Yeah, I thought a lot about using visit_start_struct purely for namespacing, but wasn't sure if that was too hackish. I like it a whole lot better than manipulating the field names though... I'll rework it and see. > > Regards, > > Anthony Liguori > > > + visit_type_int16_t(v,&tp->t_rxtcur, strocat(f, ".t_rxtcur", l),&err); > > + visit_type_int16_t(v,&tp->t_dupacks, strocat(f, ".t_dupacks", l),&err);
