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_CTX_get_ex_new_index() is used to register a new index for
34       application specific data.
35
36       SSL_CTX_set_ex_data() is used to store application data at arg for idx
37       into the ctx object.
38
39       SSL_CTX_get_ex_data() is used to retrieve the information for idx from
40       ctx.
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).
