<p>SSL_free - free an allocated SSL structure</p>

<h1><a name="description">DESCRIPTION</a></h1>
<p><code>SSL_free()</code> decrements the reference count of <strong>ssl</strong>, and removes the SSL
structure pointed to by <strong>ssl</strong> and frees up the allocated memory if the
reference count has reached 0.
If <strong>ssl</strong> is NULL nothing is done.</p>
<p>
</p>
<hr />
<h1><a name="notes">NOTES</a></h1>
<p><code>SSL_free()</code> also calls the free()ing procedures for indirectly affected items, if
applicable: the buffering BIO, the read and write BIOs,
cipher lists specially created for this <strong>ssl</strong>, the <strong>SSL_SESSION</strong>.
Do not explicitly free these indirectly freed up items before or after
calling <code>SSL_free()</code>, as trying to free things twice may lead to program
failure.</p>
<p>The ssl session has reference counts from two users: the SSL object, for
which the reference count is removed by <code>SSL_free()</code> and the internal
session cache. If the session is considered bad, because
<em>SSL_shutdown(3)</em> was not called for the connection
and <em>SSL_set_shutdown(3)</em> was not used to set the
SSL_SENT_SHUTDOWN state, the session will also be removed
from the session cache as required by <a href="http://www.ietf.org/rfc/rfc2246.txt" class="rfc">RFC2246</a>.</p>
<p>
</p>
<hr />
<h1><a name="return_values">RETURN VALUES</a></h1>
<p><code>SSL_free()</code> does not provide diagnostic information.</p>
<p><em>SSL_new(3)</em>, <em>SSL_clear(3)</em>,
<em>SSL_shutdown(3)</em>, <em>SSL_set_shutdown(3)</em>,
<em>ssl(7)</em></p>
