Hdf rm description

H5D_OPEN2 opens the existing dataset specified by a location identifier and name, loc_id and name, respectively. loc_id may be a file, group, dataset, named datatype or attribute.  If an attribute, dataset, or named datatype is specified for loc_id then the dataset will be opened at the location where the attribute, dataset, or named datatype is attached.

The dataset access property list, dapl_id, provides information regarding access to the dataset.

To conserve and release resources, the dataset should be closed when access is no longer required.

Hdf rm returnvals

Returns a dataset identifier if successful; otherwise returns a negative value.
