使得valgrind能够在c ++需要它时读取用户输入 [英] making valgrind able to read user input when c++ needs it

问题描述

我试图用valgrind运行我的c + +程序，但我有一些点在程序中需要用户从stdin输入，但是当我运行valgrind，它不会让用户输入任何程序，是有一个方法呢？

已全部搜索，但尚未找到答案。

解决方案

我没有尝试，但我发现这在手册页：

   -  input-fd =< number> ; [default：0，stdin] 
指定用于从
用户读取输入的文件描述符。每当valgrind需要提示用户
作出决定时使用。 
 

如果你为valgrind指定一个不同的fd（比如说3）来输入，会发生什么？ / p>


I am trying to run my c++ program with valgrind, however I have some points in the program which require user input from stdin, but when i run with valgrind, it wont let the user input anything for the program, is there a way around this?

Been searching all around but have not found the answer.

解决方案

I haven't tried it, but I found this in the man pages:

--input-fd=<number> [default: 0, stdin]
              Specify the file descriptor to use for reading  input  from  the
              user.  This  is  used whenever valgrind needs to prompt the user
              for a decision.

What happens if you specify a different fd (say, 3) for valgrind to use for input?
