ncurses在后台？

如何解决ncurses在后台？

为什么ncurses在后台不起作用？

#include <iostream>
#include <ctime>
#include <unistd.h>
#include <ncurses.h>

int main () {
    setlocale(LC_ALL,"");
    while (true) {
        time_t seconds = time(nullptr);
        tm* timeinfo = localtime(&seconds);
        if (timeinfo->tm_hour >= 23 || timeinfo->tm_hour <= 3) {
            unsigned wait = 15 * 60;

            initscr(); cbreak(); noecho();
            printw("Go to bed,pls)\n");
            printw("Press enter:");
            int ch = getch();
            while (ch == 410) {
                ch = getch();
            }
            endwin();

            sleep(wait);
            continue;
        }
        unsigned wait = (23 - timeinfo->tm_hour) * 3600 - (60 - timeinfo->tm_min) * 60 - timeinfo->tm_sec;
        sleep(wait);
    }
}

但是当我在后台（./a.out＆）中运行此代码时，我看不到ncurses窗口。可以解决这个问题吗？
