Arguments

h5obj

An object of class H5IdComponent representing a H5 object identifier (file, group, or dataset). See H5Fcreate(), H5Fopen(), H5Gcreate(), H5Gopen(), H5Dcreate(), or H5Dopen() to create an object of this kind.

name

The name of the attribute (character).

objname

order

See h5const("H5_ITER") for possible arguments.

Value

An object of class H5IdComponent representing a H5 attribute identifier.
