=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)>.
|
|
|
|
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 HISTORY
|
|
|
|

|
|
functions were deprecated in OpenSSL 3.0.
