There was recently an instance where a user was confused by the deprecation warnings in the docs. They believed the warning applied to the immediately preceding function declarations, when it fact it applied to the following function declarations. https://mta.openssl.org/pipermail/openssl-users/2021-December/014665.html We clarify the wording to make it clear that the warning applies to the following functions.

=head1 DESCRIPTION
|
|
|
|
In the description here, I<TYPE> is used a placeholder
|
|
for any of the OpenSSL datatypes listed in L<CRYPTO_get_ex_new_index(3)>.
|
|
|
|
All functions with a I<TYPE> of B<DH>, B<DSA>, B<RSA> and B<EC_KEY> are deprecated.
|
|
Applications should instead use EVP_PKEY_set_ex_data(),
|
|
EVP_PKEY_get_ex_data() and EVP_PKEY_get_ex_new_index().
|
|
|
|
All functions with a I<TYPE> of B<ENGINE> are deprecated.
|
|
Applications using engines should be replaced by providers.
|
|
|
|
These functions handle application-specific data for OpenSSL data
|
|
structures.
|
|
|
|
TYPE_get_ex_new_index() is a macro that calls CRYPTO_get_ex_new_index()
|
|
with the correct B<index> value.
|
|
|
|
TYPE_set_ex_data() is a function that calls CRYPTO_set_ex_data() 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() with
|
|
an offset into the opaque exdata part of the TYPE object.
|
|
|
|
For compatibility with previous releases, the exdata index of zero is
|
|
reserved for "application data." There are two convenience functions for
|
|
this.
|
|
TYPE_set_app_data() is a macro that invokes TYPE_set_ex_data() with
|
|
B<idx> set to zero.
|
|
TYPE_get_app_data() is a macro that invokes TYPE_get_ex_data() with
|
|
B<idx> set to zero.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
TYPE_get_ex_new_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.
|
|
|
|
=head1 SEE ALSO
|
|
|
|
