NAME
SSL_CTX_set_ssl_version, SSL_set_ssl_method, SSL_get_ssl_method -
choose a new TLS/SSL method
SYNOPSIS
#include <openssl/ssl.h>
int SSL_CTX_set_ssl_version(SSL_CTX *ctx, const SSL_METHOD *method);
int SSL_set_ssl_method(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 being called.
SSL_set_ssl_method() sets a new TLS/SSL method for a particular ssl
object. It may be reset, when SSL_clear() is called.
SSL_get_ssl_method() returns a function pointer to the TLS/SSL method
set in ssl.

NOTES
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.
