NAME

       gnutls_session_key_update - API function


SYNOPSIS

       #include <gnutls/gnutls.h>

       gnutls_session_key_update(3)   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  proto-
       col  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
