调用“系统"时抑制控制台在 C++ 中 [英] Suppress console when calling "system" in C++

问题描述

我在 C++ 中使用 system 命令来调用一些外部程序，每当我使用它时，控制台窗口都会在命令完成后打开和关闭.

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?如果解决方案可以独立于平台，我会很高兴.我还想让我的程序等到命令完成.

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

听起来你在用windows.

It sounds like you're using windows.

在 Linux(和一般的 *nix)上，我会分别将对 system 的调用替换为对 fork 和 exec 的调用.在 Windows 上，我认为 Windows API 中有某种 spawn-a-new-process 函数——请查阅文档.

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.

当您运行 shell 命令和/或外部程序时，您的程序很难独立于平台，因为它取决于具有您正在运行的命令和/或外部程序的平台.

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.
