Reads the table attribute fill values

H5TBA_GET_FILL reads the table attribute fill values into the buffer dst_buf for the table specified by dset_id and dset_name located in loc_id.

A return value of 1 indicates that a fill value is present.

A return value of 0 indicates a fill value is not present.

A return value <0 indicates an error.
