SSL_SESSION_get_ex_new_index(3)	    OpenSSL    SSL_SESSION_get_ex_new_index(3)

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.
