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
