# krb5_get_renewed_creds - Get renewed credential from KDC using an existing credential.

krb5_error_code `krb5_get_renewed_creds`(krb5_context context, krb5_creds * creds, krb5_principal client, krb5_ccache ccache, const char * in_tkt_service)

param: | [in] context - Library context [out] creds - Renewed credentials [in] client - Client principal name [in] ccache - Credential cache [in] in_tkt_service - Server principal string (or NULL)

retval: | 0 Success
return: | Kerberos error codes

This function gets a renewed credential using an existing one from ccache . If in_tkt_service is specified, it is parsed (with the realm part ignored) and used as the server principal of the credential; otherwise, the ticket-granting service is used.

If successful, the renewed credential is placed in creds .
