在Linux C ++上检测keydown和keyup事件 [英] Detecting keydown and keyup events on Linux C++

问题描述

可能重复：

在C中访问按键

监控键盘上的键盘Ubuntu

我想检测和时间戳每个keydown和keyup事件程序（是，我的意思是键下和键upup 而不仅仅是按键）以及按下什么键。我可以通过使用一个APi如GTK，但我想尽可能简单和低级别，以避免从库影响时间和编写较少的代码的开销。

I want to detect and time stamp every keydown and keyup event in a program (Yes, I mean keydown and keyup not just keypress) along with what key was pressed. I could do this by using an APi such as GTK, but I want to get as simple and low level as possible in order to avoid overhead from the libraries affecting the times as well as writing less code.

我已经搜索了一段时间了，到目前为止已经发现了大量的东西，如何在Windows上做，这不帮助我，因为我使用的是Linux系统，以及如何检测

I have been googling this for a while and so far have found a ton of stuff about how to do it on Windows, which doesn't help me since I am using a Linux system, and how to detect a key press on Linux, but not keyup keydown.

任何人都可以告诉我什么系统调用，库等等，我需要使用以捕获keydown和keyup事件在Linux系统上用C ++的命令行程序？

Can anyone tell me what syscall, library, etc. I would need to use in order to capture the keydown and keyup events on a Linux system with a commandline program in C++? And if you have a link to a tutorial or a code example it would be most appreciated.

推荐答案

实际上，你不是将能够做到这一点没有图书馆。如果您需要的开销很小，我建议您 ncurses 。如果你绝对必须做没有库，看看ncurses如何实现它。这当然会非常复杂。

Realistically, you aren't going to be able to do this without a library. If you want something that has very little overhead, I would suggest ncurses. If you absolutely must do it without a library, look at how ncurses implements it. It will, of course, be very complicated.
