H5open(void)
H5open initialize the library.
When the HDF5 Library is employed in a C application,
this function is normally called automatically, but if you
find that an HDF5 library function is failing inexplicably,
try calling this function first.
If you wish to elimnate this possibility, it is safe to
routinely call H5open before an application
starts working with the library as there are no damaging
side-effects in calling it more than once.
When the HDF5 Library is employed in a Fortran90 application,
h5open_f initializes global variables
(for example, predefined types) and performs other tasks required
to initialize the HDF5 Fortran Library.
h5open_f and h5close_f are
required calls in HDF5 Fortran applications.
