This field might be used, for example, if loading the string for the error is a time-consuming operation. To use deferred fill-in, the object puts a function pointer in this slot and does not fill any of the other fields except <b>wCode</b>, which is required. To get additional information, the caller passes the <b>EXCEPINFO</b> structure back to the <b>pexcepinfo</b> callback function, which fills in the additional information. When the ActiveX object and the ActiveX client are in different processes, the ActiveX object calls <b>pfnDeferredFillIn</b> before returning to the controller.</para>
