Fortran90 Interface: h5rdereference_f
        
To dereference an object: 

Signature:
  SUBROUTINE h5rdereference_f(obj_id, ref, ref_obj_id, hdferr) 
    INTEGER(HID_T)    , INTENT(IN)  :: obj_id
    TYPE(hobj_ref_t_f), INTENT(IN)  :: ref
    INTEGER(HID_T)    , INTENT(OUT) :: ref_obj_id
    INTEGER           , INTENT(OUT) :: hdferr

Inputs:
  obj_id      - Valid identifier in file
  ref         - Object reference

Outputs:
  ref_obj_id  - Identifier of referenced object 
  hdferr      - Error code 
                 0 on success and -1 on failure 


To dereference a region:	
 
Signature:
  SUBROUTINE h5rdereference_f(obj_id, ref, ref_obj_id, hdferr)
    INTEGER(HID_T)         , INTENT(IN)  :: obj_id
    TYPE(hdset_reg_ref_t_f), INTENT(IN)  :: ref
    INTEGER(HID_T)         , INTENT(OUT) :: ref_obj_id
    INTEGER                , INTENT(OUT) :: hdferr 

Inputs:
  dset_id       - Valid identifier in file
  ref           - Object reference

Outputs:
  ref_obj_id    - Identifier of referenced object
  hdferr        - Error code 
                   0 on success and -1 on failure


Fortran2003 Interface: h5rdereference_f

Signature:
  SUBROUTINE h5rdereference_f(obj_id, ref_type, ref, ref_obj_id, hdferr)
    INTEGER(HID_T), INTENT(IN)  :: obj_id
    INTEGER       , INTENT(IN)  :: ref_type
    TYPE(C_PTR)   , INTENT(IN)  :: ref
    INTEGER(HID_T), INTENT(OUT) :: ref_obj_id
    INTEGER       , INTENT(OUT) :: hdferr

Inputs:
  obj_id     - Valid identifier for the file containing the
               referenced object or any object in that file.
  ref_type   - The reference type of ref.
  ref        - Object reference

Outputs:
  ref_obj_id - Identifier of referenced object
  hdferr     - Error code 
                0 on success and -1 on failure
