+=head1 DESCRIPTION
+
+OSSL_STORE_attach() works like L<OSSL_STORE_open(3)>, except it takes a B<BIO>
+I<bio> instead of a I<uri>, along with a I<scheme> to determine what loader
+should be used to process the data.
+
+=head1 RETURN VALUES
+
+OSSL_STORE_attach() returns a pointer to a B<OSSL_STORE_CTX> on success, or
+NULL on failure.
