# krb5_get_fallback_host_realm

krb5_error_code `krb5_get_fallback_host_realm`(krb5_context context, krb5_data * hdata, char *** realmsp)

param: | [in] context - Library context [in] hdata - Host name (or NULL) [out] realmsp - Null-terminated list of realm names

Fill in realmsp with a pointer to a null-terminated list of realm names obtained through heuristics or insecure resolution methods which have lower priority than KDC referrals.

If host is NULL, the local host’s realms are determined.

Use `krb5_free_host_realm()` to release realmsp when it is no longer needed.
