在控制台 C++ 中获取鼠标和键盘输入

【中文标题】在控制台 C++ 中获取鼠标和键盘输入【英文标题】：Getting mouse and keyboard inputs in console C++ 【发布时间】：2011-02-14 05:32:32 【问题描述】：如何在 windows c++ 控制台应用程序中获取鼠标和键盘输入？ 我们可以注册任何回调来获取输入吗？
使用 ReadConsoleInput API 也是一个阻塞调用，所以要继续获取输入并执行后台任务，我需要使用线程。是否有任何非阻塞 APIS 来获取输入
【问题讨论】：
【参考方案1】：看起来PeekConsoleInput 是非阻塞的，所以如果你想定期轮询，你可以使用它，并且只有在你知道有可用输入之后才调用 ReadConsoleInput。 还有GetNumberOfConsoleInputEvents。
【讨论】：
【参考方案2】：还有GetAsyncKeyState，既可以用于键盘也可以用于鼠标。
【讨论】：
【参考方案3】：使用控制台自己的键盘和鼠标事件处理程序 - ReadConsoleInput( )
