  2. =head1 NAME
  3. SSL_CTX_set_ssl_version, SSL_set_ssl_method, SSL_get_ssl_method
  4. - choose a new TLS/SSL method
  5. =head1 SYNOPSIS
  6. #include <openssl/ssl.h>
  7. int SSL_CTX_set_ssl_version(SSL_CTX *ctx, const SSL_METHOD *method);
  8. int SSL_set_ssl_method(SSL *s, const SSL_METHOD *method);
  9. const SSL_METHOD *SSL_get_ssl_method(const SSL *ssl);
  10. =head1 DESCRIPTION
  11. SSL_CTX_set_ssl_version() sets a new default TLS/SSL B<method> for SSL objects
  12. newly created from this B<ctx>. SSL objects already created with
  13. L<SSL_new(3)> are not affected, except when
  14. L<SSL_clear(3)> is being called.
  15. SSL_set_ssl_method() sets a new TLS/SSL B<method> for a particular B<ssl>
  16. object. It may be reset, when SSL_clear() is called.
  17. SSL_get_ssl_method() returns a function pointer to the TLS/SSL method
  18. set in B<ssl>.
  19. =head1 NOTES
  20. The available B<method> choices are described in
  21. L<SSL_CTX_new(3)>.
  22. When L<SSL_clear(3)> is called and no session is connected to
  23. an SSL object, the method of the SSL object is reset to the method currently
  24. set in the corresponding SSL_CTX object.
  25. =head1 RETURN VALUES
  26. The following return values can occur for SSL_CTX_set_ssl_version()
  27. and SSL_set_ssl_method():
  28. =over 4
  29. =item Z<>0
  30. The new choice failed, check the error stack to find out the reason.
  31. =item Z<>1
  32. The operation succeeded.
