H5Iget_type(h5identifier)
H5Iget_name(h5obj)
H5Iis_valid(h5identifier)

`h5identifier`	An object of class `H5IdComponent` representing a H5 identifier (file, group, dataset, dataspace, datatype, attribute). See e.g. `H5Fcreate`, `H5Fopen`, `H5Gcreate`, `H5Gopen`, `H5Dcreate`, `H5Dopen` to create an object of this kind.
`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.

Interface to the HDF5 C-library libhdf5. See http://www.hdfgroup.org/HDF5/doc/RM/RM_H5I.html for further details.

H5Iget_type returns the type of the H5 identifier, H5Iget_name the name of the object, and H5Iis_valid checks if the object is a valid H5 identifier.
