Yes, returning-structure is a bad design in most case, but we can't change mallinfo prototype since it is defined by other OS: http://man7.org/linux/man-pages/man3/mallinfo.3.html > my feeling is the opposite. > after all, it's a matter of taste i guess. > I mean the code contained #ifdef/#endif is more uglier than other. there are many place conditioned by CAN_PASS_STRUCTS, mallinfo is just one of case. It's better to fix all places instead. > On Thu, Mar 19, 2020 at 7:22 PM Xiang Xiao <xiaoxiang781...@gmail.com> wrote: > > > > But, should we support the aged compiler to make the code ugly?
