SSL_GET_EX_NEW_INDE... FreeBSD Library Functions Manual	SSL_GET_EX_NEW_INDE...

NAME
     SSL_get_ex_new_index, SSL_set_ex_data, SSL_get_ex_data -- internal	appli-
     cation specific data functions

SYNOPSIS
     #include <openssl/ssl.h>

     int
     SSL_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_set_ex_data(SSL *ssl, int idx,	void *arg);

     void *
     SSL_get_ex_data(const SSL *ssl, 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 ap-
     plication specific	data attached to a specific structure.

     SSL_get_ex_new_index() is used to register	a new index for	application
     specific data.

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

     SSL_get_ex_data() is used to retrieve the information for idx from	ssl.

     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).

EXAMPLES
     An	example	of how to use the functionality	is included in the example
     verify_callback() in SSL_CTX_set_verify(3).

SEE ALSO
     CRYPTO_set_ex_data(3), RSA_get_ex_new_index(3), ssl(3),
     SSL_CTX_set_verify(3)

HISTORY
     Precursor functions SSL_set_app_data() and	SSL_get_app_data() first ap-
     peared in SSLeay 0.6.1.

     SSL_get_ex_new_index(), SSL_set_ex_data(),	and SSL_get_ex_data() first
     appeared in SSLeay	0.9.0 and have been available since OpenBSD 2.4.
