在调用“ system”时抑制控制台。在C ++中 [英] Suppress console when calling "system" in C++

问题描述

我正在使用C ++中的 system 命令来调用某些外部程序，并且每当我使用它时，控制台窗口就会在命令完成后打开和关闭。

如何避免打开控制台窗口？如果解决方案可以独立于平台，我将很高兴。我也希望程序等待命令执行完毕。

解决方案

听起来您正在使用Windows。 / p>

在Linux（通常是* nix）上，我将对 system 的调用替换为对<$的调用c $ c> fork 和 exec 。在Windows上，我认为Windows API中有某种生成新进程功能-请查阅文档。

在运行shell命令时， /或外部程序，您的程序很难与平台无关，因为它取决于所运行的命令和/或外部程序的平台。

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.

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.

解决方案

It sounds like you're using windows.

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.

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.
