+ ! ref - An object or dataset region reference.
+ !
+ ! Outputs:
+ ! name - A name associated with the referenced object or dataset ptr.
+ ! hdferr - Returns 0 if successful and -1 if fails.
+ !
+ ! Optional parameters:
+ ! size - The size of the name buffer, returning 0 (zero) if no name is associated
