<BODY>
<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:
