Purpose:
[is this a bug fix? feature? ...]
Description:
[describe the bug, or describe the new feature, etc]
Solution:
[details about the changes, algorithm, etc...]
[Please as detail as you can since your own explanation is
better than others guessing it from the code.]
Platforms tested:
[machines you have tested the changed version. This is absolute
important. Test it out on at least two or three different platforms
such as Big-endian-32bit (SUN/IRIX), little-endian-32(LINUX) and
64-bit (IRIX64/UNICOS/DEC-ALPHA) would be good.]

<P>
|
|
The HDF5 library provides several interfaces, or APIs.
|
|
These APIs provide routines for creating, accessing, and manipulating
|
|
HDF5 files and objects.
|
|
<P>
|
|
The library itself is implemented in C. To facilitate the work of
|
|
FORTRAN90 and Java programmers, HDF5 function wrappers have been developed
|
|
in each of these languages.
|
|
At the time of this writing, a set of C++ wrappers is in development.
|
|
This tutorial discusses the use of the C functions and the FORTRAN wrappers.
|
|
<P>
|
|
All C routines in the HDF5 library begin with a prefix of the form <I>H5</I>*,
|
|
where * is one or two uppercase letters indicating the type of object on which the
|
|
function operates.
|
|
The FORTRAN wrappers come in the form of subroutines that begin with
|
|
<I>h5</I> and end with <I>_f</I>. The APIs are listed below:
