl>
|
|
<dt><code>H5P_FILE_CREATE</code>
|
|
<dd>Properties for file creation. See <a href="Files.html">H5F</a>
|
|
for details about the file creation properties.
|
|
<dt><code>H5P_FILE_ACCESS</code>
|
|
<dd>Properties for file access. See <a href="Files.html">H5F</a>
|
|
for details about the file creation properties.
|
|
<dt><code>H5P_DATASET_CREATE</code>
|
|
<dd>Properties for dataset creation. See
|
|
<a href="Datasets.html">H5D</a> for details about dataset
|
|
creation properties.
|
|
<dt><code>H5P_DATASET_XFER</code>
|
|
<dd>Properties for raw data transfer. See
|
|
<a href="Datasets.html">H5D</a> for details about raw data
|
|
transfer properties.
|
|
</dl>
|
|
|
|
<br><br>
|
|
<dt><code>hid_t H5Pcopy (hid_t <em>plist</em>)</code>
|
|
<dd>A property list can be copied to create a new property
|
|
list. The new property list has the same properties and values
|
|
as the original property list.
|
|
|
|
<br><br>
|
|
<dt><code>herr_t H5Pclose (hid_t <em>plist</em>)</code>
|
|
<dd>All property lists should be closed when the application is
|
|
finished accessing them. This frees resources used by the
|
|
property list.
|
|
|
|
<br><br>
|
|
<dt><code>H5P_class_t H5Pget_class (hid_t <em>plist</em>)</code>
|
|
<dd>The class of which the property list is a member can be
|
|
obtained by calling this function. The property list classes
|
|
are defined above for <code>H5Pcreate()</code>.
