You may want to take a look at the code of krenew, which is part of the
kstart package:

That will show all the basic techniques.

If you're renewing a ticket, you probably want to read the existing
principal name from the ticket cache.  But anyway, the problem that you're
having is that you're passing in the entire principal as the realm and not
passing anything for the actual principal.

    krb5_build_principal(ctx, &client, strlen("TEST12434.SE"),
                         "TEST12434.SE", "TEST", NULL);
