SYNOPSIS
#include
<openssl/ssl.h>
int
SSL_CTX_set_ssl_version
(SSL_CTX
*ctx, const SSL_METHOD
*method);
int

(SSL
*s, const SSL_METHOD
*method);
const SSL_METHOD *
SSL_get_ssl_method
(SSL
*ssl);
DESCRIPTION
SSL_CTX_set_ssl_version
()
sets a new default TLS/SSL method for
SSL objects newly created from this
ctx. SSL objects already created
with SSL_new(3) are not affected, except when
SSL_clear(3) is called.
SSL_set_ssl_method
()
sets a new TLS/SSL method for a particular
SSL object s. It may be reset
when SSL_clear(3) is called.
SSL_get_ssl_method
()
returns a function pointer to the TLS/SSL method set in
ssl.
The available method choices are described in SSL_CTX_new(3).
When SSL_clear(3) is called and no session is connected to an SSL object, the method of the SSL object is reset to the method currently set in the corresponding SSL_CTX object.
