       gnutls_rehandshake - API function

       int gnutls_rehandshake(gnutls_session_t session);


       gnutls_session_t session
                   is a gnutls_session_t structure.


       This  function  will renegotiate security parameters with the client.  This should only be

       If  this  function  succeeds (returns 0), you must call the gnutls_handshake() function in
       order to negotiate the new parameters.

       Since TLS is full duplex  some  application  data  might  have  been  sent  during  peer's
       processing  of  this  message.  In  that  case  one should call gnutls_record_recv() until
       GNUTLS_E_REHANDSHAKE is returned to  clear  any  pending  data.  Care  must  be  taken  if
       rehandshake is mandatory to terminate if it does not start after some threshold.

       If  the  client  does  not  wish  to  renegotiate  parameters he will should with an alert
       message, thus the return code will be GNUTLS_E_WARNING_ALERT_RECEIVED and the  alert  will
       be GNUTLS_A_NO_RENEGOTIATION.  A client may also choose to ignore this message.


       GNUTLS_E_SUCCESS on success, otherwise an error.
