NAME

SSL_get_ex_new_index, SSL_set_ex_data, SSL_get_ex_data − Internal application specific data functions

SYNOPSIS

#include <openssl/ssl.h>
int SSL_get_ex_new_index(
        long argl, void ∗argp, CRYPTO_EX_new ∗new_func,                  CRYPTO_EX_dup ∗dup_func, CRYPTO_EX_free ∗free_func ); int SSL_set_ex_data(
        SSL ∗ssl, int idx, void ∗arg ); void ∗SSL_get_ex_data(
        SSL ∗ssl, int idx ); 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. 

The SSL_get_ex_new_index() function is used to register a new index for application specific data. 

The SSL_set_ex_data() function is used to store application data at arg for idx into the ssl object. 

The SSL_get_ex_data() function 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). 

EXAMPLES

An example of the functionality is included in the verify_callback() function example in SSL_CTX_set_verify(3).
