<p>SSL_group_to_name - get name of group</p>

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

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

const char *SSL_group_to_name(SSL *ssl, int id);</code></pre>

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

<p>SSL_group_to_name() is used to retrieve the TLS group name associated with a given TLS group ID, as registered via built-in or external providers and as returned by a call to SSL_get1_groups() or SSL_get_shared_group().</p>

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

<p>If non-NULL, SSL_group_to_name() returns the TLS group name corresponding to the given <i>id</i> as a NUL-terminated string. If SSL_group_to_name() returns NULL, an error occurred; possibly no corresponding tlsname was registered during provider initialisation.</p>

<p>Note that the return value is valid only during the lifetime of the SSL object <i>ssl</i>.</p>
