NAME
       gnutls_session_key_update - API function

SYNOPSIS
       #include <gnutls/gnutls.h>

       int gnutls_session_key_update(gnutls_session_t session, unsigned flags);

ARGUMENTS
       gnutls_session_t session
                   is a gnutls_session_t type.

       unsigned flags
                   zero of GNUTLS_KU_PEER

DESCRIPTION
       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
       GNUTLS_E_INTERRUPTED.

       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
       GNUTLS_E_SUCCESS on success, otherwise a negative error code.

SINCE
       3.6.3
