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.
