Actually i think there was lots of discussion of this for the 2024 version, and it says For all other error situations (except for [EBADF] where fildes was invalid), fildes shall be closed. It only remains EINTR / POSIX_CLOSE_RESTART as a problem. That is being defined as POSIX_CLOSE_RESTART Allows restarts if a signal interrupts a close operation. This constant shall not be 0 unless posix_close( ) never returns −1 with errno set to [EINTR]. |accommodate some buggy ancient proprietary Unix).
