<P>
The HDF5 library provides several interfaces, and is currently implemented in
C. The APIs provide routines for accessing HDF5 files and creating and
manipulating HDF5 objects. All C routines in the HDF5 library begin with
a prefix of the form H5*, where * is a single letter indicating the object on
which the operation is to be performed. The APIs are listed below:
