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(const 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.
