49 In the description here, I<TYPE> is used a placeholder
50 for any of the OpenSSL datatypes listed in
51 L<CRYPTO_get_ex_new_index(3)>.
53 These functions handle application-specific data for OpenSSL data
56 TYPE_get_ex_new_index() is a macro that calls CRYPTO_get_ex_new_index()
57 with the correct B<index> value.
59 TYPE_set_ex_data() is a function that calls CRYPTO_set_ex_data() with
60 an offset into the opaque exdata part of the TYPE object.
62 TYPE_get_ex_data() is a function that calls CRYPTO_get_ex_data() with
63 an offset into the opaque exdata part of the TYPE object.
65 For compatibility with previous releases, the exdata index of zero is
66 reserved for "application data." There are two convenience functions for
68 TYPE_set_app_data() is a macro that invokes TYPE_set_ex_data() with
70 TYPE_get_app_data() is a macro that invokes TYPE_get_ex_data() with
72 Note that these functions are not defined for the B<RAND_DRBG> type because
73 there are no backward compatibility concerns.
77 TYPE_get_ex_new_index() returns a new index on success or -1 on error.
79 TYPE_set_ex_data() returns 1 on success or 0 on error.
81 TYPE_get_ex_data() returns the application data or NULL if an error occurred.
