! PURPOSE
!  This file contains Fortran 90 interfaces for H5R functions. It contains
!  the same functions as H5Rff_F03.f90 but excludes the Fortran 2003 functions
!  and the interface listings. This file will be compiled instead of H5Rff_F03.f90
!  if Fortran 2003 functions are not enabled.

! NOTES
!                         *** IMPORTANT ***
!  If you add a new H5R 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.
