SSL_CTX_set_ex_data(3)              OpenSSL             SSL_CTX_set_ex_data(3)



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

LIBRARY
       libcrypto, -lcrypto

SYNOPSIS
        #include <openssl/ssl.h>

        void *SSL_CTX_get_ex_data(const SSL_CTX *s, int idx);

        int SSL_CTX_set_ex_data(SSL_CTX *s, int idx, void *arg);

        void *SSL_get_ex_data(const SSL *s, int idx);

        int SSL_set_ex_data(SSL *s, int idx, void *arg);

DESCRIPTION
       SSL*_set_ex_data() functions can be used to store arbitrary user data
       into the SSL_CTX, or SSL object. The user must supply a unique index
       which they can subsequently use to retrieve the data using
       SSL*_get_ex_data().

       For more detailed information see CRYPTO_get_ex_data(3) and
       CRYPTO_set_ex_data(3) which implement these functions and
       CRYPTO_get_ex_new_index(3) for generating a unique index.

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