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).
