=pod =head1 NAME d2i_SSL_SESSION, i2d_SSL_SESSION - convert SSL_SESSION object from/to ASN1 representation =head1 SYNOPSIS #include 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. 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. =head1 SEE ALSO L, L, L, L =head1 COPYRIGHT Copyright 2001-2016 The OpenSSL Project Authors. All Rights Reserved.
