    8: =head1 SYNOPSIS
    9: 
   10:  #include <openssl/ssl.h>
   11: 
   12:  int SSL_CTX_set_ssl_version(SSL_CTX *ctx, SSL_METHOD *method);
   13:  int SSL_set_ssl_method(SSL *s, SSL_METHOD *method);
   14:  SSL_METHOD *SSL_get_ssl_method(SSL *ssl);
   15: 
   16: =head1 DESCRIPTION
   17: 
   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)|SSL_new(3)> are not affected, except when
   21: L<SSL_clear(3)|SSL_clear(3)> is being called.
   22: 
   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.
   25: 
   26: SSL_get_ssl_method() returns a function pointer to the TLS/SSL method
   27: set in B<ssl>.
   28: 
   29: =head1 NOTES
   30: 
   31: The available B<method> choices are described in
   32: L<SSL_CTX_new(3)|SSL_CTX_new(3)>.
   33: 
   34: When L<SSL_clear(3)|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.
   37: 
   38: =head1 RETURN VALUES
   39: 
   40: The following return values can occur for SSL_CTX_set_ssl_version()
   41: and SSL_set_ssl_method():

   45: =item 0
   46: 
   47: The new choice failed, check the error stack to find out the reason.
