好的,所以我最初一直在尝试使用一些据称仅适用于 Windows 的标头,我的错,但我已经走了,只是使用 curses.h 复制了我需要的东西。但是我仍然收到完全相同的错误。

所以,我不能 100% 确定代码是否应该像我期望的那样工作。我只是想编译它来测试它。根据 curses.h 文档,如果没有键排队,getch 应该返回值 ERR。我真的不知道这里还需要什么,我认为我需要做的就是包含定义所在的标题。但这似乎还不够,我一定错过了一些东西。这是我要编译的简短测试
#include <cstdlib>
#include <iostream>
#include <curses.h>
#include <ncurses.h>
using namespace std;
bool kbhit()
{
int ch = getch();
if(ch != ERR)
{
ungetch(ch);
return true;
}
return false;
}
int main() {
while(!kbhit())
{
cout << "no input";
}
cout << "Mummy, it's over.";
return 0;
}
