<h1 id="NAME">NAME</h1>

<p>SSL_get0_connection, SSL_is_connection - get a QUIC connection SSL object from a QUIC stream SSL object</p>

<h1 id="SYNOPSIS">SYNOPSIS</h1>

<pre><code>#include &lt;openssl/ssl.h&gt;

SSL *SSL_get0_connection(SSL *ssl);
int SSL_is_connection(SSL *ssl);</code></pre>

<h1 id="DESCRIPTION">DESCRIPTION</h1>

<p>The SSL_get0_connection() function, when called on a QUIC stream SSL object, returns the QUIC connection SSL object which the QUIC stream SSL object belongs to.</p>

<p>When called on a QUIC connection SSL object, it returns the same object.</p>

<p>When called on a non-QUIC object, it returns the same object it was passed.</p>

<p>SSL_is_connection() returns 1 for QUIC connection SSL objects and for non-QUIC SSL objects, but returns 0 for QUIC stream SSL objects.</p>

<h1 id="RETURN-VALUES">RETURN VALUES</h1>

<p>SSL_get0_connection() returns the QUIC connection SSL object (for a QUIC stream SSL object) and otherwise returns the same SSL object passed. It always returns non-NULL.</p>

<p>SSL_is_connection() returns 1 if the SSL object is not a QUIC stream SSL object and 0 otherwise.</p>
