NAME
       gnutls_rehandshake - API function

SYNOPSIS
       #include <gnutls/gnutls.h>

       int gnutls_rehandshake(gnutls_session_t session);

ARGUMENTS
       gnutls_session_t session
		   is a gnutls_session_t structure.

DESCRIPTION
       This function will renegotiate security parameters with the client.  This should only be called in case of a server.

       This message informs the peer that we want to renegotiate parameters (perform a handshake).

       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_WARN-
       ING_ALERT_RECEIVED and the alert will be GNUTLS_A_NO_RENEGOTIATION.  A client may also choose to ignore this message.

RETURNS
       GNUTLS_E_SUCCESS on success, otherwise a negative error code.
