<title>Property List Interface (H5P)</title>
</head>
<body>
<h1>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>.
</dl>
[svn-r680] H5.user.html A little editorial cleanup. Added link to Ragged.html, Ragged Arrays. Added link to Environment.html, Environmental Variables and Configuration Parameters. Added link to Copyright.html. Ragged.html Added "Use at your own risk" notice. Environment.html New file for environmental variables and configuration parameters. Datatypes.html Added the following datatypes: H5T_NATIVE_HSIZE H5T_NATIVE_HSSIZE H5T_NATIVE_HERR H5T_NATIVE_HBOOL Section 8, "Data Conversions" Added named link tag to catch hyperlink from RM. Revised "Note:" to emphasize limited inate data-conversion capability. Copyright.html New file. Copyright statement, linked into User's Guide and Reference Manual. Glossary.html Unlinked for Beta. General Changed email link at bottom of "user guide level documents" (as contrasted with "developer guide level documents" listed on the lower half of the User's Guide front page) to HDF Help Desk, hdfhelp@ncsa.uiuc.edu.
