1=pod 2 3=head1 NAME 4 5d2i_SSL_SESSION, i2d_SSL_SESSION - convert SSL_SESSION object from/to ASN1 representation 6 7=head1 SYNOPSIS 8 9 #include <openssl/ssl.h> 10 11 SSL_SESSION *d2i_SSL_SESSION(SSL_SESSION **a, const unsigned char **pp, 12 long length); 13 int i2d_SSL_SESSION(SSL_SESSION *in, unsigned char **pp); 14 15=head1 DESCRIPTION 16 17These functions decode and encode an SSL_SESSION object. 18For encoding details see L<d2i_X509(3)>. 19 20SSL_SESSION objects keep internal link information about the session cache 21list, when being inserted into one SSL_CTX object's session cache. 22One SSL_SESSION object, regardless of its reference count, must therefore 23only be used with one SSL_CTX object (and the SSL objects created 24from this SSL_CTX object). 25 26=head1 RETURN VALUES 27 28d2i_SSL_SESSION() returns a pointer to the newly allocated SSL_SESSION 29object. In case of failure the NULL-pointer is returned and the error message 30can be retrieved from the error stack. 31 32i2d_SSL_SESSION() returns the size of the ASN1 representation in bytes. 33When the session is not valid, B<0> is returned and no operation is performed. 34 35=head1 SEE ALSO 36 37L<ssl(7)>, L<SSL_SESSION_free(3)>, 38L<SSL_CTX_sess_set_get_cb(3)>, 39L<d2i_X509(3)> 40 41=head1 COPYRIGHT 42 43Copyright 2001-2016 The OpenSSL Project Authors.
