问题描述
我想允许用户使用命令行界面输入密码。但我不想在屏幕上显示此密码(或显示****)。
I want to allow users to enter password using command-line interface. but I don't want to display this password on screen (or display "****").
如何做到在C?
谢谢你。
How to do it in C?Thanks.
更新:
我只工作在Linux上。所以我不真正关心赢或其他系统。我想卢卡斯的解决方案,它工作得很好。不过,我还有另一个问题:
I'm working on Linux only. So I don't actually care about Win or other systems. I tried Lucas' solution and it worked fine. However, I still have another question:
-
如果这是一个单一的过程和放大器;单线程应用程序,termios的不断变化的设置会影响不同的终端?
If this is a single process & single thread app, changing setting of termios affects different terminals?
如何处理1 - 多线程,多进程 - 多线程
How about 1 process - multi threads, multi processes - multi threads?
非常感谢。
推荐答案
如果您的系统提供了它,的是一个选项:
If your system provides it, getpass is an option:
#include <unistd.h>
/* ... */
char *password = getpass("Password: ");
作为字符键入这将不会显示任何内容。
This will not display anything as characters are typed.
