const unsigned char *SSL_SESSION_get0_id_context(const SSL_SESSION *s,

<h1><a name="description">DESCRIPTION</a></h1>
<p>See <em>SSL_CTX_set_session_id_context(3)</em> for further details on session ID
contexts.</p>
<p>SSL_SESSION_get0_id_context() returns the ID context associated with
the SSL/TLS session <strong>s</strong>. The length of the ID context is written to
<strong>*len</strong> if <strong>len</strong> is not NULL.</p>
<p>The value returned is a pointer to an object maintained within <strong>s</strong> and
should not be released.</p>
<p>SSL_SESSION_set1_id_context() takes a copy of the provided ID context given in
<strong>sid_ctx</strong> and associates it with the session <strong>s</strong>. The length of the ID context
is given by <strong>sid_ctx_len</strong> which must not exceed SSL_MAX_SID_CTX_LENGTH bytes.</p>
<p>
</p>

<h1><a name="return_values">RETURN VALUES</a></h1>
<p>SSL_SESSION_set1_id_context() returns 1 on success or 0 on error.</p>
