H5DS_SET_SCALE

Convert dataset dsid to a dimension scale, with optional name, dimname.

Procedure:

H5DS_SET_SCALE(dsid, dimname)

Signature:

herr_t H5DSset_scale(hid_t dsid, char *dimname)

SUBROUTINE H5DSset_scale_f(dsid, errcode, dimname)
    IMPLICIT NONE
    INTEGER(hid_t),   INTENT(in) :: dsid               ! The dataset to be made 
                                                       ! a Dimension Scale
    INTEGER :: errcode                                 ! Error code
    CHARACTER(LEN=*), INTENT(in), OPTIONAL :: dimname  ! The dimension name
END SUBROUTINE H5DSset_scale_f

Parameters:
hid_t dsid;IN: the dataset to be made a Dimension Scale
char *dimname;    IN: the dimension name (optional), NULL if the dimension has no name.

Description:

The dataset dsid is converted to a Dimension Scale dataset, as defined above. Creates the CLASS attribute, set to the value "DIMENSION_SCALE" and an empty REFERENCE_LIST attribute, as described in “HDF5 Dimension Scale Specification” (PDF, see section 4.2).

If dimname is specified, then an attribute called NAME is created, with the value dimname.

Fails if:

  • Bad arguments
  • If dsid is already a scale
  • If dsid is a dataset which already has dimension scales

If the dataset was created with the Table, Image, or Palette interface [9], it is not recommended to convert to a Dimension Scale. (These Datasets will have a CLASS Table, Image, or Palette.)

Returns:

Zero if succeed, negative if fail.

    int         rdata[DIM0][DIM1];          /* buffer for read */
 
    hid_t       file_id, dataset_id;        /* handles */
    hid_t       dataspace_id, memspace_id;
