Hi, Viktor.

You full code from wiki is:

        const char *servername;
        SSL *ssl;
        X509_VERIFY_PARAM *param;

        servername = "www.example.com";
        ssl = SSL_new(...);
        param = SSL_get0_param(ssl);

        /* Enable automatic hostname checks */
        X509_VERIFY_PARAM_set_hostflags(param, 
X509_CHECK_FLAG_NO_PARTIAL_WILDCARDS);
        X509_VERIFY_PARAM_set1_host(param, servername, 0);

        /* Configure a non-zero callback if desired */
        SSL_set_verify(ssl, SSL_VERIFY_PEER, 0);

        /*
         * Establish SSL connection, hostname should be checked
         * automatically test with a hostname that should not match,
         * the connection will fail (unless you specify a callback
         * that returns despite the verification failure.  In that
         * case SSL_get_verify_status() can expose the problem after
         * connection completion.
         */
         ...

You set here only "param":
        X509_VERIFY_PARAM_set_hostflags(param, 
X509_CHECK_FLAG_NO_PARTIAL_WILDCARDS);
        X509_VERIFY_PARAM_set1_host(param, servername, 0);

But how this variable is associated with "ssl" object or "ctx" object?
I don't understand really! Please explain more in detail.

I know this function only SSL_CTX_set1_param() that associates "param"  with 
context "ctx".
