SSL_SESSION_GET_EX_NE... BSD Library Functions Manual SSL_SESSION_GET_EX_NE...

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 appli‐
     cation-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(3) (and all functions indirectly calling the dump func‐
     tions like PEM_write_SSL_SESSION(3) and PEM_write_bio_SSL_SESSION(3)) and
     can therefore not be restored.
