SYNOPSIS    [Toc]    [Back]

        #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(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    [Toc]    [Back]

       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_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    [Toc]    [Back]

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