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 * ci-
pher_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
