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 should reply 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.
RETURNS¶
GNUTLS_E_SUCCESS on success, otherwise a negative error code.
