- DH * DSA_dup_DH(const DSA *r);
+The following functions have been deprecated since OpenSSL 3.0, and can be
+hidden entirely by defining B<OPENSSL_API_COMPAT> with a suitable version value,
+see L<openssl_user_macros(7)>:
+
+ DH *DSA_dup_DH(const DSA *r);
=head1 DESCRIPTION
+The function described on this page is deprecated. There is no direct
+replacement, applications should use the EVP_PKEY APIs for Diffie-Hellman
+operations.
+
DSA_dup_DH() duplicates DSA parameters/keys as DH parameters/keys. q
is lost during that conversion, but the resulting DH parameters
contain its length.
-=head1 RETURN VALUE
+=head1 RETURN VALUES
DSA_dup_DH() returns the new B<DH> structure, and NULL on error. The
error codes can be obtained by L<ERR_get_error(3)>.
