the same callback handles different types of exdata.
dup_func() is called when a structure is being copied. This is only done
-for B<SSL> and B<SSL_SESSION> objects. The B<to> and B<from> parameters
+for B<SSL>, B<SSL_SESSION>, B<EC_KEY> objects and B<BIO> chains via
+BIO_dup_chain(). The B<to> and B<from> parameters
are pointers to the destination and source B<CRYPTO_EX_DATA> structures,
respectively. The B<from_d> parameter needs to be cast to a B<void **pptr>
as the API has currently the wrong signature; that will be changed in a
=head1 RETURN VALUES
-CRYPTO_get_ex_new_index() returns a new index or -1 on failure; the
-value B<0> is reserved for the legacy "app_data" API's.
+CRYPTO_get_ex_new_index() returns a new index or -1 on failure.
CRYPTO_free_ex_index() and
CRYPTO_set_ex_data() return 1 on success or 0 on failure.
