NAME

SSL_CTX_get_ex_new_index, SSL_CTX_set_ex_data, SSL_CTX_get_ex_data − Internal application specific data functions

SYNOPSIS

#include <openssl/ssl.h>
int SSL_CTX_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_CTX_set_ex_data(
        SSL_CTX ∗ctx, int idx, void ∗arg ); void ∗SSL_CTX_get_ex_data(
        SSL_CTX ∗ctx, 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_CTX_get_ex_new_index() function is used to register a new index for application specific data. 

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

The SSL_CTX_get_ex_data() function is used to retrieve the information for idx from ctx. 

See RSA_get_ex_new_index() for a description of the functionality of ∗_get_ex_new_index(). The ∗_get_ex_data() and <function role="strong">∗_set_ex_data() functionality is described in CRYPTO_set_ex_data().
