I have much code writing using something like this: HB_FUNC (TEST) ( some *pPtr;
if (! ISPOINTER (1)) return; pPtr = (add *) hb_parptr (1); ... more code here ) As I understand it then from now on the right would add a further validation as: HB_FUNC (TEST) ( some *pPtr; if (! ISPOINTER (1)) return; pPtr = (add *) hb_parptr (1); if (! pPtr) return; ... more code here ) Brgds, Vailton Renato _______________________________________________ Harbour mailing list Harbour@harbour-project.org http://lists.harbour-project.org/mailman/listinfo/harbour
