how to get the name for a dtype_id?

Hello,

when walking along a HDF5 file I was doing this:

  dtype_id = H5Dget_type (dset);

Now I want to get the name string for the retrived dtype_id.
But somhow I was not able to fiddle out by means of the documentation sections on H5D.

The best function call I was able to locate until now
was H5Dopen (...by_name...) - it is obviousely doing it in the "wrong" direction for me.

Can you please point me out to the function that returns the data type name to me?

Regards, Alex.
