NAME

       SSL_CTX_get_ex_new_index, SSL_CTX_set_ex_data, SSL_CTX_get_ex_data -
       internal application specific data functions

SYNOPSIS

        #include <openssl/ssl.h>

        int SSL_CTX_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_CTX_set_ex_data(SSL_CTX *ctx, int idx, void *arg);

        void *SSL_CTX_get_ex_data(const SSL_CTX *ctx, 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_CTX_get_ex_new_index() is used to register a new index for applica-
       tion specific data.

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

       SSL_CTX_get_ex_data() is used to retrieve the information for idx from
       ctx.

       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).
