11
12 int SSL_CTX_set_ssl_version(SSL_CTX *ctx, const SSL_METHOD *method);
13 int SSL_set_ssl_method(SSL *s, const SSL_METHOD *method);
14 const SSL_METHOD *SSL_get_ssl_method(SSL *ssl);

16=head1 DESCRIPTION
17
18SSL_CTX_set_ssl_version() sets a new default TLS/SSL B<method> for SSL objects
19newly created from this B<ctx>. SSL objects already created with
20L<SSL_new(3)|SSL_new(3)> are not affected, except when
21L<SSL_clear(3)|SSL_clear(3)> is being called.
22
23SSL_set_ssl_method() sets a new TLS/SSL B<method> for a particular B<ssl>
24object. It may be reset, when SSL_clear() is called.
25
26SSL_get_ssl_method() returns a function pointer to the TLS/SSL method
27set in B<ssl>.
28
29=head1 NOTES
30
31The available B<method> choices are described in
32L<SSL_CTX_new(3)|SSL_CTX_new(3)>.
33
34When L<SSL_clear(3)|SSL_clear(3)> is called and no session is connected to
35an SSL object, the method of the SSL object is reset to the method currently
36set in the corresponding SSL_CTX object.
