如何在C ++中并行执行系统命令 [英] How to execute system command in parallel in c++

问题描述

通常，当我想从C ++代码运行可执行文件时.我只使用代码:

Normally when I want to run a executable from a c++ code. I just use the code:

system("path\to\the\executable param"); 

现在，我想并行运行可执行文件.我使用2个线程.第一个线程将调用:

Now, I want to run the executable file in parallel. I use 2 threads. The first thread will call:

system("path\to\the\executable param1");

第二个线程将调用:

system("path\to\the\executable param2");

但是，它并没有像我期望的那样并行运行.

However it doesn't run in parallel as I expect.

有办法解决这个问题吗?

Is there in way to solve this?

推荐答案

您可以运行以下多个命令:

You can run multiple commands as below:

system("path\\to\\the\\executable param1 &");
system("path\\to\\the\\executable param2");

这样，两者都可以并行运行，并且您的程序不需要为此使用多线程.

This way both will run in parallel, and your program doesn't need to be multi-threaded for this.
