This function returns a dataset from an HDF5 file, given the identifier (StrID) of the dataset. To read a subset of the data, use H5D_READ instead.
            Examples
            file = FILEPATH('hdf5_test.h5', $
               SUBDIRECTORY=['examples','data'])
            data = H5_GETDATA(file, '/images/Eskimo')
            HELP, data
             
            IDL displays:

            Result = H5_GETDATA(Filename, StrID)
            Arguments
            Filename
