NAME

SSL_SESSION_get_ex_new_index, SSL_SESSION_set_ex_data, SSL_SESSION_get_ex_data − internal application specific data functions

SYNOPSIS

 #include <openssl/ssl.h>
 int SSL_SESSION_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_SESSION_set_ex_data(SSL_SESSION *session, int idx, void *arg);
 void *SSL_SESSION_get_ex_data(SSL_SESSION *session, 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_SESSION_get_ex_new_index() is used to register a new index for application specific data.

SSL_SESSION_set_ex_data() is used to store application data at arg for idx into the session object.

SSL_SESSION_get_ex_data() is used to retrieve the information for idx from session.

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).

WARNINGS

The application data is only maintained for sessions held in memory. The application data is not included when dumping the session with i2d_SSL_SESSION() (and all functions indirectly calling the dump functions like PEM_write_SSL_SESSION() and PEM_write_bio_SSL_SESSION()) and can therefore not be restored.
