  2. =head1 NAME
  3. SSL_SESSION_get_protocol_version,
  4. SSL_SESSION_set_protocol_version
  5. - get and set the session protocol version
  6. =head1 SYNOPSIS
  7. #include <openssl/ssl.h>
  8. int SSL_SESSION_get_protocol_version(const SSL_SESSION *s);
  9. int SSL_SESSION_set_protocol_version(SSL_SESSION *s, int version);
  10. =head1 DESCRIPTION
  11. SSL_SESSION_get_protocol_version() returns the protocol version number used
  12. by session B<s>.
  13. SSL_SESSION_set_protocol_version() sets the protocol version associated with the
  14. SSL_SESSION object B<s> to the value B<version>. This value should be a version
  15. constant such as B<TLS1_3_VERSION> etc. For example, this could be used to set
  16. up a session based PSK (see L<SSL_CTX_set_psk_use_session_callback(3)>).
  17. =head1 RETURN VALUES
  18. SSL_SESSION_get_protocol_version() returns a number indicating the protocol
  19. version used for the session; this number matches the constants I<e.g.>
  20. B<TLS1_VERSION>, B<TLS1_2_VERSION> or B<TLS1_3_VERSION>.
  21. Note that the SSL_SESSION_get_protocol_version() function
  22. does B<not> perform a null check on the provided session B<s> pointer.
  23. SSL_SESSION_set_protocol_version() returns 1 on success or 0 on failure.
