=head1 NAME

d2i_SSL_SESSION, i2d_SSL_SESSION - convert SSL_SESSION object from/to ASN1 representation

=head1 SYNOPSIS

 #include <openssl/ssl.h>

 SSL_SESSION *d2i_SSL_SESSION(SSL_SESSION **a, const unsigned char **pp,
                              long length);
 int i2d_SSL_SESSION(SSL_SESSION *in, unsigned char **pp);

=head1 DESCRIPTION

These functions decode and encode an SSL_SESSION object.
For encoding details see L<d2i_X509(3)>.

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).

=head1 RETURN VALUES

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.

i2d_SSL_SESSION() returns the size of the ASN1 representation in bytes.
When the session is not valid, B<0> is returned and no operation is performed.
