NAME

6       SSL_SESSION_get_protocol_version, SSL_SESSION_set_protocol_version -
7       get and set the session protocol version
8

SYNOPSIS

10        #include <openssl/ssl.h>
11
12        int SSL_SESSION_get_protocol_version(const SSL_SESSION *s);
13        int SSL_SESSION_set_protocol_version(SSL_SESSION *s, int version);
14

DESCRIPTION

16       SSL_SESSION_get_protocol_version() returns the protocol version number
17       used by session s.
18
19       SSL_SESSION_set_protocol_version() sets the protocol version associated
20       with the SSL_SESSION object s to the value version. This value should
21       be a version constant such as TLS1_3_VERSION etc. For example, this
22       could be used to set up a session based PSK (see
23       SSL_CTX_set_psk_use_session_callback(3)).
24

RETURN VALUES

26       SSL_SESSION_get_protocol_version() returns a number indicating the
27       protocol version used for the session; this number matches the
28       constants e.g.  TLS1_VERSION, TLS1_2_VERSION or TLS1_3_VERSION.
29
30       Note that the SSL_SESSION_get_protocol_version() function does not
31       perform a null check on the provided session s pointer.
32
33       SSL_SESSION_set_protocol_version() returns 1 on success or 0 on
34       failure.
