gnutls_record_get_state(3)

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
