SYNOPSIS
     #include <openssl/x509.h>

     int
     TYPE_get_ex_new_index(long argl, void *argp, CRYPTO_EX_new *new_func,
	 CRYPTO_EX_dup *dup_func, CRYPTO_EX_free *free_func);

     int
     TYPE_set_ex_data(TYPE *d, int idx, void *arg);

     void *
     TYPE_get_ex_data(TYPE *d, int idx);

DESCRIPTION
     In the description here, TYPE is used a placeholder for any of the
     OpenSSL datatypes listed in CRYPTO_get_ex_new_index(3).

     These functions handle application-specific data for OpenSSL data struc-
     tures.

     TYPE_get_ex_new_index() is a macro that calls CRYPTO_get_ex_new_index(3)
     with the correct index value.

     TYPE_set_ex_data() is a function that calls CRYPTO_set_ex_data(3) with an
     offset into the opaque exdata part of the TYPE object.

     TYPE_get_ex_data() is a function that calls CRYPTO_get_ex_data(3) with an
     offset into the opaque exdata part of the TYPE object.

RETURN VALUES
     TYPE_get_new_ex_index() returns a new index on success or -1 on error.

     TYPE_set_ex_data() returns 1 on success or 0 on error.

     TYPE_get_ex_data() returns the application data or NULL if an error
     occurred.
