<CODE>SSL_CTX_set_ssl_version()</CODE> sets a new default TLS/SSL <STRONG>method</STRONG> for SSL objects newly created from this <STRONG>ctx</STRONG>. SSL objects already created with
<A HREF="../ssl/SSL_new.html#">SSL_new(3)</A> are not affected, except when
<A HREF="../ssl/SSL_clear.html#">SSL_clear(3)</A> is being called.

</P>
<P>
<CODE>SSL_set_ssl_method()</CODE> sets a new TLS/SSL <STRONG>method</STRONG> for a particular <STRONG>ssl</STRONG>
object. It may be reset, when <CODE>SSL_clear()</CODE> is called.

</P>
<P>
<CODE>SSL_get_ssl_method()</CODE> returns a function pointer to the TLS/SSL
method set in <STRONG>ssl</STRONG>.

When <A HREF="../ssl/SSL_clear.html#">SSL_clear(3)</A> is called and no session is connected to an SSL object, the method of the
