@deftypefun {int} {gnutls_record_get_state} (gnutls_session_t @var{session}, unsigned @var{read}, gnutls_datum_t * @var{mac_key}, gnutls_datum_t * @var{IV}, gnutls_datum_t * @var{cipher_key}, unsigned char [8] @var{seq_number})
@var{session}: is a @code{gnutls_session_t} type
@var{read}: if non-zero the read parameters are returned, otherwise the write
@var{mac_key}: the key used for MAC (if a MAC is used)
@var{IV}: the initialization vector or nonce used
@var{cipher_key}: the cipher key
@var{seq_number}: A 64-bit sequence number
This function will return the parameters of the current record state.
These are only useful to be provided to an external off-loading device
or subsystem. The returned values should be considered constant
and valid for the lifetime of the session.
In that case, to sync the state back you must call @code{gnutls_record_set_state()} .
@strong{Returns:} @code{GNUTLS_E_SUCCESS} on success, or an error code.
Since 3.4.0
