Linux / Windows 上面 C++ 获取控制台窗口缓冲大小

Windows 通过WINAPI；GetConsoleScreenBufferInfo 实现

Linux 通过CAPI：ioctl(...,?TIOCGWINSZ...) 实现

    bool GetConsoleWindowSize(int& x, int& y) noexcept {
        x = 0;
        y = 0;

#ifdef _WIN32
        HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE);
        if (NULL == hConsole) {
            return false;
        }

        CONSOLE_SCREEN_BUFFER_INFO csbi;
        if (!::GetConsoleScreenBufferInfo(hConsole, &csbi)) {
            return false;
        }

        y = csbi.srWindow.Bottom - csbi.srWindow.Top + 1;
        x = csbi.srWindow.Right - csbi.srWindow.Left + 1;
#else
        struct winsize w;
        if (ioctl(STDOUT_FILENO, TIOCGWINSZ, &w) == -1) {
            return false;
        }

        x = w.ws_row;
        y = w.ws_col;
#endif
        return true;
    }
