如何在结构中保存ncurses窗口？

struct Window {
    WINDOW* win;
    int x;
    int y;
    int width;
    int height;
    char* title;
};

struct Window createWindow(int x, int y, int width, int height, char* title) {
    struct Window window;
    window.win = newwin(height, width, y, x);
    window.x = x;
    window.y = y;
    window.width = width;
    window.height = height;
    window.title = title;
    return window;
}

struct Window window = createWindow(10, 10, 20, 10, "My Window");
mvwprintw(window.win, 1, 1, "Hello, World!");
wrefresh(window.win);
