Description:

HTML Wrap

class	hdf-rm-section

Given a reference, ref_ptr, to an attribute attached to an object, H5R_OPEN_ATTR opens the attribute attached to that object and returns an identifier.

The parameter rapl id is a reference access property list identifier for the reference. The access property list can be used to access external files that the reference points to (through a file access property list).

The parameter aapl_id is an attribute access property list identifier for the referenced attribute.

The attribute opened with this function should be closed with H5A_CLOSE when it is no longer needed.
