</pre>
<p class="item_name">PURPOSE</p>
<pre>  This file contains Fortran interfaces for <strong>H5A</strong> functions. It includes
  all the functions that are independent on whether the Fortran 2003 functions
  are enabled or disabled.
</pre>
<p class="item_name">NOTES</p>
<pre>                         *** IMPORTANT ***
  If you add a new <strong>H5A</strong> function you must add the function name to the
  Windows dll file 'hdf5_fortrandll.def' in the fortran/src directory.
  This is needed for Windows based operating systems.
