               long argl, void  *argp,  CRYPTO_EX_new  *new_func,

       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

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.

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

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

       The SSL_get_ex_data() function 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 of the functionality is included  in  the  verify_callback()
  function example in SSL_CTX_set_verify(3).
