SSL_SESSION_GET_PROTOCOL_VERSION(3ossl) OpenSSL
NAME
SSL_SESSION_get_protocol_version, SSL_SESSION_set_protocol_version -
get and set the session protocol version
SYNOPSIS
#include <openssl/ssl.h>
int SSL_SESSION_get_protocol_version(const SSL_SESSION *s);
int SSL_SESSION_set_protocol_version(SSL_SESSION *s, int version);
DESCRIPTION
SSL_SESSION_get_protocol_version() returns the protocol version number
used by session s.
SSL_SESSION_set_protocol_version() sets the protocol version associated
with the SSL_SESSION object s to the value version. This value should
be a version constant such as TLS1_3_VERSION etc. For example, this
could be used to set up a session based PSK (see
SSL_CTX_set_psk_use_session_callback(3)).
RETURN VALUES
SSL_SESSION_get_protocol_version() returns a number indicating the
protocol version used for the session; this number matches the
constants e.g. TLS1_VERSION, TLS1_2_VERSION or TLS1_3_VERSION.
Note that the SSL_SESSION_get_protocol_version() function does not
perform a null check on the provided session s pointer.
SSL_SESSION_set_protocol_version() returns 1 on success or 0 on
failure.
