13 int SSL_set_ssl_method(SSL *s, const SSL_METHOD *method);

18 SSL_CTX_set_ssl_version() sets a new default TLS/SSL B<method> for SSL objects
19 newly created from this B<ctx>. SSL objects already created with
20 L<SSL_new(3)> are not affected, except when
21 L<SSL_clear(3)> is being called.
23 SSL_set_ssl_method() sets a new TLS/SSL B<method> for a particular B<ssl>
24 object. It may be reset, when SSL_clear() is called.
26 SSL_get_ssl_method() returns a function pointer to the TLS/SSL method
31 The available B<method> choices are described in
34 When L<SSL_clear(3)> is called and no session is connected to
35 an SSL object, the method of the SSL object is reset to the method currently
36 set in the corresponding SSL_CTX object.
40 The following return values can occur for SSL_CTX_set_ssl_version()
41 and SSL_set_ssl_method():
47 The new choice failed, check the error stack to find out the reason.
51 The operation succeeded.
