c++ - Ncurses后台等待退出

Question

考虑以下代码。我希望程序在按例如后结束。 F10 。我不想改变程序的行为，我想在后台做，等待按键然后结束。如何修改程序来实现这一点？

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

int main () {
      int parent_x, parent_y;
      int score_size =10;
      int counter =0 ;
      initscr();
      noecho();
      curs_set(FALSE);
      getmaxyx(stdscr, parent_y, parent_x);
      WINDOW *field = newwin(parent_y - score_size, parent_x, 0, 0);
      WINDOW *score = newwin(score_size, parent_x, parent_y - score_size, 0);
      while(true) {
          mvwprintw(field, 0, counter, "Field");
          mvwprintw(score, 0, counter, "Score");
          wrefresh(field);
          wrefresh(score);
          sleep(5);
          wclear(score);
          wclear(field);
          counter++;
      }

      delwin(field);
      delwin(score);
      endwin();
}

也许你可以在 while 循环内的某个地方读取输入

keypad(field, TRUE);
int loop = 1;
while(loop) {
  ...
  int c = wgetch(field);
  switch(c) {
    case KEY_F(10):
      loop = 0;
      break;
    default:
      break;
  }
  ...
}
