控制台键盘命中检测和解释 [英] Console Keyboard hit detection and interpretting

问题描述

嘿，所以它被推荐给我，我应该使用kdhit（）函数来检测控制台窗口中的按键：

Hey so it's been reccomended to me that i should use the kdhit() function to detect a keypress in a console window:

如果是Windows，kbhit （）函数是你想要的家伙，如果是* nix，这里是一个kbhit（）模拟器kbhit（）立即返回一个标志，说有没有一个键盘字符等待被读取可以测试该标志，看看是否应该发出键盘读取。

"If it's Windows, the kbhit( ) function is the guy you want. If it's *nix, here's a kbhit( ) emulator. kbhit( ) returns immediately (no blocking) with a flag that says that there is or is not a keyboard character waiting to be read. You can test the flag to see if you should issue a keyboard read."

然而，我想知道最简单，希望标准的读取键缓冲区的方式，调用标志。任何提示？ 谢谢！

However i would like to know the easiest, hopefully standard way of reading the key buffer or what he calls the flag. Any tips? Thanks!

推荐答案

使用_kbhit（）测试是否按下某个键。和当它使用_getch（）来获取值。 （注意_getch（）可以为特殊键返回0或0xE0，并为该值再次调用_getch（）。
用于在使用_getche（）时显示字符。

Use _kbhit() to test if a key is pressed. and when it is use _getch() to get the value. (note _getch() can return 0 or 0xE0 for special keys and call _getch() again for that value) for displaying the characters while reading use _getche().
