推荐答案

正确的答案被多么惊人有时降级，并回答说：权威性放弃升职......随着创造力位，KEY_NAME实际持有权关键弄清这一点，只有一条 - 那SHIFT / ALT / CTRL是在同一时间与其他键pssed $ p $：

Amazing how sometimes the right answer gets demoted, and answers that "authoritatively" give up get promoted... With a bit of creativity, key_name actually holds the right key to figuring this out, with one caveat - that SHIFT/ALT/CTRL are pressed with other keys at the same time:

• 首先，对于普通键，如打印的人，你可以很容易地检测转变，因为它uppercases。

• First, for "normal keys" such as the printable ones, you can easily detect shift because it uppercases.

有关特殊键，例如KEY_LEFT，你会看到，当SHIFT选择实际上是KEY_SLEFT产生的code。同上，用于KEY_RIGHT。不幸的是，没有这样的运气KEY_UP / KEY_DOWN，它通过SHIFT似乎未受影响。所以，你可以通过函数getch（）返回的字符区分 - 在KEY_S ..意味着转变是pressed

For special keys, e.g. KEY_LEFT, you will see that the code generated when SHIFT is selected is actually KEY_SLEFT. ditto for KEY_RIGHT. Unfortunately, no such luck for KEY_UP/KEY_DOWN , which seem unfazed by SHIFT. So you can distinguish by the returned char from getch() - the KEY_S.. implies shift was pressed.

有关ALT（有什么不被困X或水族窗口管理器，至少），注册表将密钥转换为一个M ...什么的。

For ALT (what's not trapped by X or the Aqua Windowmanager, at least), keyname will convert the key to an M... something.

有关CTRL你会得到一个^preceding实际的键名。例如^ R键为18

For CTRL you'll get a "^" preceding the actual key name. E.g ^R for key 18

所以，你现在可以计算出密钥codeS为交换机（残培）语句等，通过简单的片断：

So you can now figure out the key codes for your switch(getch) statements, etc, by a simple snippet:

ch = getch(); endwin(); printf("KEY NAME : %s - %d\n", keyname(ch),ch);

，就是这样。明确地说不能想想之前。也许有这是不太明显的方式。

and that's that. Think before definitively saying "can't". Maybe there's a way that's less obvious.
