NAME
       gnutls_record_get_state - API function

SYNOPSIS
       #include <gnutls/gnutls.h>

       int gnutls_record_get_state(gnutls_session_t session, unsigned read,
       gnutls_datum_t * mac_key, gnutls_datum_t * IV, gnutls_datum_t *
       cipher_key, unsigned char [8] seq_number);

ARGUMENTS
       gnutls_session_t session
                   is a gnutls_session_t type

       unsigned read
                   if non-zero the read parameters are returned, otherwise the
                   write

       gnutls_datum_t * mac_key
                   the key used for MAC (if a MAC is used)

       gnutls_datum_t * IV
                   the initialization vector or nonce used

       gnutls_datum_t * cipher_key
                   the cipher key

       unsigned char [8] seq_number
                   A 64-bit sequence number

DESCRIPTION
       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
       gnutls_record_set_state().

RETURNS
       GNUTLS_E_SUCCESS on success, or an error code.

       Since 3.4.0
