# krb5_get_host_realm - Get the Kerberos realm names for a host.

krb5_error_code `krb5_get_host_realm`(krb5_context context, const char * host, char *** realmsp)

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

retval: | 0 Success ENOMEM Insufficient memory
return: | Kerberos error codes

Fill in realmsp with a pointer to a null-terminated list of realm names. If there are no known realms for the host, a list containing the referral (empty) realm is returned.

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.
