22                       int idx, long argl, void *argp);
23        typedef void free_func(void *parent, void *ptr, CRYPTO_EX_DATA *ad,

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_get_ex_new_index() is used to register a new index for application
34       specific data.
35
36       SSL_set_ex_data() is used to store application data at arg for idx into
37       the ssl object.
38
39       SSL_get_ex_data() is used to retrieve the information for idx from ssl.
40
41       A detailed description for the *_get_ex_new_index() functionality can
42       be found in RSA_get_ex_new_index(3).  The *_get_ex_data() and
43       *_set_ex_data() functionality is described in CRYPTO_set_ex_data(3).
44

EXAMPLES

46       An example on how to use the functionality is included in the example
47       verify_callback() in SSL_CTX_set_verify(3).
