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)

[in] context - Library context

[in] host - Host name (or NULL)

[out] realmsp - Null-terminated list of realm names

  • 0 Success
  • ENOMEM Insufficient memory
  • 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.
