I<d> B<MUST NOT> be NULL. 93 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. I<d> B<MUST NOT> be NULL. 96 97 For compatibility with previous releases, the exdata index of zero is 98 reserved for "application data." There are two convenience functions for 99 this. 100 TYPE_set_app_data() is a macro that invokes TYPE_set_ex_data() with 101 B<idx> set to zero. 102 TYPE_get_app_data() is a macro that invokes TYPE_get_ex_data() with 103 B<idx> set to zero. 104 105 =head1 RETURN VALUES 106 107 TYPE_get_ex_new_index() returns a new index on success or -1 on error. 108 109 TYPE_set_ex_data() returns 1 on success or 0 on error. 110 111 TYPE_get_ex_data() returns the application data or NULL if an error occurred. 112 113 =head1 SEE ALSO 114 115 L<CRYPTO_get_ex_new_index(3)>. 116 117 =head1 HISTORY 118 119 The functions DH_get_ex_new_index(), DH_set_ex_data(), DH_get_ex_data(), 120 DSA_get_ex_new_index(), DSA_set_ex_data(), DSA_get_ex_data(), 121 EC_KEY_get_ex_new_index(), EC_KEY_set_ex_data(), EC_KEY_get_ex_data(), 122 ENGINE_get_ex_new_index(), ENGINE_set_ex_data(), ENGINE_get_ex_data(), 123 RSA_get_ex_new_index(), RSA_set_ex_data(), RSA_get_ex_data(), 124 RSA_set_app_data() and RSA_get_app_data() were deprecated in OpenSSL 3.0. 125 126 =head1 COPYRIGHT 127 128 Copyright 2015-2021 The OpenSSL Project Authors.
