Function Documentation

SSL_METHOD* SSL_get_ssl_method ( SSL * ssl ) ;

Returns a reference to SSL_METHOD. This structure holds pointers to functions that control operations during an SSL session. The functions are specific to particular SSL versions.
Parameters:

ssl [In] The SSL structure.

Returns:
The pointer to the SSL_METHOD for SSL.

int SSL_set_ssl_method ( SSL * ssl,

SSL_METHOD * meth

) ;

Sets the SSL method meth to override the default methods that an SSL connection inherits from its SSL_CTX when establishing the SSL connection ssl. This allows the application to support multiple SSL versions without requiring an SSL_CTX for each one.
Parameters:

ssl [In] The SSL against which to store the method.

meth [In] The new SSL_METHOD for the SSL. Stores pointers to functions that control protocol operations during an SSL session.

Returns:
1 indicates success.
0 indicates error.

The SSL_METHOD pointer.
See also:
