Синопсис (Synopsis)

#include <gnutls/gnutls.h>

int gnutls_session_get_id(gnutls_session_t session, void * session_id, size_t * session_id_size);


Аргументы (Arguments)

gnutls_session_t session
                   is a gnutls_session_t type.

void * session_id is a pointer to space to hold 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 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.


Возвращаемое значение (Return value)

On success, GNUTLS_E_SUCCESS (0) is returned, otherwise an error
       code is returned.
