title: Members of SSL structure
body: <p>In a OpenSSL's SSL/TLS client <a href="https://wiki.openssl.org/index.php/SSL/TLS_Client" rel="noreferrer">implementation</a>, a structure <code>SSL</code> is defined. For example here is usually the first few lines (from the link). </p>
  
  <pre><code>SSL_CTX* ctx = NULL;
  BIO *web = NULL, *out = NULL;
  SSL *ssl = NULL;
  
  init_openssl_library();
  </code></pre>
  
  <p>I have been unable to find its structure in the header files from the OpenSSL library. How can I learn the contents of <code>SSL * ssl</code>?</p>
