<p>SSL_CTX_sessions - access internal session cache</p>

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

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

LHASH_OF(SSL_SESSION) *SSL_CTX_sessions(SSL_CTX *ctx);</code></pre>

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

<p>SSL_CTX_sessions() returns a pointer to the lhash databases containing the internal session cache for <b>ctx</b>.</p>

<h1 id="NOTES">NOTES</h1>

<p>The sessions in the internal session cache are kept in an <a href="../man3/LHASH.html">LHASH(3)</a> type database. It is possible to directly access this database e.g. for searching. In parallel, the sessions form a linked list which is maintained separately from the <a href="../man3/LHASH.html">LHASH(3)</a> operations, so that the database must not be modified directly but by using the <a href="../man3/SSL_CTX_add_session.html">SSL_CTX_add_session(3)</a> family of functions.</p>

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

<p>SSL_CTX_sessions() returns a pointer to the lhash of <b>SSL_SESSION</b>.</p>
