当呼叫“系统”时，抑制控制台在c ++ [英] Supress console when calling "system" in c++

问题描述

我使用C ++中的 system 命令调用一些外部程序，每当我使用它时，控制台窗口在命令完成后打开并关闭。

I'm using the system command in C++ to call some external program, and whenever I use it, a console window opens and closes after the command finishes.

如何避免打开控制台窗口？如果解决方案可以是平台无关的，我会很高兴。

How can I avoid the opening of a console window? I would be happy if the solution could be platform-independent. I would also like for my program to wait until the command is finished.

推荐答案

这听起来像是在使用窗口。

It sounds like you're using windows.

在Linux上（通常是* nix），我会替换 system c $ c> fork 和 exec 。在Windows上，我认为在Windows API中有某种类型的spawn-a-new-process函数，请参阅文档。

On Linux (and *nix in general), I'd replace the call to system with calls to fork and exec, respectively. On windows, I think there is some kind of spawn-a-new-process function in the Windows API—consult the documentation.

当你运行shell命令和/或外部程序，您的程序很难使平台无关，因为它将取决于具有命令和/或您正在运行的外部程序的平台。

When you're running shell commands and/or external programs, your program is hard to make platform-independent, as it will depend on the platform having the commands and/or external programs you're running.
