<h1><a name="description">DESCRIPTION</a></h1>
|
||
|
<p><code>SSL_CTX_free()</code> decrements the reference count of <strong>ctx</strong>, and removes the
|
||
|
SSL_CTX object pointed to by <strong>ctx</strong> and frees up the allocated memory if the reference count has reached 0.</p>
|
||
|
<p>It also calls the free()ing procedures for indirectly affected items, if
|
||
|
applicable: the session cache, the list of ciphers, the list of Client CAs,
|
||
|
the certificates and keys.</p>
|
||
|
<p>If <strong>ctx</strong> is NULL nothing is done.</p>

<h1><a name="warnings">WARNINGS</a></h1>
|
||
|
<p>If a session-remove callback is set (SSL_CTX_sess_set_remove_cb()), this
|
||
|
callback will be called for each session being freed from <strong>ctx</strong>'s
|
||
|
session cache. This implies, that all corresponding sessions from an
|
||
|
external session cache are removed as well. If this is not desired, the user
|
||
|
should explicitly unset the callback by calling
|
||
|
SSL_CTX_sess_set_remove_cb(<strong>ctx</strong>, NULL) prior to calling <code>SSL_CTX_free()</code>.</p>
