<p>d2i_SSL_SESSION, i2d_SSL_SESSION - convert SSL_SESSION object from/to ASN1 representation</p>
<p>
</p>
<hr />
<h1><a name="synopsis">SYNOPSIS</a></h1>
<pre>
#include <openssl/ssl.h></pre>
<pre>
SSL_SESSION *d2i_SSL_SESSION(SSL_SESSION **a, const unsigned char **pp,
long length);
int i2d_SSL_SESSION(SSL_SESSION *in, unsigned char **pp);</pre>
<p>

<h1><a name="description">DESCRIPTION</a></h1>
<p>These functions decode and encode an SSL_SESSION object.
For encoding details see <em>d2i_X509(3)</em>.</p>
<p>SSL_SESSION objects keep internal link information about the session cache
list, when being inserted into one SSL_CTX object's session cache.
One SSL_SESSION object, regardless of its reference count, must therefore
only be used with one SSL_CTX object (and the SSL objects created
from this SSL_CTX object).</p>
<p>
</p>
<hr />
<h1><a name="return_values">RETURN VALUES</a></h1>
<p>d2i_SSL_SESSION() returns a pointer to the newly allocated SSL_SESSION
object. In case of failure the NULL-pointer is returned and the error message
can be retrieved from the error stack.</p>
<p>i2d_SSL_SESSION() returns the size of the ASN1 representation in bytes.
When the session is not valid, <strong>0</strong> is returned and no operation is performed.</p>
