+ * in the string, r, with the name of the nth realm specified on the
+ * first line of the kerberos config file (KRB_CONF, defined in "krb.h").
+ * It returns 0 (KSUCCESS) on success, and KFAILURE on failure.  If the
+ * config file does not exist, and if n=1, a successful return will occur
+ * with r = KRB_REALM (also defined in "krb.h").
+ *
+ * NOTE: for archaic & compatibility reasons, this routine will only return
+ * valid results when n = 1.
+ *
+ * For the format of the KRB_CONF file, see comments describing the routine
+ * krb_get_krbhst().
