75 In the description here, I<TYPE> is used a placeholder
76 for any of the OpenSSL datatypes listed in L<CRYPTO_get_ex_new_index(3)>.
78 All functions with a I<TYPE> of B<DH>, B<DSA>, B<RSA> and B<EC_KEY> are deprecated.
79 Applications should instead use EVP_PKEY_set_ex_data(),
80 EVP_PKEY_get_ex_data() and EVP_PKEY_get_ex_new_index().
82 All functions with a I<TYPE> of B<ENGINE> are deprecated.
83 Applications using engines should be replaced by providers.
85 These functions handle application-specific data for OpenSSL data
88 TYPE_get_ex_new_index() is a macro that calls CRYPTO_get_ex_new_index()
89 with the correct B<index> value.
91 TYPE_set_ex_data() is a function that calls CRYPTO_set_ex_data() with
92 an offset into the opaque exdata part of the TYPE object.
94 TYPE_get_ex_data() is a function that calls CRYPTO_get_ex_data() with
95 an offset into the opaque exdata part of the TYPE object.
97 For compatibility with previous releases, the exdata index of zero is
98 reserved for "application data." There are two convenience functions for
100 TYPE_set_app_data() is a macro that invokes TYPE_set_ex_data() with
102 TYPE_get_app_data() is a macro that invokes TYPE_get_ex_data() with
107 TYPE_get_ex_new_index() returns a new index on success or -1 on error.
109 TYPE_set_ex_data() returns 1 on success or 0 on error.
111 TYPE_get_ex_data() returns the application data or NULL if an error occurred.
