@deftypefun {int} {gnutls_handshake_set_random} (gnutls_session_t @var{session}, const gnutls_datum_t * @var{random}) @var{session}: is a @code{gnutls_session_t} type. @var{random}: a random value of 32-bytes This function will explicitly set the server or client hello random value in the subsequent TLS handshake. The random value should be a 32-byte value. Note that this function should not normally be used as gnutls will select automatically a random value for the handshake. This function should not be used when resuming a session. @strong{Returns:} @code{GNUTLS_E_SUCCESS} on success, or an error code. Since 3.1.9 @end deftypefun
