---------------------------------------------------------------------- (0003789) Clausecker (reporter) - 2017-06-19 18:43 http://austingroupbugs.net/view.php?id=1151#c3789 ---------------------------------------------------------------------- struct winsize is the historic name for this structure, used since at least 1989. Renaming it might cause more problems than it solves. Note that tcsetsize and tcgetsize aren't reserved by POSIX either (probably by mistake). Mandating unsigned long as the type for the members is a bad idea as this contradicts existing implementations. All implementations I checked use unsigned short for this type. As I already mentioned, introducing a typedef windim_t might be a good compromise between compatibility and future expansions. I don't see how adding ENOTSUP might be a good idea. If the terminal's size cannot be changed, an implementation may either decide to make size changes have no effect (this might be a good idea for serial ports where the device driver cannot change the terminal but e.g. login(8) might want to set up the window size with information from the termcap database) or decide that each other possible terminal size is invalid, returning EINVAL. Changing the terminal size to itself should never cause an error, even on a fixed-size terminal. Perhaps that invariant should be specified, too.
