Any code mixing the two will not work on all platforms.</p> <p> </p> <hr /> <h1><a name="return_values">RETURN VALUES</a></h1> <p><code>BIO_s_socket()</code> returns the socket BIO method.</p> <p><code>BIO_new_socket()</code> returns the newly allocated BIO or NULL is an error occurred.</p> <p> </p> <hr /> <h1><a name="copyright">COPYRIGHT</a></h1> <p>Copyright 2000-2016 The OpenSSL Project Authors.
