<h1 id="NAME">NAME</h1>

<p>SSL_rstate_string, SSL_rstate_string_long - get textual description of state of an SSL object during read operation</p>

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

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

const char *SSL_rstate_string(SSL *ssl);
const char *SSL_rstate_string_long(SSL *ssl);</code></pre>

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

<p>SSL_rstate_string() returns a 2 letter string indicating the current read state of the SSL object <b>ssl</b>.</p>

<p>SSL_rstate_string_long() returns a string indicating the current read state of the SSL object <b>ssl</b>.</p>

<h1 id="NOTES">NOTES</h1>

<p>When performing a read operation, the SSL/TLS engine must parse the record, consisting of header and body. When working in a blocking environment, SSL_rstate_string[_long]() should always return &quot;RD&quot;/&quot;read done&quot;.</p>

<p>This function should only seldom be needed in applications.</p>

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

<p>SSL_rstate_string() and SSL_rstate_string_long() can return the following values:</p>

<dl>

<dt id="RH-read-header">&quot;RH&quot;/&quot;read header&quot;</dt>
<dd>

<p>The header of the record is being evaluated.</p>

</dd>
<dt id="RB-read-body">&quot;RB&quot;/&quot;read body&quot;</dt>
<dd>

<p>The body of the record is being evaluated.</p>

</dd>
<dt id="unknown-unknown">&quot;unknown&quot;/&quot;unknown&quot;</dt>
<dd>

<p>The read state is unknown. This should never happen.</p>

</dd>
</dl>

<p>When used with QUIC SSL objects, these functions always return &quot;RH&quot;/&quot;read header&quot; in normal conditions.</p>
