! NAME
!  h5open_f
!
! PURPOSE
!  Initializes HDF5 Fortran interface.
!
! Outputs:
!  error - Returns 0 if successful and -1 if fails

! AUTHOR
!  Elena Pourmal
!  August 12, 1999
!
! HISTORY
!  Explicit Fortran interfaces were added for
!  called C functions (it is needed for Windows
!  port).  February 28, 2001
!
! Removed call to h5open_c since this may cause a problem for an
! application that uses HDF5 library outside HDF5 Fortran APIs.
