=head1 NAME
|
|
|
|
SSL_SESSION_get_protocol_version,
|
|
SSL_SESSION_set_protocol_version
|
|
- get and set the session protocol version
|
|
|
|
=head1 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);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
SSL_SESSION_get_protocol_version() returns the protocol version number used
|
|
by session B<s>.
|
|
|
|
SSL_SESSION_set_protocol_version() sets the protocol version associated with the
|
|
SSL_SESSION object B<s> to the value B<version>. This value should be a version
|
|
constant such as B<TLS1_3_VERSION> etc. For example, this could be used to set
|
|
up a session based PSK (see L<SSL_CTX_set_psk_use_session_callback(3)>).
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
SSL_SESSION_get_protocol_version() returns a number indicating the protocol
|
|
version used for the session; this number matches the constants I<e.g.>
|
|
B<TLS1_VERSION>, B<TLS1_2_VERSION> or B<TLS1_3_VERSION>.
|
|
|
|
Note that the SSL_SESSION_get_protocol_version() function
|
|
does B<not> perform a null check on the provided session B<s> pointer.
|
|
|
|
SSL_SESSION_set_protocol_version() returns 1 on success or 0 on failure.
