=head1 NAME
SSL_CTX_set_ssl_version, SSL_set_ssl_method, SSL_get_ssl_method
- choose a new TLS/SSL method
=head1 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);
=head1 DESCRIPTION
SSL_CTX_set_ssl_version() sets a new default TLS/SSL B<method> for SSL objects
newly created from this B<ctx>. SSL objects already created with
L<SSL_new(3)> are not affected, except when
L<SSL_clear(3)> is being called.
SSL_set_ssl_method() sets a new TLS/SSL B<method> for a particular B<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 B<ssl>.
=head1 NOTES
The available B<method> choices are described in
L<SSL_CTX_new(3)>.
When L<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.
=head1 RETURN VALUES
The following return values can occur for SSL_CTX_set_ssl_version()
and SSL_set_ssl_method():
=over 4
=item Z<>0
The new choice failed, check the error stack to find out the reason.
=item Z<>1
The operation succeeded.
