[svn-r985] Checking in changes from "HDF5 Release 1.0" CVS branch that have not yet been checked into "HDF5 Development" branch. General ======= Various "copy edit" types of repairs. Revisions to document cross-linking. Added structural links tying all docs together (banners at top and bottom of documents, similar to Reference Manual banners of the Beta release). Set background color to white in all documents. NCSAfooterlogo.gif hdf2.jpg New image files to make the documents more self-contained (i.e., to prevent loading images from NCSA and HDF home servers). index.html Redesigned to isolate links external to the installation in a single location. Intro to HDF5 ============= H5.intro.html Fixed banner linking Intro to other docs. Set all URLs to be relative within the distribution; nothing points back to the HDF server. Updates to "Limits of the Current Release" and "Changes in the Current Release." HDF5 User's Guide ================= Changed several User Guide section titles such that all sections that are primarily about a particular interface are now titled in the format "The xxxxx Interface (H5x)". H5.user.html Commented out links to developer docs since they are marked in MANIFEST as not being for distribution in the release. Removed 2nd and 3rd indices from page. Changed "freeform" lists of sections (TOCs) to aligned tables. Datatypes.html Removed the sentence "I'm deferring definition until later since they're probably not as important as the other data types." from Section 3.3, "Properties of Date and Time Atomic Types." Added info regarding 'char' versus 'string' datatypes. Added as Section 3.7, "Character and String Datatype Issues." References.html Commented out substantial material (at end of document) from References planning document that is not appropriate for the User Guide but that is worth keeping around. Groups.html Final edits from elimination of "current working group." HDF5 Reference Manual ===================== Removed "Draft" from the <title>__</title> lines. RM_H5Front.html Removed 2nd and 3rd indices from page. Changed "freeform" lists of sections (TOCs) to aligned tables. RM_H5F.html RM_H5P.html Add file mounting information.

<dt><strong>Signature:</strong>
<dd><em>herr_t</em> <code>H5garbage_collect</code>(<em>void</em>)
<dt><strong>Purpose:</strong>
<dd>Garbage collects on all free-lists of all types.
<dt><strong>Description:</strong>
<dd><code>H5garbage_collect</code> walks through all the garbage
collection routines of the library, freeing any unused memory.
<p>
It is not required that <code>H5garbage_collect</code> be called
at any particular time; it is only necessary in certain situations
where the application has performed actions that cause the library
to allocate many objects. The application should call
<code>H5garbage_collect</code> if it eventually releases those
objects and wants to reduce the memory used by the library from
the peak usage required.
<p>
The library automatically garbage collects all the free lists
when the application ends.
<dt><strong>Parameters:</strong>
<dl>
<dt>None.

<dt><strong>Returns:</strong>
<dd>Returns a non-negative value if successful;
otherwise returns a negative value.

<dt><strong>Signature:</strong>
<dd><em>herr_t</em> <code>H5dont_atexit</code>(<em>void</em>)
<dt><strong>Purpose:</strong>
<dd>Instructs library not to install <code>atexit</code> cleanup routine.
<dt><strong>Description:</strong>
<dd><code>H5dont_atexit</code> indicates to the library that an
<code>atexit()</code> cleanup routine should not be installed.
The major purpose for this is in situations where the
library is dynamically linked into an application and is
un-linked from the application before <code>exit()</code> gets
called. In those situations, a routine installed with
<code>atexit()</code> would jump to a routine which was
no longer in memory, causing errors.
<p>
In order to be effective, this routine <em>must</em> be called
before any other HDF function calls, and must be called each
time the library is loaded/linked into the application
(the first time and after it's been un-loaded).
<dt><strong>Parameters:</strong>
<dl>
<dt>None.

<dd><em>herr_t</em> <code>H5check_version</code>(<em>unsigned</em> <code>majnum</code>,
<em>unsigned</em> <code>minnum</code>,
<em>unsigned</em> <code>relnum</code>
)
<dt><strong>Purpose:</strong>
<dd>
<dt><strong>Description:</strong>
<dd><code>H5check_version</code> verifies that the arguments match the
version numbers compiled into the library. This function is intended
to be called by the user to verify that the version of the header files
compiled into the application matches the version of the HDF5 library
being used.
<p>
Due to the risks of data corruption or segmentation faults,
<code>H5check_version</code> causes the application to abort if the
version numbers do not match.
<p>
If the version numbers of the library do not match
the version numbers in the header files being checked, the library calls the
standard C function <code>abort()</code>.
<dt><strong>Parameters:</strong>
<dl>
<dt><em>unsigned </em><code>majnum</code>
<dd>IN: The major version of the library.
<dt><em>unsigned </em><code>minnum</code>
<dd>IN: The minor version of the library.
<dt><em>unsigned </em><code>relnum</code>
<dd>IN: The release number of the library.
