29 Several OpenSSL structures can have application specific data attached to them.
30 These functions are used internally by OpenSSL to manipulate application
31 specific data attached to a specific structure.
33 SSL_SESSION_get_ex_new_index() is used to register a new index for application
36 SSL_SESSION_set_ex_data() is used to store application data at B<arg> for B<idx>
37 into the B<session> object.
39 SSL_SESSION_get_ex_data() is used to retrieve the information for B<idx> from
42 A detailed description for the B<*_get_ex_new_index()> functionality
43 can be found in L<RSA_get_ex_new_index(3)|RSA_get_ex_new_index(3)>.
44 The B<*_get_ex_data()> and B<*_set_ex_data()> functionality is described in
45 L<CRYPTO_set_ex_data(3)|CRYPTO_set_ex_data(3)>.
49 The application data is only maintained for sessions held in memory. The
50 application data is not included when dumping the session with
51 i2d_SSL_SESSION() (and all functions indirectly calling the dump functions
52 like PEM_write_SSL_SESSION() and PEM_write_bio_SSL_SESSION()) and can
53 therefore not be restored.
