gnutls_session_t session
    is a gnutls_session_t type.

void * session_id
    is a pointer to space to hold the session id.

size_t * session_id_size
    initially should contain the maximum session_id size and will be updated.

DESCRIPTION
Returns the current session ID. This can be used if you want to check if the next session you tried to resume was actually resumed. That is because resumed sessions share the same session ID with the original session. The session ID is selected by the server, that identify the current session. In all supported TLS protocols, the session id is less than GNUTLS_MAX_SESSION_ID_SIZE.

RETURNS
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise an error code is returned.
