## HDF5 Fortran Required Calls

HDF5 Fortran applications must begin and end, respectively, with the subroutines described below. `h5open_f` initializes the HDF5 Fortran interface, providing the application with access to the HDF5 Library. `h5close_f` closes the HDF5 Fortran interface without closing the HDF5 Library, thereby leaving HDF5 available to other software that may require that resource.

#### h5open_f

#### h5close_f

## HDF5 Fortran Utility Functions

The HDF5 Fortran Library offers two utility functions to facilitate the development of HDF5 Fortran applications. `h5offsetof` is available only in Fortran 2003 environments; `h5kind_to_type` is available in any Fortran environment.

#### h5offsetof

#### h5kind_to_type
