SSL_get_ex_new_index(3) OpenSSL SSL_get_ex_new_index(3)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(const 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.
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).
EXAMPLES
An example on how to use the functionality is included in the example
verify_callback() in SSL_CTX_set_verify(3).
