     NAME
          SSL_get_ex_new_index, SSL_set_ex_data, SSL_get_ex_data -
          internal application 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(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 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 *_ggeett_eexx_nneeww_iinnddeexx(())
          functionality can be found in RSA_get_ex_new_index(3).  The
          *_ggeett_eexx_ddaattaa(()) and *_sseett_eexx_ddaattaa(()) functionality is
          described in CRYPTO_set_ex_data(3).

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