                   zero of GNUTLS_KU_PEER

DESCRIPTION         top

       This function will update/refresh the session keys when the TLS
       protocol is 1.3 or better. The peer is notified of the update by
       sending a message, so this function should be treated similarly
       to gnutls_record_send() --i.e., it may return GNUTLS_E_AGAIN or

       When this flag GNUTLS_KU_PEER is specified, this function in
       addition to updating the local keys, will ask the peer to refresh
       its keys too.

       If the negotiated version is not TLS 1.3 or better this function
       will return GNUTLS_E_INVALID_REQUEST.

RETURNS         top

       GNUTLS_E_SUCCESS on success, otherwise a negative error code.
