gnutls_handshake - This is the main function in the handshake protocol.
int gnutls_handshake(gnutls_session_t session);
- gnutls_session_t session
is a gnutls_session_t structure.
This function does the handshake of the TLS/SSL protocol,
and initializes the TLS connection.
This function will fail if any problem is encountered,
and will return a negative error code. In case of a client,
if the client has asked to resume a session, but the server couldn't,
then a full handshake will be performed.
The non-fatal errors such as GNUTLS_E_AGAIN and GNUTLS_E_INTERRUPTED
interrupt the handshake procedure, which should be later be resumed.
Call this function again, until it returns 0; cf.
gnutls_record_get_direction() and gnutls_error_is_fatal().
If this function is called by a server after a rehandshake request then
GNUTLS_E_GOT_APPLICATION_DATA or GNUTLS_E_WARNING_ALERT_RECEIVED
may be returned. Note that these are non fatal errors, only in the
specific case of a rehandshake. Their meaning is that the client
rejected the rehandshake request.
