35 In the description here, I<TYPE> is used a placeholder
36 for any of the OpenSSL datatypes listed in
37 L<CRYPTO_get_ex_new_index(3)>.
39 These functions handle application-specific data for OpenSSL data
42 TYPE_get_ex_new_index() is a macro that calls CRYPTO_get_ex_new_index()
43 with the correct B<index> value.
45 TYPE_set_ex_data() is a function that calls CRYPTO_set_ex_data() with
46 an offset into the opaque exdata part of the TYPE object.
48 TYPE_get_ex_data() is a function that calls CRYPTO_get_ex_data() with
49 an offset into the opaque exdata part of the TYPE object.
53 TYPE_get_ex_new_index() returns a new index on success or -1 on error.
55 TYPE_set_ex_data() returns 1 on success or 0 on error.
57 TYPE_get_ex_data() returns the application data or NULL if an error occurred.
