如何指定程序可以在C ++中运行的最长时间

Question

In my C++ program, I will start other programs with exec. However, I want to be able to specify a maximum amount of time that the programs can run. How can that be done?

Is setrlimit the right thing to use?

Answer 1

蛮力的版本，但是...保存/获取已启动程序/进程的句柄，启动计时器并在计时器到期后终止其他进程？

Answer 2

2 solutions that comes to mind.

1- Send the duration to the second program via the command line and manage the duration internally in the 2nd exe. 2- Create a timer in the first exe and when the timer is triggered kill the 2nd process.

Max.

Answer 3

通常，这不能使用标准c ++来完成-您将不得不使用操作系统（未指定）提供的任何调度功能。
