通过windows的内核对象JobObject实现对程序的运行时间和内存使用的控制,开发初衷是作为一个简陋的acm判题沙箱.
大致步骤:
1.通过CreateJobObject创建一个工作对象
2.通过SetInformationJobObject设置工作对象的参数,详见MSDN(http://msdn.microsoft.com/zh-cn/library/ms686216)
3.以CREATE_SUSPENDED方式启动进程,通过CreateProcessAsUser或者CreateProcess函数,可能还有其他函数,未做研究.
4.通过AssignProcessToJobObject将工作对象应用到指定进程中.
5.通过ResumeThread恢复已暂停的进程.
6.通过WaitForSingleObject等待正在运行的工作对象,设置好允许使用时间.
7.通过QueryInformationJobObject获取工作对象的最终状态.运行程序的退出状态可以通过GetExitCodeProcess获取.
8.扫尾工作(必须使用TerminateJobObject结束当前的工作对象,因为工作对象即便设置了PerProcessUserTimeLimit也无法使程序在超时后退出,没有研究原因).
编译时请包含Kernel32.lib.-By the windows kernel objects JobObject control program run time and memory usage, originally developed as a rudimentary the acm sentenced Title sandbox. Roughly steps: 1. Through CreateJobObject create a work object 2.
