<!-- #EndLibraryItem --><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>.
