typedef int new_func(void *parent, void *ptr, CRYPTO_EX_DATA *ad, int idx, long argl, void *argp);
typedef void free_func(void *parent, void *ptr, CRYPTO_EX_DATA *ad, int idx, long argl, void *argp);
typedef int dup_func(CRYPTO_EX_DATA *to, CRYPTO_EX_DATA *from, void *from_d, int idx, long argl, void *argp);
DESCRIPTION
Several OpenSSL structures can have application specific data attached to them. These functions are used internally by OpenSSL to manipulate application specific data attached to a specific structure.
SSL_get_ex_new_index() is used to register a new index for application specific data.
SSL_set_ex_data() is used to store application data at arg for idx into the ssl object.
SSL_get_ex_data() is used to retrieve the information for idx from ssl.
A detailed description for the *_get_ex_new_index() functionality can be found in RSA_get_ex_new_index(3). The *_get_ex_data() and *_set_ex_data() functionality is described in CRYPTO_set_ex_data(3).
