gnutls_session_get_id2 - API function
Синопсис (Synopsis)
#include <gnutls/gnutls.h>
int gnutls_session_get_id2(gnutls_session_t session,
gnutls_datum_t * session_id);
Аргументы (Arguments)

is a gnutls_session_t type.
gnutls_datum_t * session_id
will point to the session ID.
Описание (Description)
Returns the TLS session identifier. The session ID is selected by
the server, and in older versions of TLS was a unique identifier
shared between client and server which was persistent across
resumption. In the latest version of TLS (1.3) or TLS 1.2 with
session tickets, the notion of session identifiers is undefined
and cannot be relied for uniquely identifying sessions across
client and server.
In client side this function returns the identifier returned by
the server, and cannot be assumed to have any relation to session
resumption. In server side this function is guaranteed to return
a persistent identifier of the session since GnuTLS 3.6.4, which
may not necessarily map into the TLS session ID value. Prior to
that version the value could only be considered a persistent
identifier, under TLS1.2 or earlier and when no session tickets
were in use.
The session identifier value returned is always less than
GNUTLS_MAX_SESSION_ID_SIZE and should be treated as constant.
Возвращаемое значение (Return value)
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise an error
code is returned.
