<h1 id="NAME">NAME</h1>
<p>CONF_modules_free, CONF_modules_finish, CONF_modules_unload - OpenSSL configuration cleanup functions</p>
<h1 id="SYNOPSIS">SYNOPSIS</h1>
<pre><code> #include <openssl/conf.h>
void CONF_modules_finish(void);
void CONF_modules_unload(int all);</code></pre>
<p>Deprecated:</p>
<pre><code> #if OPENSSL_API_COMPAT < 0x10100000L
void CONF_modules_free(void)
#endif</code></pre>
<h1 id="DESCRIPTION">DESCRIPTION</h1>
<p>CONF_modules_free() closes down and frees up all memory allocated by all configuration modules. Normally, in versions of OpenSSL prior to 1.1.0, applications called CONF_modules_free() at exit to tidy up any configuration performed.</p>
<p>CONF_modules_finish() calls each configuration modules <b>finish</b> handler to free up any configuration that module may have performed.</p>
<p>CONF_modules_unload() finishes and unloads configuration modules. If <b>all</b> is set to <b>0</b> only modules loaded from DSOs will be unloads. If <b>all</b> is <b>1</b> all modules, including builtin modules will be unloaded.</p>
<h1 id="RETURN-VALUES">RETURN VALUES</h1>
<p>None of the functions return a value.</p>
