<h1><a name="description">DESCRIPTION</a></h1>
|
|
<p><code>SSL_set_fd()</code> sets the file descriptor <strong>fd</strong> as the input/output facility
|
|
for the TLS/SSL (encrypted) side of <strong>ssl</strong>. <strong>fd</strong> will typically be the
|
|
socket file descriptor of a network connection.</p>
|
|
<p>When performing the operation, a <strong>socket BIO</strong> is automatically created to
|
|
interface between the <strong>ssl</strong> and <strong>fd</strong>. The BIO and hence the SSL engine
|
|
inherit the behaviour of <strong>fd</strong>. If <strong>fd</strong> is non-blocking, the <strong>ssl</strong> will
|
|
also have non-blocking behaviour.</p>
|
|
<p>If there was already a BIO connected to <strong>ssl</strong>, <code>BIO_free()</code> will be called
|
|
(for both the reading and writing side, if different).</p>
|
|
<p><code>SSL_set_rfd()</code> and <code>SSL_set_wfd()</code> perform the respective action, but only
|
|
for the read channel or the write channel, which can be set independently.</p>
