OSSL_FUNC_store_close() frees the provider side context I<ctx>.
+When a provider-native object is created by a store manager it would be unsuitable
+for direct use with a foreign provider. The export function allows for
+exporting the object to that foreign provider if the foreign provider
+supports the type of the object and provides an import function.
+
+OSSL_FUNC_store_export_object() should export the object of size I<objref_sz>
+referenced by I<objref> as an B<OSSL_PARAM> array and pass that to the
+I<export_cb> as well as the given I<export_cbarg>.
