DESCRIPTION

29       Several OpenSSL structures can have application specific data attached
30       to them.  These functions are used internally by OpenSSL to manipulate
31       application specific data attached to a specific structure.
32
33       SSL_SESSION_get_ex_new_index() is used to register a new index for
34       application specific data.
35
36       SSL_SESSION_set_ex_data() is used to store application data at arg for
37       idx into the session object.
38
39       SSL_SESSION_get_ex_data() is used to retrieve the information for idx
40       from session.
41
42       A detailed description for the *_get_ex_new_index() functionality can
43       be found in RSA_get_ex_new_index(3).  The *_get_ex_data() and
44       *_set_ex_data() functionality is described in CRYPTO_set_ex_data(3).
45

WARNINGS

47       The application data is only maintained for sessions held in memory.
48       The application data is not included when dumping the session with
49       i2d_SSL_SESSION() (and all functions indirectly calling the dump
50       functions like PEM_write_SSL_SESSION() and PEM_write_bio_SSL_SESSION())
51       and can therefore not be restored.
