NAME

6       SSL_CTX_get_ex_data, SSL_CTX_set_ex_data, SSL_get_ex_data,
7       SSL_set_ex_data - Store and retrieve extra data from the SSL_CTX, SSL
8       or SSL_SESSION

SYNOPSIS

11        #include <openssl/ssl.h>
12
13        void *SSL_CTX_get_ex_data(const SSL_CTX *s, int idx);
14
15        int SSL_CTX_set_ex_data(SSL_CTX *s, int idx, void *arg);
16
17        void *SSL_get_ex_data(const SSL *s, int idx);
18
19        int SSL_set_ex_data(SSL *s, int idx, void *arg);

DESCRIPTION

22       SSL*_set_ex_data() functions can be used to store arbitrary user data
23       into the SSL_CTX, or SSL object. The user must supply a unique index
24       which they can subsequently use to retrieve the data using
25       SSL*_get_ex_data().
26
27       For more detailed information see CRYPTO_get_ex_data(3) and
28       CRYPTO_set_ex_data(3) which implement these functions and
29       CRYPTO_get_ex_new_index(3) for generating a unique index.
30

RETURN VALUES

32       The SSL*_set_ex_data() functions return 1 if the item is successfully
33       stored and 0 if it is not.  The SSL*_get_ex_data() functions return the
34       ex_data pointer if successful, otherwise NULL.
